Retail lighting focus: FMCG and Big Box retailers

Is there a future for unconnected lighting ?

Lighting Sandton's EmbassyTowers

P roving that a change in lighting can save retailers money, and at the same time increase sales, would make a very persuasive argument. Numerous studies have been conducted to substantiate this, among them a 21-week field research project by Dutch supermarket group, Plus, and Philips Lighting in 2010. Using different LED-based lighting scenarios, the study was designed to mea- sure the impact of light on customer buying behaviour. CQM was enlisted as an external market research agency along with the Retail Design Research Lab of the PHL University of Hasselt to evaluate the return on investment for retailers from implementing LED lighting solutions. A tracking system was installed in shoppers’ grocery baskets to trace shopping habits such as the time spent in certain parts of the supermarket, their routes around the store and parts of the shop they were drawn to. AmbiScene-controlled lighting was fitted on the one side of the store, while the other side of the supermarket was lit with traditional lighting and different lighting scenarios were applied over alternating days. The results showed that the introduction of the lighting system increased basket sales, with the average sales per customer up by 1.93 percent related to the dynamic lighting installation. Further analysis of the results also showed that customers spent more time in the areas lit with warmer light settings than those with cooler ones. Lighting manufacturer Zumtobel claims a fashion retailer in Germany saw its sales go up by around 12 percent compared to another local store after it installed a new lighting scheme specially designed to appeal to the personality profile of its target customers. Another study, conducted by independent lighting researcher Dr Colette Knight, found that objects can appear more attractive under a light source that is slightly outside the traditional colour range for white light. Participants in the study showed a strong preference for lights which increase the saturation of reds, blues and pinks and make whites appear ‘cleaner’. Knight’s report concluded: “With the maturity of LED lighting, there is now growing focus to look beyond mimicking the light properties of conventional sources. ... By cleverly designing the light spectrum, it is possible to generate various light impressions and optimise the colour appear- ance of objects.” What is clear from the above – although scientifically proving the results is virtu- ally impossible – is that lighting in a retail environment does matter. While some retailers view it as just one of the numerous aspects to their stores, others, such as the two contrasting retail projects we present in this issue, see lighting for what it is (and can be); an aspect that plays a vital role in bringing the whole design of the store together, and attracting/retaining customers.

Embassy Towers stands proud as an icon

Embassy Towers in Sandhurst is an exclusive apartment building in the heart of the Sandton CBD.

T ucked behind the United States Consulate, the building enjoys breath-taking views across to the Magaliesberg Mountains as well as to the south, east and westerly directions owing to the residential scale of surrounding neigh- bours.This attractive building can be seen towering on the Sandton City skyline and, together with GLH Architects, One Zero Electrical Engineers and Paul Pamboukian & Associates, Regent Lighting Solutions (RLS) supplied lighting to accentuate the façade of the building from roof to ground level. The building is positioned close to the street frontage on Empire Place to provide large, lush private gardens, with many of the mature trees retained from the original residential property. This garden scape and the residential scale of the surrounding properties ensure that views are unimpeded, creating the sense of a large parkland property, but with the convenience of being within the Sandton CBD. The sparkling lights of Sandton are juxtaposed with the ample privacy and greenery of the garden, reminiscent of the apartment buildings of Central Park in NewYork or Hyde Park in London.The natu- ral fall of the site allowed for the entrance floor of the building to be situated at street level while the elevation allows for the ground floor public area to look out over neighbouring properties.This enables

a view of Sandton to unfold upon entering through the large glass doors of the reception while retain- ing a human scale on the street frontage. The façade of the building is dramatically en- hanced with LED cove lighting IP Rated at 14W/m LED 2700 K, with BeamDouble 2 x 32WLED 3000 wall mounted fittings accentuating the architectural lines of the façade. The parking areas feature the Piazza, which is implemented in all street, parking area and land- scape applications. This fitting is post mounted to a height of 3.5 m to 5 m and designed to operate a range of LEDs up to 48 W with various modular optical lenses. The application at Embassy Towers incorporated camera surveillance on all Piazza

The 9W LED 3000 K Piazza pedestrian bollards surrounding the walkways mimic this design style while the landscape and planter boxes at the exterior feature numerous fittings including the Gamma trunion, Kevo trunion, Bilux Inground, Brite 50 Inground and Eclipse. The build- ing entrance overhang features recessed Floren 30° 40 W LED 3000 K and Special Brite 50 3 W 3000 K 46° fittings.

The interior luminaires supplied on this project were Linear Micro 1000 mm 23 W/m LED 3000 K and Linear Mini 1200 mm 16 W LED surface mounted, with Jura 1 007 tracklights 18 W LED 4000 K to showcase the wall art throughout the interior. The apartment interiors have a recessed panel in the ceiling to house the Kalypso Single and Double surface mounted luminaires, which are adjustable on the vertical and horizontal plane.

Embassy Towers, an iconic landmark for San- don is set to become a world-class destination. The 12 storey tower with an impressive mix of two and three bedroom apartments and bespoke penthouses was conceived to integrate effortlessly with the stylish central Sandton district, yet stand proud as an icon and inspiration for future develop- ments.The lighting design of the project enables it to succeed on both fronts.

The One&Only Le Saint Géran has set new standards of ultra-luxury on the island of Mauritius as it welcomes guests back following a multimillion dollar investment. W ith its own private peninsula – with a beachfront and calm lagoon – the One&Only Le Saint Géran has always retained a sense of exclusive seclusion.The resort’s colonial-style architecture has been faithfully pre- served and incorporates stylish design references to traditional Mauritian lifestyle and architecture.To ensure it continues to showcase what its guests have come to love, the resort recently underwent a major refurbishment. Illuminating a legendary Mauritian hotel

The new guest rooms feature gracious living spaces in a contemporary, timeless design while retaining a relaxed island feel. Strong focus has been placed on showcasing the magnificent views and surroundings of the resort, with muted hues of warm white marble, teak and greys being used to reflect the spectacular environment. Interior design companies, dsgn and G.A Design, worked closely with the resort team to ensure the interior design and architecture of all rooms captured the essence of Mauritius while keeping One&Only ideals inmind. The sophisticated interiors of each guest room and suite are finished with natural materials, and be- spoke furniture and locally-crafted lithographs have been selected to resonatewith the environment and provide an idyll of understated style.

correct LED and battery technology to meet the needs of the backup lighting specifications provided by the electrical contractor, in the event of a loss of electrical power at the hotel. “Quite a lot of focus was on the colour tem- perature of the lights,” saysWagener. “Softer hues were installed into areas of rest and relaxation while white light was used in areas where food was dis- played, including the breakfast station food displays as well as in the commercial and retail centres.

Our position was to explain what was practically possible from a manufacturing time-line and cost perspective”. Illumina manufactured more than 2500 units for the guest rooms for dsgn and a number of the public open spaces, the latter of which were designed by G.A Design. Each space had its own requirements.

implemented to give this area an enchanting glow at night.We are also especially happy with the units we manufactured for the Prime restaurant as well as the Provedor restaurant, which showcases our abilities with regards to manufacturing with glass." Ultimately, the manner in which the lights come together to complement the spaces in which the guests move around the hotel contributed to the suc- cess of the project. “A light must become invisible, and become one with its environment, unless you require a statement piece,” saysWagener. “The lights at Le Saint Geran are practical in design but imbue quality and style”. On the importance of lighting in a hospitality en- vironment,Wagener says many factors are important in the design of a space. “While training in London on street lighting design it became even more appar- ent how we take lighting for granted and the amount of work that goes into designing a lighting scheme. Hospitality projects have numerous areas that require specific designs and the challenge is not to over-light or under-light. Incorrect lighting can cause discomfort, therefore lighting design is a very important factor to the success of any hotel, small or large.” Every project has its unique challenges and Wagener notes that One&Only Le Saint Géran was no different. “There is no doubt that the timeframe in which we had to achieve design approval before manufacturing could start was a challenge. Both dsgn and G.A Design were committed to the timelines but were firm on finding the best result for the client.We learned a lot from the teams we had the privilege of working with. December, however, is not a month you want to ship goods out of China – another unique challenge. It was a pressure environment for a few months but it all came together collectively in the end,” he says. “We are proud to be associated with prestigious brands such as Kerzner and One&Only,” saysWagener. “I personally oversaw the start of the manufacturing process in China and was present in Mauritius for the installation process, and put a lot time and effort into the project. Looking back at a challenging and rewarding project, we are always looking to learn and better our processes, and these improved processes are already being implemented in projects such as The Houghton Hotel in Sandton.” As testament to the quality of the light fittings used, Wagener notes that the company has already had hotel guests ordering fittings for their private homes in France, Belgium and Germany.

Big impact for this fresh take on ‘big box’ retail

Leroy Merlin – the world’s largest home improvement retailer, and present in 13 countries – has made its first foray into the African market with the opening of a store at Redefine Properties’ Stoneridge Centre in Greenstone, Johannesburg.

R edefine Properties’ development teamhad to substantially remodel the specification docu- ment designed for a European environment to provide a new two level configuration to suit the South African environment and ensure consistency of look and feel across Leroy Merlin’s global stores. Occupying close to 17 000 m 2 and covering two floors – parking and a drive-through building materi- als yard on the lower level and showrooms, trading floor, storage area, office space as well as a pick up zone on the upper level – Leroy Merlin stores offer

a variety of internationally-sourced products with specialised advice and training for customers of any level of DIY expertise. The stores normally carry anywhere between 30 000 to 60 000 products, with Leroy Merlin’s customer focused employees able to offer sound advice on solutions, products and installations. “We want customers to have an adventure at Leroy Merlin, and the building plays a role in that – using architecture to create an environment where customers will be comfortable,” says Patrycja

forms for the trading area, but then it’s a bit like Lego ... you play with it and adapt it,” Pelkowska says. “This store is similar to Leroy Merlin stores over- seas, but we do keep the design open and leave elements for local identification,” says Pelkowska, although the basic technical rule of a crisp, white store which doesn’t interrupt the customer experi- ence is synonymous with the brand worldwide. It is a far cry from the dark and dingy hardware stores of the past, and the interiors are designed with younger generations and female shoppers in mind. The important role of lighting “From a lighting perspective, our brief is sleek light lines,” says Pelkowska. “The general lighting layout is LED fixtures at 6 m, with focused lighting for the showroom areas and special exhibitions.”The archi- tects asked for 700 lux in the trading areas, higher and warmer than you would find in similar stores. “There are no accidents in what we specify – every aspect of the requirements is precise, hence the lux and our warm white colour requirement.” As the height of the in-store racks is not uniform throughout, this meant that the penetration of light was not uniform throughout. “We performed numerous tests because there were places in the store which I felt were a bit dark. The 700 lux level is our minimum, but in zones where racks obstruct the light, or dark products absorb light, we added extra spotlights as we did in areas where we tried to focus the attention of the customers on ‘star’ products,” she says. Pelkowska notes that in certain areas there are almost “theatrical installations” of lighting to highlight items. A ‘soft’ BMS system is employed, and with nu- merous skylights providing natural light, the use of interior lighting in the store will be optimised once the tenants get used to the day-to-day running of the building. “With the natural lighting you have

Pelkowska, Leroy Merlin’s in-house architect along with Thomas Lanier. After five years of research and planning, Leroy Merlin is taking an uncharacteristically aggressive approach to South Africa, opening three further stores in the next year in Roodepoort, Boksburg and in Fourways, alongside the Fourways Mall re- development. Having designed and built 15 Leroy Merlin stores in Russia and redeveloped a further 15 retailers into Leroy Merlin stores in Romania, Pelkowska now heads up the company’s architec- tural design and construction into new markets. The site was handed over in April 2017 and the 16 000 m 2 store, with additional offices of 700 m 2 (including a kitchen, showers, changing rooms, bathrooms, and break areas for staff), opened this September.With 35 000 different products and 120 members of staff, Leroy Merlin presents a markedly different DIY shopping experience for customers. “It is about the vibe people get when they shop here and the modern, clean, bright interiors of the store reflect this,” says Pelkowska. Lanier, a French architect who has been based in South Africa for almost two decades, notes that the South African context is quite interesting for Leroy Merlin. “Much of the local population, especially in the areas where we are building the stores, is well travelled, educated, sophisticated and openminded. We couldn’t just come with a big box and expect people to react well to that; we needed to deliver something user friendly. This, he explains, is done through a mix of elements, notably quality of light, colour schemes, and materials and textures used, which sets Leroy Merlin apart from the opposition. “As architects we have to be conscious of rack layouts in the store.The merchandising department has certain rules about rack layouts, how large the alley is, how deep the racks are, how many racks need to be placed, the width of the main passage, etc, – so we are given the general dimensions and

here in South Africa, I thought, ‘wow, maybe we can just turn everything off!’ During sunny days, I believe that most of the lighting in store could ac- tually be used for marketing purposes rather than functional lighting needs,” says Pelkowska. Externally, street lighting is provided in the parking area, but it is the Leroy Merlin signage that catches the eye. “It is actually an optical illusion,” explains Pelkowska. The signage is dark green, al- though the double printed vinyl banner on light boxes appears black during the day because of the contrast with the exterior’s white cladding and the blue sky. Once lit at night, the rich corporate green acts as a beacon for the store. Lanier explains that the perfect solution for lighting the large triangle that forms the company’s logo and offers a hint of the scale of the building, would have been to have it backlit, but this was a challenge owing to its size and maintenance needs. “Here we concentrated the façade lighting on the triangle without much light loss, as our park- ing light requirement level is already high, and also projects onto the elevation of the building.” Looking back on the company’s first store in Africa, Pelkowska is happy with the way local con- tractors and suppliers worked with the “strange animal from France telling them what to do”. While there were a few struggles with the quality of the execution of the work, the team is positive it can learn from this first experience. “It is not easy to break habits, but we have worked on projects that have been a lot more difficult than this one. On the electrical side, the electrical engineers, Monty Miller Associates, were very hands-on and worked really closely with us, and we are very happy to have them on board at the Boksburg store as well.” By using as many local suppliers as possible and holding them to exacting European standards, in Greenstone, Leroy Merlin has created a world class retail environment which could signify a shift in South African consumers’ hardware spend, and lighting has proved to be key in the realisation of this store.

From the lighting supplier Kevin Murphy from the lighting suppliers, Province Lighting, says that for the first Leroy Merlin store in the country, and with so many variables to work around, the project was a resounding success. “We supplied all the lighting for the store – over 2000 base LED fit- tings for the trading floor as well as all external lighting,” he says. A unique feature of the lighting is that a 3000 K colour temperature was specified, as opposed to the usual 4000 K for this sort of environment. “This adds lots of warmth to the store, providing a totally different retail experience,” he says. “Leroy Merlin was very specific about the required lux levels on the trading floor, so we carried out a general layout across the board before all the shelves and racking were installed and once they were up we were very close to what was required. “Despite the usual minor challenges, which are common on a project of this size, Province Lighting is very excited about the overall re- sult of this project and the aggressive rollout from Leroy Merlin, and hopes to be involved in future stores,” says Murphy.

S koutellas, owner of SPAR stores in Bedford- view and Sunninghill, turned to a familiar team when upgrading the Blackheath SU- PERSPAR, doubling its size and incorporating a TOPS at SPAR liquor store.Tasked with the lighting was Flolite, which played an integral role in the re- vamp of the successful SUPERSPAR Bedfordview. “We have worked on more than 100 SPAR stores, and with George we had already worked on two of his other stores, so he is confident working with us; he knows our level of service and the end result. Consequently, we are familiar with retail and the standards expected by SPAR,” says Flolite’s John Dewet. Initially 250 m 2 , the store now comprises a ‘fresh’ department, which includes an extended range to the butchery, bakery, deli, gift shop and flower offering, along with a brand new coffee shop, while the newTOPS at SPAR boasts a 100 m 2 walk-in beer chiller. Having been involved in similar stores previ- ously, Dewet says that at the first site meeting they were asked to “do your magic”. He notes, “The client wanted the store to ‘stand out’ from a lighting perspective. Following our previous work on the flagship Bedfordview store three years ago, this project was required to surpass it, so we had to push the envelope that bit further”. Met with what can be described as a rundown and dingy store, Flolite increased the standard lux When George Skoutellas – known by many in the industry as ‘Mr SPAR’ – acquired the SUPERSPAR Blackheath in the northern suburbs of Gauteng, he embarked on an ambitious plan to renovate and expand a flailing store.

levels of 800 in retail aisles to 1100. “This was a little more challenging, but the end result is that the products ‘pop’ from the shelves and, along with the correct colour rendering index, provide a true reflection of their colours.” He says Flolite keeps track of trends in FMCG retail in the States, where thin LED strips are being placed on grocery shelves to further highlight items and studies show that sales can increase by 25% on highlighted products as they stand out for consumers. Specialised handmade fittings were installed for aesthetic value in the more ostentatious areas of the store. For instance, for the coffee shop area and the home meal replacement (HMR) section, a selection of brass and wire pendants with Edison bulbs add a more homely feel compared to the rest of the store. Elsewhere, over 150 54 W linear battens were installed in the recesses of the ceiling’s bulkheads, while lighting – although more functional – was also required for the back-of-house receiving and office areas. Despite a large glass shopfront, natural light didn’t play much into the mix as its penetration was less than 6 m into the store; here softer lighting with lower lux levels was used to create a more comfortable working environment for the cashiers. Overall, 170 linear highbays, 150 batten fittings, 80 downlights and over 100 track lights were installed in the two stores.

TheTOPS at SPAR store, with its own entrance and cleverly divided from the SUPERSPAR Blackheath by a translucent liquor cabinet which entices customers to visit both entities, follows the same lighting concept as the SPAR store but with a slightly smaller 600 mm x 600 mm light. For the fridges, specially de- signed luminaires were installed which can operate at -40°C. Externally, Flolite also devel- oped a new parking light product for the parking lot. “We installed a high lumen output, 300 W fitting for the parking lot. Previ- ously, it was not a well-lit area and crimes had occurred there. By increasing the lux levels from the typical 50-70 to 120 lux out- side, customers now feel more comfortable parking there in the evenings and using the outdoor ATM,” says Dewet. Challenges “Retail calls for very specific lighting and the new design has

seen turnover increase quite dramati- cally at the store, but it also comes with numerous challenges,” he says. As is often the case, the renovation had to be done while the store remained open for trading. “As such, our noise levels had to be kept to a minimum and there is always an element of danger when working with live power and in close proximity to the general public.” In this situation, light- ing suppliers are often asked to provide temporary lighting for other construction services; “Where possible we try and install the final product for this scenario and deal with the aftermath of replacing and cleaning the fittings once everything else is done,” says Dewet. “I would hazard a guess that around 70-80% of retail stores in South Africa are under lit,” he says, adding that many retailers from the SPAR group have al- ready visited the Blackheath store to see the difference lighting can make. “It is amazing how, when a retail store is under lit, it will gradually start losing custom- ers. People gravitate subconsciously to a better illuminated store where they feel more comfortable. “Retailers should keep the lighting fresh and alive, and let the CRI do the work as it tends to sell the products. Many retailers cut corners when it comes to lighting, and when they don’t get the results, have to redo it properly at further expense,” concludes Dewet.

Trends in street lighting

W ith various cities throughout the world investing in modern street lighting, cities are beginning to become more contem- porary in design. Whether the fixtures are in Paris, Los Angeles or Johannesburg, modern streetlights offer far more than just light on a dark street. BEKA Schréder’s Product Development Man- ager, Daniel Kasper, and Senior Lighting Designer, Retief Coetzer, discuss the current street lighting market. Perhaps the biggest concern for us is that there are a lot of ‘cowboys’ out there using cheap luminaires or imitations and not applying the correct approach to design with regards to standards that provide adequate, safe and responsible street lighting. Also, in many cases, the end-user or client does not know any better and relies on these ‘cowboys’ for accurate information.This is a concern once the street lighting is installed as those in danger are the pedestrians, cyclists and motorists. Further to this, end users of LED luminaires are often mislead by warranty claims which, in most cases, do not warrant the most likely failure of LED luminaires, which is surges or power sup- ply fluctuations, or abnormal daytime operation. Unfortunately, there is a general lack of knowledge within the lighting industry and among end users when it comes to fast changing and vibrant LED technology, and people can be misled by the prod- uct information provided. What are the major concerns when it comes to street lighting installations?

Is there an industry standard for street lighting? There is the safety standard SANS 60598, the performance standard SANS 475 and the SATS 17576 technical performance specification. Further to this, there are standards available relating to ad- ditional requirements such as impact, vibration and photobiological conformance. Yes. We are currently busy installing a major road in Johannesburg, consisting of eight phases, with our OWLET enabled streetlighting lumi- naires. This will achieve significant savings over time for the municipality and the residents, and will reduce the toll on the already strained power utility. Furthermore, it will give the municipality a fully detailed and updated asset register and will provide greatly improved service delivery in the case of replacement of faulty luminaires on site. We also have the new Shuffle, which is as smart as they come. Wi-Fi, CCTV, electric charging point for electric vehicles, speakers with a range of optics that are also used for op- timal spacing without cost to performance and standards. This range of street/urban luminaire systems has already started making waves inter- nationally and we have installed them in certain private estates. It’s a very hopeful future when government starts investing in these types of luminaires with the vision of saving money, elec- tricity and the environment for the betterment of the country’s citizens. Is smart lighting, as standard, on the horizon for street lights in South Africa?

HESTIA Mini LED luminaires on curved poles illuminate Richmond Park.

What is the optimum co- lour temperature for street lighting? That depends on who you ask, and what literature you read. Some might say 2700 K and others 6500 K. A recent study by the AMA on blue light in LED luminaires having a negative effect on human circadian rhythms and damag- ing our eyes in streetlighting applications was, in our opin- ion, utterly disproved by Dr Ian Ashdown, Senior Scientist at SunTracker Technologies Ltd, in one of his blogs in

How the design of streets could change in real-time Carlo Ratti Associati, working in collaboration with Alphabet’s Sidewalk Labs, has unveiled a design for a modular paving system namedThe Dynamic Street. Intended to make streets “reconfigurable, safer, and more accessible to pedestrians, cyclists, and tomorrow’s self-driving vehicles,” the project will be on display at Sidewalk Lab’s office and experimentation space in Toronto throughout the summer of 2018. Manifesting as a series of hexagonal modular pavers, the project explores the various patterns which can be created by reconfiguring modules, with a potential future of“ allowing a street to create an extra car lane during rush hour before, then turning it into a pedestrian-only plaza in the evening.” The prototype contains embedded lights in all 232 modules capable of communicating crossings, pick-up zones, and other uses. Potential also exists for each module to host a plug and play element, including poles, bollards, or basketball hoops.

2014, and by the following scientific publication: https://ec.europa.eu/health/sites/health/files/sci- entific_committees/scheer/docs/scheer_o_011.pdf. We would recommend 4000 K, as it has a nice ‘natural’ lighting feel without the blue wavelength being obvious to the observer, as is the case in luminaires of 6000 K and above. Yes, but mostly in the Western Cape – especially CapeTown – and Durban.We have recently installed LED street lighting on SimonVermooten Street and Atterbury Road near Menlyn in Pretoria to mention two. These are great examples of wonderful road/ street lighting applications which not only ensure safer driving environments, but also a general feel- ing of safer movement in the open for cyclists and pedestrians. We have a great and practical range of streetlight luminaires for almost every type of road that could possibly be found in this country, and the continent. In our LED range of luminaires, we use a wide variety of specially designed optics to ensure opti- mal and maximum spacing while still maintaining standards for street/road light applications. Our luminaires are optimised to meet and sustain the harsh environmental conditions they are exposed to, which include strong corrosive atmospheres, dusty air and surges. www.beka-schreder.co.za Are LEDs becoming the norm for street light- ing locally?

How to light a bathroom Being of the most functional spaces in a home, bathrooms need the right type of lighting. However, good bathroom lighting is not only functional – well-considered lighting can take a bathroom’s overall aesthetic from drab to fab, with the 'flick of a switch' or 'touch of a screen'.

Ambient lighting Experts at Eurolux believe that ideally a bathroom’s main source of light should come from downlight- ers and here sealed waterproof downlights above the shower are important as constant exposure to steam can lead to electrical problems at a later stage. This being said, downlighters are costly. Designers looking for a more budget-friendly op- tion could use a circular, sealed fluorescent fitting, which offers sufficient light for good visibility and does not use much electricity. It is also a sensible option if the bathroom light in the home gets left on throughout the night for young children. Mirror lighting Bathroom mirrors and good lighting go hand-in- hand. The most important thing about mirror lights is that, for the most accurate reflection of the user, they need to make people’s faces look even and shadow-free. To achieve the shadow-free look, the mirror light should shine towards the face rather than onto the mirror and straight back at the user. Instead of reflecting the light glare of the fitting, the image reflected in the mirror will be well il- luminated. If the mirror is square, rectangular or round then

luminaires on either side of it will illuminate the reflection best. If the mirror is diamond or octagonal in shape it is advisable to light it from above. Tilted lights on either side of the mirror are guaranteed to give the best effect. They need to be installed with precision, and work best if positioned on the wall as close to the mirror on either side as possible. Cabinet lighting Eurolux suggests installing lighting in the cabinet under the sink, where under-counter lighting or LED strip lights work well. Designers may also want to consider placing a battery-operated touch light in this space, which would come in handy in the event of a power outage. Sensor lights Spaces that are used infrequently, such as a guest bathroom, call for sensor lights. These lights only come on when movement is detected and remain on for a set period of time. Sensor lights are pro- grammed only to turn on when the light levels are low so they are excellent energy savers too.

Bathroom lighting from an architect’s perspective When it comes to proper lighting, one of the most critical rooms in the home is the bathroom, notes architect Doug Walter. It is often the first place people go to when they wake up in the morning, and it can set the mood for the day.The bathroom is where you wash and groom, and many people take their morning medications there – all strong cases for optimised lighting and daylighting. The other reason is that light, particularly daylight, is what sets our circadian rhythms, which play an important part in overall health. Helping people see well is also critical for safety, since the bathroom is where 80 percent of older adults experience a fall. Fortunately, good lighting for seniors is good lighting for everyone. “For effective bath lighting of any sort, it’s smart to pay attention to the CRI (colour rendering index),” says Walter. “A number of 100 is ideal but hard to find. Anything over 80 will allow people to see colours fairly accurately. Also don’t forget to specify the colour temperature, expressed in degrees Kelvin (K). A 2700 K lamp is about the same warm yellow light as an incandescent bulb, and many clients prefer them. Jumping to a 3000 K lamp makes a whiter light, still warm, that’s a good compromise. For residential use, 3500 K is about as cool a colour as I’d recommend – it’s particularly good in closets, where you need accuracy for colour matching when choosing clothing. Many clothing stores use 3500 K lighting for that reason.

‘Unconnected lighting’ still very much alive

By Henk Rotman, Tridonic

T erms like ‘connected lighting’, ‘intelligent lighting’, and ‘Internet of Light’ are becoming mainstream as the lighting industry moves more and more towards adding connectivity to LED-based solutions. And rightfully so, since con- nected lighting offers exciting new opportunities in various lighting fields.With all the attention directed towards connected lighting, one wonders whether there is still a future for ‘unconnected lighting’. This article aims to explain the concept and advantages of connected lighting, highlighting certain conditions and roadblocks, while making the case that for the short – and medium term – ‘unconnected lighting’ offers many benefits to major parts of the market. IoT and connected lighting With the Internet ofThings, data is generated by a de- vice (i.e. a ‘thing’).Transfer of data is between ‘things’ with embedded sensors and a central system that collects and organises the data from the sensors. The IoT creates enhanced efficiencies of systems and processes that benefit humans, the spaces we live and work in, the environment, and more. We are at the early stage of what the IoT will enable; we see just a fraction of potential applica- tions.The IoT has been labelled ‘the next industrial revolution’. To describe connected lighting in simple terms: it is a lighting device connected to the internet. As light- ing is present not only in buildings and houses, but in cities as well, it is the perfect ‘vehicle’ for collect-

ing data. Sensors embedded in luminaires or lamps make each light point a data node on the network.

Benefits of connected lighting The lighting industry has for a long time been able to connect lighting devices and sensors to one another, for example, in an office as part of a Build- ing Management System.These systems allow for control and management of the lighting while also gathering important information on energy-usage, for example. The scope of Building Management Systems is not only lighting, but also security, air handling, energy usage and so on. In ‘traditional’ BMSs there is little or no interaction between these technolo- gies as they operate more or less in ‘silos’. With the rise of the IoT, all devices in an office are connected to the internet and data can flow from one device to another. This opens up excit- ing new opportunities to translate the data into information with tangible benefits. As mentioned earlier, we are still in the early stages of the IoT and connected lighting, but we can already clearly see the benefits of implement- ing connected lighting. These benefits differ ac- cording to the main application. For office use the main benefits are: - Providing insight to facilitymanagers aroundwork- space occupancy; allowing them to maximise space utilisation and save on real estate costs. - Accurate information on energy-usage.

immediately translates into cost savings. However, this benefit is relevant mainly to larger offices, where there is the possibility to reduce the space occupied, for example, if a company occupies six floors in an office tower andmonitoring workspace use tells the facilitymanager that vacating one floor is a possibility – this generates a substantial saving. In small – and even medium-sized offices – this is often not pos- sible as the physical set-up of the office does not allow for reduction of the space. At the same time, small and medium sized offices usually do not have a facility manager able to convert the data generated by connected lighting into information concerning efficient use of available space. In small andmedium sized offices, the facility management task is often combined with other tasks and the person in the position is able to get a good impression of efficient use of space simply by walking around. The other benefit of connected lighting, that of personalising the lighting of workspace or meet- ing rooms, also requires a practical perspective. Worldwide organisations are changing their offices to open plan, often with ‘hot desks’, meaning em- ployees share a larger office space and often no longer have their own personal desks.This severely limits the possibility of employees personalising their workspace lighting as the lighting is shared by many employees and there are potential conflicts (for instance, one employee may prefer warmwhite light while the person at the next desk prefers very cool white light). Personalising the lighting in meeting rooms remains an option in modern offices but, to allow this, the lighting does not need to be connected as room-based controls have made this possible for many years. Conditions of connected lighting Compared to ‘unconnected lighting’ a lighting project based on connected lighting requires the following elements:

- Personalised lighting in employee workspaces, or in meeting rooms, to ensure the right lighting for the task at hand. With the evolvement of the IoT we can expect the benefits of connected lighting to growandmore ben- efits to be added. It will be like the internet where, over time, new applications developed and resulted in the rise of whole new industries and companies. ‘Connected lighting’ versus ‘unconnected lighting’ Given all the benefits of connected lighting, a logical question is whether there is still space for ‘uncon- nected lighting’. We defined connected lighting as 'lighting devices connected to the internet’, so a logical definition of unconnected lighting would be ‘lighting devices not connected to the internet’. But unconnected lighting can still offer many benefits such as reduction of energy-use via concepts like day- light harvesting and presence detection, or increased comfort by controlling the lighting or setting scenes. Let’s try to answer the question of whether there still is a future for unconnected lighting by taking another look at connected lighting. Insight into workspace use is an important benefit because modern office space is expensive and reducing the amount of square metres used

- A higher level of investment as there is a price pre- mium for connected lighting. - Resources to analyse and evaluate the data gener- ated by the connected lighting, and translate the data into information. - As the connected lighting system is linked to the internet, an information system, the system should be secured against hackers. - The resources to install and maintain the connected lighting system. Again, the conditions listed above point to larger scale projects with sufficient budget and resources to convert data into information, implement the required level of security and realise both the initial installation and the maintenance. Looking specifically at the situation in South Africa (or Africa as a whole for that matter), available resources for installing and maintaining a connected lighting sys- tem can be a serious constraint. The number of com- panies and experts able to properly install and maintain a lighting controls installation is, unfortunately, rather limited. As connected lighting has additional challenges related to information technology, including security, only a few companies will be able to assist in connected lighting projects. What about ‘unconnected’ lighting? Unconnected lighting is able to provide many of the benefits of connected lighting, without the need for analysing data and providing a high level of security, while both installation and maintenance are less com- plicated. Based on this, for the time being, unconnected lighting will remain an excellent proposition for smaller and medium-sized projects. Unconnected lighting using so called ‘luminaire based controls’ especially are highly suitable for markets with limited specialised resources for installing sophisticated lighting systems, as the com- ponents like sensors or wireless devices are inside the luminaire.This means that an installer on site can install the luminaire like any regular luminaire as the luminaire producer has already taken care of specialised wiring or (part of) the programming. Conclusion Connected lighting, or the IoT, is an exciting proposition for the lighting industry and will grow in importance with the evolvement of the IoT. Based on the benefits at this point and the conditions for a successful implementa- tion, it seems more geared for larger scale projects. Unconnected lighting (lighting not connected to the internet) offers tangible benefits while installation and maintenance are less demanding and hence, for the short and medium term, remains an interesting option for medium and smaller sized projects. www.tridonic.com

Examples of unconnected lighting

Luminaire based controls, where controls are built into the luminaire by the luminaire producer, offer the advantage that installation is simple as it requires no additional wiring and most if not all of the programming is done by the luminaire producer. Luminaire based movement sensors are popular in South- Africa and these are easily integrated into a luminaire. Most sensors use Passive Infrared technology to detect motion. Sensors using ‘High Frequency’ or ‘Micro Wave’ technology are making inroads, as they can ‘see’ through plastic and are able to detect motion when built into a closed luminaire such as a vapour proof luminaire or a batten with a plastic cover. Adding modules able to communicate us- ing Bluetooth is another example of luminaire based controls. Again, there is no need for additional wiring. Control profiles are saved during the luminaire production stage. Users can choose whether to control the lighting via an app, phone, tablet or user interface. Luminaires can be switched on and off, or be dimmed. Lighting scenes can be created as well and, in cases where Tunable White lumi- naires are used, the colour temperature can be changed to suit the user while, in direct/ indirect luminaires, the direct and indirect light content can simply be adjusted.
