BEKA SCHRÉDER LAUNCHES NEW HIGH-POWER MODULAR LED FLOODLIGHT

BEKA Schréder recently announced the launch of its new modular LED floodlight, the OMNIblast-E, which offers an unrivalled combination of per- formance and flexibility. The locallymanufacturedOMNIblast-E is the ideal tool for sports venues and other very large area applications that require a lighting solution with the highest efficiency and flexibility to adapt to the different lighting needs. Available in three sizes, this new LED solution offers an alternative with proven benefits for traditional fixtures fitted with 600 W to 2000 W HID lamps. A modular concept of optical units means that 1, 2 or 3 modules can be mounted on a similar bracket arrangement to offer the utmost versatility, providing light distributions and lumen packages perfectly adapted to the specifications of the area to be lit. The OMNIblast-E incorporates a patented cooling technology that maximises its lifespan and lumen output. Key features of the OMNIblast-E: • As with most BEKA Schréder products, the OMNIblast-E is locally manufactured, thus taking Africa’s harsh environments and conditions into account.

• Flexibility through modular design. • Superior optical efficiency. • Advanced control options. • Manufactured from marine grade aluminium alloy to withstand any coastal corrosion area. • Cost-effective and efficient solution to maximise energy and mainte- nance savings. • Instant switch on/off (static) – we also offer an optional dynamic set- ting to create dramatic or theatrical effects. • Inclination angle adjustable on-site. To enhance the on-site experience and television images for recrea- tional and professional sport, the OMNIblast-E features glare control, a high television lighting consistency index (TLCI) as well as flicker-free lighting. Whether used for arena, stadium, university track and field, golf course, harbour, or industrial highmast lighting, the OMNIblast-E offers the ideal LED lighting solution.

LED INSTRUMENTAL IN DALMA MALL REFURBISHMENT

S prawled across 255 000 square meters, Dalma Mall in UAE’s capital, Abu Dhabi, is part of the strategic plan of the Abu Dhabi 2030 vision, which sets the framework of the Emirate’s long-term economic and social growth. It houses more than

to LED lights in order to keep in line with Abu Dhabi’s 2030 vision, which is geared towards building a sustainable and vibrant economy. They wanted to be able to cut their energy expenditures as well as minimise the maintenance work that usually comes with fluorescent lights.

450 international and local brands, a hypermarket, a hospital, 14 cinemas, and 6 300 parking spaces. The Developers Holding LLC – Dalma Mall’s owner – decided in early 2018 to refurbish the fluorescent light fittings originally installed in the mall

constant current LED drivers were installed. At least 40% energy savings as opposed to using fluorescent fittings was achieved.

easy-to-install LED modules and LED drivers were used for cove lighting application in the entire mall. 21 000 linear LLE G4 LED modules, 1 680 m LLE FLEX strip lights, and 5 400 LC SNC constant voltage and LC EXC

Initially, they considered using LED tube lights, but after several discussions and considerations, they decided to go for LED modules because of better colour consistency and longer lifetime. Finally, after several discussions and mock-ups and owing it to good service, lead time, and brand reliability, the client chose to work with Tridonic.

WHAT IS THE UNIFIED GLARE RATING? U GR stands for Unified Glare Rating. This value is an indication of the extent to which luminaires and lightsourcescause lightningfromacertainposition

• Surface brightness (luminance) of the walls, the ceiling, the floor and other large planes • Type of luminaire and shielding • Distribution of luminaires over space • Observer position The following UGR values may not be exceeded per application: • UGR value: 22 – Application: Fine industrial work  • UGR value: 25 – Application: Average industrial work • UGR value: 28 – Application: Circulation areas and corridors • UGR value: More than 28 – Application: Harmful and cannot be accepted  The UGR value differs by each workplace environment, due to the work actions performed. For example, the UGR value in stairwells is higher, because less time is spent and practically less work is achieved. • UGR value: 16 – Application: Drawing room  • UGR value: 19 – Application: Office works 

of the user. This value is based on regular patterns and fittings according to the new European recommendations for indoor lighting: EN 12464-1 standard. What is the importance of the UGR value? Lighting is an often underestimated component within companies, but deserves more attention. The productivity and well-being of an employee is greatly influenced by lighting. The light must be so clear that one can perform work, but at the same time one should not be blinded. The UGR value is therefore essential in a company. What factors play a role in determining the UGR value? Measuring the UGR value depends on certain things. To make a targeted assessment, the following factors play a role: • Shape and size of space
