BEKA SCHRÉDER LAUNCHES NEW LED POST TOP

LINEAR HIGH BAYS TO REPLACE TRADITIONAL HIGH BAYS

BEKA SCHRÉDER has launched a variety of new and exciting high-quality LED luminaires, which have been designed and manufactured in South Africa. One of them is the new LED post top, the Kazelle. The Kazelle’s minimalistic and modern look is designed around the compactness of the LED engine, which allows this post top to blend into architectural landscapes. At the same time, sustainable lighting solutions are provided that dramatically reduce energy consumption and improve visual comfort for pedestrians, cyclists and motorists. Available in either neutral white (4000 K) or warm white (3 000 K) light, the cost-effective Kazelle luminaire emits a pleasant, glare-free light. Optional control solutions are available for further energy savings. Reliable, efficient, discreet and vandal resistant, the Kazelle emits no upward lighting. Furthermore, it has been designed for easy installation. With virtually no maintenance required, the Kazelle guarantees long- lasting performance and massive savings.

shelving and racking systems, to calcu- late the most effective beam angle to maximise illuminance and effective light spread. This design with a 62 degree beam an- gle has proven to be very successful and the results speak for themselves. The CRI is <80 which allows for an ideal colour rendering in any working environ- ment. Thermal management is controlled through the Crystal Driver Technology which ensures that the products cannot fail due to high temperatures. Ellies offer a five year replacement warranty on this range of linear high bays. area’s main function is. The primary consid- eration should be the ceiling height and the foot traffic path of the room. If people will be walking under the fixture, then they must have enough room to do so without grazing the top of their heads. At the other end of the spectrum are rooms with high ceilings. Flush mount or semi-flush mount lights would look completely out of scale in such a voluminous space. Another consideration is the use of the space. The immediate area around furniture such as dining room tables, desks or beds al- lows for more flexibility as people are either seated or lying down here, so headroom is less of a concern. Closets, hallways and staircases, on the other hand, are a totally different story as objects are likely to be moved in and out of these spaces and the last thing required is a lighting fixture impeding movement.

ELLIES has designed and manufactured a linear high bay fitting which can replace traditional high bays. With proprietary technology, the products use less power and have an increased lifespan and less lumen depreciation. There are two versions available for the market, an IP20 linear high bay for indoor use and an IP65 unit with anodized fit- ting ensuring it is corrosive resistant. The range is available in both 100 W and 200 W with an efficacy of 110 lm per watt and a lumen maintenance factor of LM 80. When designing the product, the Ellies engineers underwent exhaustive testing, in both an open warehouse and double volume warehouse typically filled with ing lights are available in a variety of sizes and all come with replaceable LED lamps. They all differ in design too. The round ones have unique elements such as single silver rims, tiered silver rims, and subtle silver rings. There are also designs that are sau- cer-shaped and square-shaped. For more illumination in the room, then semi-flush mount lights are better suited for the task, as the gap between the top of the light and the ceiling allows for light to be reflected off the ceiling while providing direct downward light. This helps brighten the space in its entirety. When it comes to semi-flush mounts, more decorative options are available in comparison to the more utili- tarian flush mount. Height and purpose Now that you are familiar with the difference between the two, it’s time to consider the area in which they will be installed and what that

WHAT TO CONSIDER WHEN BUYING FLUSH MOUNT CEILING LIGHTS

W ith so many lighting designs on the market these days, it’s easy to forget (or neglect) the humble flush mount (or semi-flush mount) ceiling light. It may be the most common lighting fixture in a home, but it should certainly not be overlooked – and for good reason. Flush mount vs semi-flush mount Flush mounts sit directly against the ceiling while semi- flush lights hang down slightly and are usually suspended on a short stem, creating space between the ceiling and

actual shade. While both are great for low-ceiling rooms and small spaces, flush mounts work particularly well as they allow for greater overhead clearance. Because of their close proximity to the ceiling, the chance of dust and insects gathering inside the fixture is decreased, which means they don’t need to be cleaned as often as their lower hanging counterparts. This proximity to the ceiling is also ideal for strategically hiding unsightly marks on the ceiling as they will not be visible once the fixture is in place. While flush mount lights can certainly be decorative

(such as the Clemente C143 and Toleda Brown Orange Square C134), they do tend to be more simplistic and streamlined in design, making them a subtle addition to the ceiling as opposed to a focal fixture. Eurolux recently added several new prod- ucts to its range of ceiling lights. These modern and minimalist flush mount ceil-

BASIC LIGHTING CONCEPTS COURSE BY IESSA

T he Illumination Engineering Society of South Africa (IESSA) has as one of its tenets the advancement of lighting knowledge. To this end a number of lighting courses from basics to Intermedi- ate as well as with those handling specific areas of lighting have been developed. The Basic lighting Concepts, Vision, Lamps and Colour course is designed to provide persons associated with, or entering into the lighting industry with an understanding of basic lighting terminology and techniques. Taking place on 16 and 17 April at NMISA in Pretoria, the course, which offers 2 CPD Points, covers the following: • Eye and Vision • Colour • General photometric units, terms and concept • Light courses and control gear • Luminous intensity, illuminance and luminance measurements

• Luminaire data • Lighting installations and calculations

The above will be followed by an exam.

• Practical colour • Luminaire design
