By replacing the existing HID luminaires, BEKA Schréder has supplied an energy
efficient LED street lighting solution for the entire intersection of the Alzu
Petroport, which is located on the N4 highway, halfway between Middelburg
and Belfast in Mpumalanga.
The primary consideration of LED street lighting is its energy efficiency when
compared to HID lighting. As part of the Trans African Concessions (TRACN4)
initiative to maintain the N4 highway, TRACN4 decided to replace the old HID street
lighting at the Alzu Petroport intersection, with BEKA Schréder’s high-performance
LEDlume range.
The LEDlume-maxi 279 W LED luminaire has replaced the 400 W HID luminaires
on the median, while the on- and off-ramps are illuminated by the LEDlume-midi
144 W, replacing the 250 W HID luminaires. All are mounted 12 m above road level.
An energy saving can be achieved with this retrofit project.
BEKA Schréder’s LEDlume range was chosen as it boasts unrivalled light uniformity.
Also, the required lighting levels for Group A roads were achieved with this lighting
solution.
The LEDlume range is designed and manufactured in South Africa, making it
suitable for the high temperatures found throughout Africa. It sets a new benchmark
in LED lighting with performing and flexible solutions that lead to the shortest payback
time. With its tremendous efficiency, its long lifespan and its limited maintenance
requirements, the LEDlume range allows users to minimise Total Cost of Ownership.
BEKA Schréder locally develops and manufactures LED lighting products, designed
and suitable for local conditions. The company is proud to be associated with TRACN4
and AC Electromech Maintenance Services Middelburg in providing a successful LED
lighting retrofit solution for this project.

GEWISS has launched a range of products – the Smart [4]
LB/HB ceiling mounted luminaire and the Smart [4] FL flood-
light–that take full advantage of the features of LED technol-
ogy to ensure energy savings and optimum visual comfort.
Designed and developed so that lighting systems can
be adapted in a quick, easy and cost effective manner, the
Smart [4] lighting system is multiform, rational, sustainable,
lightweight and versatile and can be transformed from
floodlight to ceiling light, offering different performance
levels for different contexts.
The design aim was to emphasise the typical
characteristics of LED lamps: lightweight, small, practical
and robust. These features were transferred to the end
product, providing it with unequalled performance levels.
The use of power LEDs with high colour performance,
high efficiency optical systems (high bays and lenses) and
availability of multiple configurations make Smart [4]
an ideal solution for minimising costs (for operation and
maintenance) and maximising lighting performance.
The practicality of Smart [4] guaranteesmaximum lighting
performance in any area of application, from industrial to
sports environments, indoor and outdoor. The horizontal
and vertical modularity of the system is combined with
easy installation and maintenance, and the use of ‘green’
construction materials (plastics and aluminium).
The Smart [4] system can take six different optics: four
with rotational symmetry (100°, 60°, 30°,10°), one elliptic
(60° x 120°) and one asymmetric (52 °). In the various
types, the light flux ranges from 2800 to 25 500 lumen
(31°÷ 258°W, loses included). The system can be held in
place in a number of ways: in the plate/spring version, the
body is installed after the plate has been fixed, pressing
slightly to trigger the steel spring; the quick watertight
connector is then used to connect the device to the mains
supply, without opening the power supply compartment.
The entire range is purposely designed and developed to
ensure simplified installation and easy retrofit on existing
systems.

NEW LED LIGHTING SYSTEM FROM MAGNET
THE newly developed MARS LED lighting system, available ex-
clusively from the Magnet Group, has been designed for energy
efficiency and optimum quality of light in commercial buildings,
warehouses and distribution centres, as well as for parkades and
retail installations.
“The new range is based on advanced European technology
and focuses on the principles of ‘Modular,Adaptable,Retrofit and
Serviceable’ to spell out MARS,” says Kaylen Reddy, Magnet’s
lighting solutions engineer and MARS product specialist. “These
high performance fittings have undergone extensive testing in
the Energywise lighting laboratory at Magnet’s KwaZulu-Natal
head office and boast key features that include enhanced
aesthetics, an extended lamp life of over 50 000 hours and heat
tolerance up to 50°C to ensure safe use in harsh environments.
Precise analysis and defined performance parameters during
laboratory testing ensure the highest levels of accuracy in every
aspect of lighting, including design and manufacture. Locally
manufactured MARS LED lighting systems, which have been
designed for easy installation and simple retrofit projects, offer
high quality, low glare light, available in different distributions,
from 30°, 60° to 120°. This customisable range is also available
with dimmable functions and is supported by a five year
guarantee. LED linear strips are designed to slide easily into the
P200 channel, held securely together with magnetic gear. All
the installer needs to then do is connect the power supply. The
modular design of these fittings facilitates the customisation of
lengths, lumen output and wattages to suit every application. An
extruded rail enables easy mounting and replacement of LED
boards and an electronic driver, with adjustable output settings,
ensures flicker-free operation.
Magnet has completed installation of these energy saving,
recyclable fittings in more than 30 Boxer Supermarkets
nationwide. Its team of lighting specialists has extensive
experience in identifying energy saving opportunities and
implementing appropriate eco-friendly solutions to reduce
wasted electricity. Apart from lighting solutions, the company’s
energy saving service incorporates metering, hot water
systems, air-conditioning controls and solar systems. This
project management service has contributed significantly to
the reduction of wasted energy in industrial and
commercial sectors throughout South Africa.
