LED highmast retrofit for Eastern Cape townships
LED designed to
withstand peak
voltages
BEKA Schréder has supplied a cost-effective and energy effi-
cient LED lighting solution for the highmast floodlight retrofit
project in Mdantsane, Dimbaza and Duncan Village, all suburbs
in the Buffalo City Metropolitan area of the Eastern Cape. “With this
project, the Buffalo City Metropolitan Municipality is leading the way of
municipal energy efficiency,” says BEKA’s Peter Badenhorst.
A total of 150 highmasts with 1 000 W HPS floodlights were ret-
rofitted with 470 W OMNIstar LED floodlights, resulting in a signifi-
cant energy saving in excess of 50% per highmast, which ensured
that the project qualified for a 100% energy efficiency funding by
the Department of Energy.
Badenhorst explains that the Mdantsane, Dimbaza and Duncan
Village suburbs are located within the Buffalo
City metropolitan boundary and that Mdantsane
suburb is historically the second largest township
in South Africa run by a single metro.
“Through this project, local residents not only
benefit from their municipality’s energy, and
therefore fiscal, savings, but also through job
creation. The contractor who did the installation
is an empowered local company carrying out the
municipality’s street lighting maintenance and
employs a wide spectrum of local employees,
from electrical artisans to artisan’s assistants,
machine operators, general workers, storemen
and administration staff,” says Badenhorst.
“The OMNIstar is a high-power LED floodlight
and has been designed to provide an unrivalled
combination of performance and flexibility for
lighting areas where high lumen packages are
needed while offering maximum savings in en-
ergy and maintenance costs with a short pay-
back time. With on-site photometric adjustment,
the OMNIstar guarantees the perfect lighting to
ensure safety and comfort. It offers a real alter-
native to luminaires equipped with high-power
traditional sources, with the added advantages
of an LED solution: low energy consumption, im-
proved visibility with white light, limited maintenance and longer
life,” explains Badenhorst. He adds that the OMNIstar can be fitted
with the Owlet range of control solutions to enable further maxim-
ised energy savings by adapting the light levels according to the
real needs of the installation.
“The residents’ response to the new lighting installation was
overwhelmingly positive,” concludes Badenhorst.
BEKA Schréder is proud to be associated with the Buffalo City
Metropolitan Municipality in providing a successful and highly
energy-efficient lighting solution for this significant project.

THE Philips EcoBright LEDbulb delivers high qual-
ity light to ensure direct replacement of GLS bulbs
in indoor applications. The beam of light is free of
infra-red meaning no heat is radiated, and no ultra-
violet light means that fabric and items under this
light won’t fade. The EcoBright LEDbulb offers over
90% energy saving and a longer lifetime of 10 000
hours (equivalent to 10 years if lit 2.7 hours per day
for 365 days).
With load shedding in South Africa, switching
between grid operation and generator opera-
tion generates a voltage peak, which can dam-
age electronic devices and lamps. The EcoBright
LEDbulb is designed to withstand peak voltages
up to 2 000 V, while other conventional lamps
may fail prematurely.
Design highlights
• Form factor is designed as a direct retrofit into
A55 fixtures.
• Long lifetime of 10 000 hours.
• Warm white CCT 3 000 K and cool daylight
6 500 K.
• No UV and no IR.
• Environmental friendly, no mercury or any other
hazardous substances.
• Low carbon footprint.
Application areas
The warm light makes it ideal for general lighting
applications in the retail and hospitality industry
and is suited to shops; corridors, stairways and
washrooms; lobbies and reception areas; hotel
rooms and bars; and residential applications.
