AN energy efficient lighting system at the newWomans
luggage outlet at the La Lucia Mall in KwaZulu-Natal,
installed by the lighting division of Magnet, has been
completed.
“This project, which involved the installation of modern
lighting fittings, has resulted in energy savings of approxi-
mately 56% a month,”says Gary Dawson, sales manager,
Energy saving lighting system installed at mall

THE Sistine Chapel in Rome is now
illuminated by a novel lighting solu-
tion fromOSRAM. After 500 years, this
extraordinary piece of art history can
nowbe experienced in unprecedented
quality, bathed in the light of more
than 7,000 LEDs.The installation that
has been put in place over the last
fewmonths is designed to protect the
artworks while enablingmuch stronger
lighting. At the same time, it will use up
to 90% less electricity than the previous
installation.
Dr Klaus Patzak, OSRAM’S chief finan-
cial officer and also responsible for the
Luminaires & Solutions segment, says,
that OSRAMdeveloped an LED lighting
solution that“sets standards in terms
of technological strength, quality and
innovation”.

SUNSTAR, an artwork on top of Cape
Town’s Signal Hill and a shining‘symbol
of hope’for this country’s future, was
switched on for the first time at the end
of November.
The 24 mhigh temporary public art
installation, which uses 22 600 low
energy consuming Pharox LEDs, incor-

The communities in the relevant areas were also involved in deciding on new lighting and they found the OMNIstar to be the most efficient,
says BEKA Schréder’s Johan van Deventer.
LED high mast lighting
solution for Tzaneen
of theVaticanMuseum, says the Sistine
Chapel contains themost extraordinary
works ever conceived by the human
mind and is Michelangelo’smaster-
piece.“Wewant to honour the 450
th
anniversary of Michelangelo’s death by
providing new lighting for his work.”
Supported by the European Union,
the lighting of the Sistine Chapel is a
pilot project with the working title of
LED4Art, supported by the European
Funding Programme for Information
and CommunicationTechnology
within the Framework Programme
for Competitiveness and Innovation
(PSP-CIP). The aimof the subsidy pro-
gramme is to demonstrate new possi-
bilities for LED technology with regard
to energy efficiency and improved
quality of light.

prison on Robben Island where Nelson
Mandela and other political prisoners
were incarcerated.
Designed by Chris Swift, Sunstar
features a tetrahedron in the middle of a
star shape and is illuminated with Phar-
ox LEDs fromNTL Lemnis. The artwork
is a spectacular cohesion of structure
and light and, at night the Illuminated
structure can be seen by passengers on
incoming aircraft, as well as citizens and
visitors to Cape Town from as far as
25 km away.
“The artwork is illuminated at night
without consuming any grid supplied
electricity due to the combination of
energy efficient, high performance and
weatherproof Pharox LED strip lights
with a completely off-grid PV genera-
tion platform engineered Eldo Energy,”
says Francois vanTonder, CEO of NTL
Lemnis Africa.
“As a global leader in the field of LED
lighting since 2005, it pleases us tre-
mendously that Pharox LEDs feature in
this and other artworks. The technology
was selected based on our reputation
for high quality and high performance
LED products with low energy con-
sumption. Our interests lie not only in
bringing excellent LED lighting technol-
ogy to the South African consumer, but
also to contribute meaningfully in the
non-commercial sphere.”
The Sunstar is sponsored by Sun Inter-
national and forms part of Cape Town’s
World Capital Design 2014 initiative
in collaboration with the City of Cape
Town and the Robben Island Fence
Company andTrust.

Magnet’s lighting division.“The
design objective was to harness light
in the most effective way to create
the appropriate ambience in the
shop and to show off the true colour
appearance of leather and plastic
goods.”
This installation encompassed
the replacement of existing low
brightness recessed (LBR) luminaire
technology, with 60W light emit-
ting diode (LED) panel luminaires.
Careful consideration was given to
the quality of the lighting levels –and
an overall improvement of 90% in
lux levels was achieved. A colour
temperature of 4 000 K was selected
to ensure merchandise is displayed in
the most favourable light.
Magnet’s understanding of lighting systems, coupled
with design and installation services, in-house testing
facilities and experienced lighting engineers, ensures
enhanced aesthetics and optimum energy efficiency in
diverse industries.

BEKA Schréder recently supplied LED
highmast lighting for the GreaterTza-
neenMunicipality that met the exist-
ing lighting level requirements while
simultaneously providing significant
energy savings, says BEKA Schréder’s
Johan vanDeventer.
The Department of Energy, in
conjunctionwith the GreaterTzaneen
Municipality, funded the project to
replaceTzaneen’s existing floodlights
on highmasts with an energy efficient
solution.
“This decisionwasmade to reduce
energy consumption, as Eskom is
stretched and under pressure to sup-
ply as it is,”saysVanDeventer.
“The existing luminaires were of the
HID 1kWHPS/T floodlight type and
six weremounted on each 40mmast.
The challengewas tomeet the current
lighting levels at the existingmast
spacing. Several lightingmanufactur-
ers submitted quotes and designs
in the build-up to the project. BEKA
Schréder proposed 6*470WOMNIstar
LED floodlights per mast, reducing
the power consumption from6.45 kW
to 2.82 kW– an energy saving of 3.63 kW
per mast. Due to the fact that there is no
existing standard or recommendation for
highmast lighting in townships, samples
of all manufacturers were supplied to
be installed and tested,”explainsVan
Deventer.“The GreaterTzaneenMunici-
pality approved the OMNIstar as the LED
floodlight of choice,”he says, adding that
the communities in the relevant areas
were also involved in the decisionmak-
ing.“They found the OMNIstar to be the
most efficient, and appreciated thewhite
light of the LEDs.”
The energy savings and the reduction
inmaintenance costsmade the OMNIstar
a viable choice to replace the existingHID
floodlights. A total of 60 OMNIstar LED
floodlights were supplied to complete
the project.
BEKA Schréder is proud of its associa-
tionwith this project and its partner-
shipwith the Department of Energy,
the GreaterTzaneenMunicipality, and
MVMAfrica Consulting Engineers.
