LED high mast lighting solution for Tzaneen

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.

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 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.

Cape Town’s Sunstar ‘a beacon of hope’

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.

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- porates old fencing reclaimed from the

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

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 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”. Professor Antonio Paolucci, director

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. Enquiries: +27 11 207 5600

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,
