Energy-efficient LED streetlighting for Cape Town highway intersection

generate energy savings, improve lighting levels and reduce maintenance costs. The great variety of high-performance optics optimises the photometric distribution for each specific application to achieve minimum energy consumption. The LEDlume range offers flexible combinations of LED modules, a choice of cur- rents and dimming options to further maximise energy savings and provide the most cost-effective solution. BEKA Schréder locally develops and manu- factures energy-efficient LED lighting products, designed and suitable for local conditions.The com- pany is proudly associated with the City of Cape Town Energy and Climate Change Directorate in providing a successful energy-efficient streetlight- ing solution for this project.

BEKA Schréder recently supplied the LED street- lighting solution for the N2/M3 intersection at Hospital Bend, Cape Town in the Western Cape Province.This forms part of the City of CapeTown’s LED streetlight retrofit programme. As part of the City of Cape Town’s ongoing En- ergy Efficiency Programme, the old HID streetlight installation was retrofitted with BEKA Schréder’s LEDlume-maxi. The new installation provides an energy saving of more than 50% without compro- mising the required lighting levels. The LEDlume-maxi is the largest of the LED- lume family, a high-performance LED streetlighting range that has been designed and manufactured in South Africa, thus taking the continent’s harsh thermal and corrosive environments into account. The LEDlume range offers optimised photometrical performance with a minimum total cost of owner- ship. It provides customers with the ideal tool to

compare several luminaires and select the one that will be most effective for their particular application. Electric lighting is essential to providing supple- mental light in many greenhouses and is the only source of light for indoor agricultural environments. These lighting systems are extremely expensive to purchase and install, so it is important for growers to select a lighting system that will provide the most effective lighting for their application at the lowest overall operating cost.

The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute has developed a free, easy-to-

use online tool that will as- sist growers to evaluate the performance, efficiency, and economics of a wide variety of horticultural luminaires, typically used in greenhous- es and other controlled ag- ricultural environments. This online tool, called the horti- culture luminaire calculator allows growers to accurately
