City of Chandler Purchases 208 LED Lighting Systems

TEMPE, AZ - 08/31/2010 - The City of Chandler, Arizona has purchased 208 solar-powered, LED lighting systems for installation along the Western Canal trail. Until recently, installing AC lighting was not a cost effective option over the three-mile trail. The city obtained a stimulus grant from Arizona Department of Transportation enabling this project.

Each system consists of a 170W solar array with three sealed batteries. STC was able to redesign one of its standard system enclosures to accommodate a third battery thus drastically reducing overall project costs. The controls provide dusk-to-dawn operation of the DC LED lamp fixture. The lamp for the project is a modified Warp 9 from Kim Lighting. All the equipment will be installed on a 5-inch x 5-inch square steel pole. All parts are finished in glossy black. Cem-Tec, a local pole manufacturer worked with STC to provide pre-drilled poles to make installation of the systems move faster for the prime contractor's personnel.

Due to the large number of systems to be fielded, STC designed field test equipment to help minimize hookup errors. A handheld test module which plugs into the system wiring harness has been provided to field technicians. The test unit provides visual feedback on the polarity of the battery and solar array connections.

Other participants in this project were Royal Southwest/Electric, Arizona Lighting Sales and Yale Electric West.

STC has steadily been increasing its presence in specialty area lighting systems. More installations will appear on our website throughout the year.
