To Buy or Not to Buy: City of De Pere Tests LED Lights on the Claude Allouez Bridge
Aug 8, 2011 It has been reported that the three month testing of the LED lights on the south side of Claude Allouez Bridge in De Pere has come to an end. Now the city will analyze the data obtained for the LED fixtures from four different manufacturers and decide on the final contract.
The traditional light fixtures on the bridge are 250 watts, consume 292 watts of power and last about 24,000 hours, while LEDs are closer to 150 watts and some can glow for up to 118,000 hours. The city has to consider that replacing the light fixtures will require upfront installation expenses in addition to the cost of luminaries themselves. According to assistant city engineer Karen Heyrman, cost for putting a new arm and a new fixture on the bridge is anywhere between $605 and almost $900. Yet the city understands that it will be able to save at least 50% in electricity costs per year and will not need to worry about servicing costs for the 4 times longer period of time than with traditional lights.
