Relume Technologies Inc of Oxford, MI, USA, which develops LED solid-state lighting engines and fixtures, and its sales & marketing arm Lumecon LLC of Farmington Hills, MI, have won a contract to supply more than 1000 LED light retrofits to The City of Ann Arbor, MI, USA for its conversion to 100% LED light for its downtown streets.

In October, Ann Arbor became the third city to join the LED City initiative, which was launched last February by the City of Raleigh and LED maker Cree Inc of Durham, NC, USA. The Relume LED retrofit engine is based on Cree’s XLamp LEDs.

“Ann Arbor has chosen Lumecon/Relume to provide LED light engines for all the downtown street lights,” says Lumecon’s general manager Bob Hahn. The contract follows a 25-fixture evaluation that showed a 50% energy savings and 3.8-year payback on initial investment. The fixtures are based on the New Westminster Series made by Lumec Inc, containing Relume LED light engines.

“Lumecon and Relume worked closely with Ann Arbor officials for 24 months to perfect this LED retrofit to the city’s existing globe streetlights. This solution allows Ann Arbor to realize the significant energy and maintenance cost savings and utilize the beautiful globe street light structures already in place,” says Mike Bergren, City of Ann Arbor

assistant field operations manager. “Each LED fixture draws only 56 Watts and is projected to last 10 years. They will replace bulbs that use more than 120 Watts of power and last two years,” he adds.

“This LED project is a giant leap forward towards saving energy and reducing the cities carbon foot print,” claims Hahn. Full implementation of LEDs is projected to halve Ann Arbor’s public lighting energy use and to cut greenhouse gas emissions by 2425 tons of CO2 annually, the equivalent of taking 400 cars off the road for a year. Detroit Edison, Ann Arbor’s local utility provider, will meter the new LED streetlights to gather sufficient information to develop new LED-based tariffs.
