Recently, Philips Lumileds announced that Lansing Board of Water and Light (LBWL), a municipally owned utility in Lansing, Michigan, expanded its trial of LUXEON-based street lamps with the addition of six new fixtures illuminated by neutral white LUXEON Rebel LEDs.
Now, the city has 23 LUXEON-based street lights, and LBWL officials are considering a significantly larger pilot to determine whether the 34,000 high pressure sodium and metal halide street lamps in the greater Lansing area will eventually be replaced with LED models.
Lansing's first 17 LUXEON-based street lamps were installed in 2007 to explore the possibility of illuminating area roadways and sidewalks with LEDs in order to reduce energy and bulb replacement costs. The LED light engines used in the fixtures were designed by Midwest Circuits, a Ferndale, Michigan-based manufacturer of LED assemblies for outdoor lighting applications. Public reaction to the initial LED street lights has been positive. In a recent survey, 85% of respondents said the new fixtures have a pleasant glow, sufficient brightness and safe light pattern. The vast majority also said they supported installation of solid-state street lamps in other neighborhoods.
Roger Adsit, LBWL Street Lighting Designer, noted "The 'green' movement is making it important for us to implement environmentally friendly solutions wherever possible, and that includes street lighting," he said "Everything is going well with the LUXEON-based fixtures in this pilot so far, and we are continuing to pursue the possibility of transitioning to LED street lamps over the long term."
it’s known Lansing is among a growing number of municipalities around the world that are evaluating the use of solid-state illumination for street lights to take advantage of various LED cost, performance and technical benefits. These include an energy savings of up to 50%, long LED life, mercury-free construction, and better color rendering that can help improve safety and security by reproducing truer color and sharper detail -- particularly when compared to the yellow light cast by sodium lamps.
