Lansing expands trial of street lighting using Lumileds’ LUXEON LEDs

LED maker Philips Lumileds of San Jose, CA, USA says that Lansing Board of Water and Light (LBWL), a municipally owned utility in Lansing, MI, has expanded its trial of street lamps based on its LUXEON LEDs with the addition of six new fixtures illuminated by neutral-white LUXEON Rebels. The city now has 23 LUXEON-based street lights, and LBWL officials are considering a much 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 of Ferndale, MI, a manufacturer of LED assemblies for outdoor lighting applications.

Lumileds says that public reaction to the initial LED street lights has been positive. In a recent survey, 85% of respondents said that the new fixtures have a pleasant glow, sufficient brightness and a safe light pattern. The vast majority also said that they supported the installation of solid-state street lamps in other neighborhoods.

“The ‘green’ movement is making it important for us to implement environmentally friendly solutions wherever possible, and that includes street lighting,” says LBWL street lighting designer Roger Adsit. “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,” he adds.

Lansing is among a growing number of municipalities worldwide that is evaluating the use of solid-state illumination for street lights to take advantage of the cost, performance and technical benefits of LEDs (which include an energy savings of up to 50%, long life, mercury-free construction, and better color rendering that can help improve safety and security by reproducing truer color and and sharper detail – particularly compared to the yellow light cast by sodium lamps).
