Gymnasium Lighting in Oakland, CA

Case Study: Boys & Girl's Club — Oakland, CA
Application: Gymnasium Lighting

Improving the quality of light and ambience inside this gymnasium was a high priority for the Boys and Girls Club of Oakland. Not only did LEP cut half the energy cost, but LEP produced more than double the light output.

Replacing existing 470W Metal Halide with 270W LEP luminaires was an easy choice; the change-out dramatically improved the appearance of the gymnasium and created a safe and bright area for kids to enjoy. The installation took the electrician less than a day as the new solution only required 20 LEP luminaires to replace 20 MH fixtures.
