In the first U.S. Department of Energy GATEWAY Demonstration in Washington D.C., Royal Philips Electronics Philips of the Netherlands has retrofitted an LED lighting solution for a Department of Labor DOL headquarters parking structure. The DOL and Philips reportedly partnered to install Philips' Vizor LED fixtures in a parking structure below the Frances Perkins building at 200 Constitution Avenue.
The existing 100 watt high-pressure sodium HPS lamps were replaced with the VizorLED units, which have a rated life of nearly seven years and a potential life of nearly 18 years thanks to its proprietary thermal management based on Philips Lumileds' Luxeon Rebel B10 L70. Philips boasts that its VizorLED units are expected to consume half of the energy of the system they replace. Philips points out that using VizorLED, the total watts of the parking structure's test area decreased by 50 percent, from 2565W with a Lighting Power Density LPD of 0.154 100HPS to 1292W with a LPD of 0.077.
