LEDs lower power consumption of subway lighting

Energy efficient white LEDs are providing environmentally friendly lighting for a subway in Raleigh, North Carolina, USA.

The Golden Dragon LEDs from Osram Opto Semiconductors will replace 12 metal halide lamps. The LEDs, which were installed in fixtures by the Lighting Science Group, have a longer lifetime and greater efficiency, which will reduce the cost of running the light sources. They will also appear more attractive by providing cool, white lighting with a high colour rendering index.

LEDs are now proving to be a popular alternative to conventional lighting, to reduce carbon emissions and energy consumption. Raleigh is currently working to adopt LEDs across the city, to provide light sources for car parks, tunnels, streetlights, and architectural and accent lighting.
