Working in collaboration with SBL, Facilities upgraded lighting in the two garages under Building 50, resulting in:
1) Better, brighter, and more well-distributed lighting
The existing lighting was recessed in low ceilings, and even at 200 watts, the high-pressure sodium fixtures gave off a dim, uneven, and unsettling orange glow. The new LED lighting has significantly improved atmosphere and visibility in the garages.
2) Energy reduction of 95% (54,700 -> 2,500 kWh/year)
The new lights are 33-watt LEDs with motion sensors, and were installed just below ceiling level, providing better lighting while meeting clearance requirements. The fixtures were adjusted to an appropriate light level, per industry best practice, further conserving energy. Finally, each fixture dims even further until it senses motion nearby, providing additional savings.

LED bulbs can save you money too, especially if you’re swapping out incandescents. LEDs last much longer, use far less energy, produce high-quality light, and are available in a full range of colors, shapes, and styles. As a Berkeley Lab / UC employee or alum, you can get a discount on high-quality LEDs. See article below for more information.
