L.A. Lighting’s Solution 

Working with MWD’s facility management team, L.A. Lighting set out to deploy an LED lighting system that would not only meet the lighting requirements set by OSHA, but also reduce costs. The solution required selecting the right luminaire for the job and pairing it with a controls plan that would amplify the benefits of LED.

The team’s ultimate choice: L.A. Lighting’s WSE201 LED wraparound luminaire, a sturdy, efficient luminaire with an integrated motion sensor. Commonly used in parking structures, corridors, and stairwells, the WSE201’s optional polycarbonate lens, tamper-proof screws, and wet location rating made it an ideal replacement for the tunnels’ 4-foot, 32W fluorescent fixtures.
 

But what really set the WSE201 apart was its ability to reduce energy costs through the clever use of sensors. For the 23 hours per day when the tunnels are vacant, the luminaires dim to just 20% of full power (drawing only around 5W of power), enough to meet OSHA illumination requirements while cutting excess energy use. When the integrated motion sensor detects movement, the luminaire immediately increases to 100% output for 30 minutes, providing full illumination for workers to pass through the area or perform maintenance.
 

Adding to the WSE201’s versatility, the precise lumen output and dimming behavior of the luminaire can be easily customized, allowing the end user to specify the luminaire’s exact performance depending on the application.
