Lighting

 

 

Lighting and controls is a huge, constantly changing, dynamic market. The ELECTRICAL CONTRACTOR lighting editorial listed below keeps current on technological innovations from LEDs, controls, and design to innovations in efficiency by traditional lighting formats. 

Human perception of colors in their environment is dependent on light. As electric light sources have varying spectral emissions, the electrical industry relies on metrics to report, evaluate and predict how colors will appear under different light sources.

According to the U.S. Department of Energy (DOE), more than 360 million troffers (named for a cross between trough and coffer) provide general lighting in commercial building interiors.

Lighting technology has become smarter and easier to integrate wirelessly with other systems. The vanguard of lighting technology, LEDs are brighter, cooler, cost efficient and sustainable with a lower carbon footprint.

Over the last seven years, the LED Streetlight Replacement Program in Los Angeles has swapped more than 80 percent of the city’s 215,000 streetlight fixtures with LED units. To date, energy usage has lowered by 63 percent, saving the city approximately $9 million per year in energy costs.
