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 controls save energy by turning off or reducing lighting when it's not needed. The smarter the control and the more flexible the light source, the greater precision in delivering maximum energy savings. Because LED lighting is instant-on and easily controllable, outdoor lighting control now offers higher energy cost savings through flexibility.

According to the U.S. Department of Energy (DOE), about 160 million lamps operated in the building exterior, parking area and roadway lighting markets in 2010. Building exterior made up 39 percent of these lamps, parking 33 percent and roadway 28 percent.


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.
