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. 

Over the past two years, light-emitting diode (LED) luminaires have begun competing effectively against the fluorescent troffer as performance increases and costs decrease.

Lighting controls are devices and systems that regulate the output of lamps and luminaires. They either turn the lights on and off using a switch or adjust light output using a dimmer.

ASHRAE/IES 90.1 2010, the national energy reference standard, requires building exterior lighting to be turned off and/or reduced when not in use.

Landscape lighting is one of the most artistic lighting design disciplines. Its primary purpose is ambience—to make nighttime spaces aesthetic and inviting. On a more practical level, it can extend the usable hours of a site, facilitate wayfinding, improve safety and provide a sense of security.
