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. 

ASHRAE/IES Standard 90.1 provides states and other jurisdictions a model commercial building energy code.

Recessed housings have come a long way since their initial introduction into the marketplace. Today, more electrical contractors are using low voltage housings to provide task lighting and are including further accents with a full range of trims.

In late 2012, the California Energy Commission (CEC) published a voluntary specification recognizing quality light-emitting diode (LED) lamps intended to replace screwbase incandescent lamps in luminaires.

Linear LED lighting is finding its way into classroom settings and offices.

With an urgent demand for energy efficiency, lighting continues to stake its claim as a solution. T8 and T5 fluorescents—both important evolutions in improved lamps and ballasts—have been landmark offerings. 
Now lighting installers have a new option: linear LEDs.
