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. 

The U.S. Department of Energy (DOE) recently issued new energy standards for general-service fluorescent lamps, and the standards go into effect Jan. 26, 2018. The new rules are likely to primarily affect availability of standard 4-foot, 32-watt (W) T8 lamps and some reduced-wattage T8 lamps.

It wasn’t long ago that light-emitting diodes (LEDs) were used primarily in very specific applications, such as indicator lights and exit signs. The deployment of white LEDs for general illumination applications always seemed in sight but out of reach.

In November 2014, ASHRAE published ANSI/ASHRAE/USGBC/IES Standard 189.1, Standard for the Design of High-Performance Green Buildings, Except Low-Rise Residential Buildings.

Last year, the International Code Council published the 2015 International Energy Conservation Code (IECC), a model energy code that states and other jurisdictions can use in whole or part as their energy code. Today, many states base their commercial building energy code on the IECC.
