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. 

In June, The U.S. Department of Energy (DOE) released the full public use files from the 2012 Commercial Buildings Energy Consumption Survey (CBECS). This survey provides a massive amount of data describing the national stock of commercial buildings. How many healthcare buildings are in the South?

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.

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.

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.

The Value Proposition

It’s not often that an electrical contractor has the opportunity to sell a product line that saves a customer time, money and energy; promotes green sustainability; and reduces the load on the nation’s power grid. But that’s what industry observers say LED lighting sources can do.

Lighting fixtures are built around a given light source. In the case of LEDs, this task is more complex because LEDs are sensitive to heat and require special means to transfer it away.
