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. 

As local government and business owners look for ways to improve efficiency and reduce greenhouse-gas emissions, outdoor lighting has become one of the most practical ways for them to reach their goals.


LED streetlights have the potential to reduce energy consumption by about 50 percent compared to traditional high-pressure sodium lights. According to a U.S. Department of Energy (DOE) survey of governments and utilities, 62 percent of respondents reported using LED sources in their streetlighting.

In May 2016, the DesignLights Consortium (DLC) released Networked Lighting Controls System Specification V1.01. By the end of June, the DLC published a Qualified Products List (QPL) for networked controls. This may have a profound impact on demand for networked controls in existing buildings.

The Environmental Protection Agency (EPA) has christened the fourth Tuesday of every October as national Energy Star Day. This year, the agency marked the holiday by issuing a call-to-action to change out inefficient light bulbs with Energy Star certified bulbs.
