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 February 2014, the U.S. Department of Energy (DOE) announced new energy-efficiency standards for ballasts sold as part of new metal-halide luminaires, which are commonly used for illumination in parking lots, roadways, warehouses, big-box retail and floodlighting. Compliance is required by Feb.

As efficacy, longevity and cost continue to improve, solid-state lighting will become increasingly prevalent. Falling costs have already placed LED solutions at a tipping point for upgrades in several applications in existing buildings, such as in this all-LED retrofit of a Walgreens in Buffalo Grove, Ill.

It’s an exciting time to be in the lighting industry. Today, lighting systems can alter spaces without physically changing them, revitalize urban areas, facilitate interaction and community, communicate information, make spaces more interactive, and affect well being.

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.

When commissioning a high-performance building, one element of lighting control is sometimes left out: the daylight harvesting system. It’s assumed such systems will work right out of the box after some simple calibration. Working is one thing, but working optimally is another.
