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 market for light-emitting diode (LED) products and technology is more attractive than ever because of energy-conservation concerns and lower maintenance costs. Until now the cost wasn’t attractive enough for broad appeal. 


Looking beyond the apps


In the not-too-distant future, 
a time may come when electrical contractors will entertain their grandchildren with tales of lighting fixtures that existed for the sole purpose of illumination.

While the light-emitting diode (LED) has gotten a lot of attention in recent years, another revolution has quietly developed in the background: intelligent (digital) lighting control. The future of lighting is solid-state, and it will be highly controlled.


Dimmable lighting control has seen limited application in commercial buildings. However, due to two primary factors, adoption has grown.

Taking Stock

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?

A Shakeup For T8

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.

LEDs Under Control

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.

Meet The New Code

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.

In the Driver's Seat: LED Drivers

The LED driver acts as a power supply for LED modules, regulating output voltage or current for the light source. It transforms and conditions incoming power (typically AC, but it may be DC) and drives the current to the LEDs.

Safety Check: Lighting retrofits


According to the U.S. Department of Energy (DOE), in 2010, more than 75 percent of lighting systems installed in the commercial building sector were fluorescent, with the majority installed in recessed troffer luminaires.
