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. 

Occupancy sensors automatically save energy by reducing lighting after a space is vacated. After more than 10 years of tightening commercial building energy codes, they are a staple in new construction projects.

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.

Flattering Light: A New Look at Color


From making clothing look vibrant in a retail store 
to facilitating interaction in offices by properly rendering skin tones, a light source's color quality is an important specification characteristic. For this, we use two metrics, correlated color temperature and the color rendering index (CRI).
