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. 

Solid-state lighting, such as light-emitting diode (LED) technology, promises significant short-term opportunities, notably in the retrofit market. However, many industry stakeholders are concerned about long-term risks LEDs present as they continue to gain acceptance.


GE's Bright Stik, which it bills as a CFL replacement

Today, GE posted a satirical break-up letter addressed to the compact fluorescent lamp (CFL). The company is moving the focus of its consumer lighting business to the light-emitting diode (LED) lamp.

Multifunctional sensors, networked wireless controls accessible from mobile devices, and, yes, light-emitting diodes (LEDs) are trends that picked up steam this year. These interconnected technologies will be transformational for the electrical contractor (EC).

While street lighting improves traffic safety by enabling pedestrians and motorists to see each other, it also contributes to aesthetics. Landscape lighting enhances security and accents special features to create a unique atmosphere for outdoor events.
