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. 

Lighting technology continues to expand with new products and systems that will benefit commercial and residential markets. Lighting has become smarter and easier to integrate with other systems in homes, buildings and facilities around the world.

Networked lighting controls are intelligent and programmable systems in which devices communicate to enact control strategies.

A new light is appearing. Organic light-emitting diodes (OLEDs) stand where LEDs stood about 10 years ago—promising but expensive. But, as LEDs demonstrated, rapid advances can lower cost and speed up adoption. That’s the expectation for OLED lighting.

High-intensity discharge (HID) lamps, notably metal halide and high-pressure sodium, are widely installed in industrial, retail, and other applications. In recent years, the LED revolution has produced retrofit options promising up to 50 percent energy savings and long service life.

Holding Their Own: Linear Fluorescents Adapt to Today's Lighting Needs

LED marketing can give the impression that digital lighting has left other lighting sources in the dust. Not quite. Linear fluorescents are a case in point. While LEDs have their own merits in light quality, energy draw and controllability, so do many of today’s fluorescents.
