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. 

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.

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.

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.

Nearly There: Screw-In LEDs

The stakes are high. According to U.S. Department of Energy (DOE) estimates, nearly 1 billion 60W A19 lamps will be installed in the United States by 2010. America is calling for a super-efficient lamp and has pinned its hopes on solid-state lighting.

What's In a Name?

In recent years, ballast manufacturers have begun marketing a premium fluorescent ballast called a “high-efficiency ballast” for operation of 4-foot T8 lamps. A high-efficiency ballast provides the same level of light output as a standard electronic ballast but does it with 2-–5 fewer watts.

CBD Extended to 2013

The Energy Policy Act of 2005 created the Commercial Buildings Deduction (CBD), an incentive consisting of an accelerated tax deduction rewarding investment in energy-efficient interior lighting; heating, ventilating and air conditioning/hot water systems; and building envelope.

Lighting Through the Ages

Starting around age 40, a person’s ability to see gradually diminishes. Statistics estimate one of the 78 million U.S. baby boomers turns 60 every seven seconds. These statistics verify the projection that half the U.S. population will be older than 65 by 2032.

Out of Sight, Out of Mind

When installing recessed fixtures, carefully consider the location of the units. The presence of combustible materials surrounding the luminaire is very important, and recessed lights can act as chimneys for heat loss and moisture transfer into attic spaces.
