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. 

For the ease light-emitting diodes (LEDs) can offer in providing an effective, low-draw and energy-efficient lighting solution, the considerations to their use are many. The best service you can provide is a bit of mythbusting regarding true LED end-of-life.

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.

Walls That Save Energy

Because surfaces and objects in typical spaces reflect light, they can play a part in lighting efficiency as extensions of the lighting system. By controlling room surface reflectances, light levels can be improved, creating opportunities to save energy.

Walk Toward the Light

The green design—good for the environment in that it makes buildings more sustainable—can be bad for lighting, as designers are incentivized to chase points that may require sacrifices to design. For lighting, it can be especially risky.

Lighting on Display

Since the Frank Gehry-designed Guggenheim Museum Bilbao opened in the Spanish city in 1997, crowds of tourists have flocked there. Most say they come to see the museum, hailed as the most important structure of its time. And many stay to shop and eat, generating millions in revenue for the town.

LED: The Hype and the Reality

Noted for their efficiency and flexibility, light-emitting diodes (LEDs) are often billed as the second coming in the evolution of lighting. An exciting work-in-progress may be a better descriptor.
