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.

The fifth annual Sylvania Socket Survey from Osram Sylvania finds that consumers are adjusting to new legislation and energy-efficient lighting options, with about half saying that they plan to switch to new lighting technologies.

By most accounts, the light-emitting diode (LED) revolution is well underway, even though LEDs still remain a small fraction of today’s total lighting market.

In any lighting system, lamps and auxiliary electrical devices fail and must be replaced. Dirt and dust accumulates on fixture surfaces and should be cleaned. System problems must be corrected, and lighting controls should be adjusted as space conditions change.


It’s hard to imagine anyone in the electrical industry seriously questioning the fact that light-emitting diode (LED) technology and solid-state lighting (SSL) are becoming the light source choice of the future.
