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. 

Crops, of course, have always relied on three things from nature: soil, water, and sunlight. If executives at AeroFarms have their way, though, the future of crop growing will be mesh cloth, small amounts of water, and LED lights.

Replacing the driver


The majority of LED lighting products use an electronic driver that functions similarly to a fluorescent ballast. The driver converts incoming alternating current (AC) to direct current (DC) and drives this current to the LEDs.

For a long time, the lighting industry relied on conventional, legacy light sources and traditional designs. Recent advancements in LED technology, however, have changed the face of the industry in terms of the form and function of luminaires.

Flicker in light sources is an old problem made new again in the LED age. Its effects range from annoying to debilitating, and solving it can be challenging. Even defining flicker is difficult.

LEDs: Their Future is (Really) Bright!

Debate continues about whether LEDs have the output in lumens, the color consistency and the price point to replace traditional incandescent, halogen and fluorescent lamps in high brightness and general illumination applications. Is it finally time to end the discussion?

The Value Proposition

It’s not often that an electrical contractor has the opportunity to sell a product line that saves a customer time, money and energy; promotes green sustainability; and reduces the load on the nation’s power grid. But that’s what industry observers say LED lighting sources can do.

Part of the Solution

Lighting fixtures are built around a given light source. In the case of LEDs, this task is more complex because LEDs are sensitive to heat and require special means to transfer it away.
