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.
