In a lighting system, the ballast /driver regulates the current to the lamps and provides sufficient voltage to start the lamps. Without a ballast to limit its current, a lamp connected directly to a high voltage power source would rapidly and uncontrollably increase its current draw and within a second the lamp would overheat and burn out. At Warehouse-Lighting.com, you can find 1000 watt energy-efficient ballasts for your project, whether it’s residential, commercial or industrial. These high-quality options have all been manufactured with the highest standards for a long-lasting solution. They are affordable, easy to implement, and will last for years.
