HID Lighting Controller Delay HLC-2e, C.A.P. This controller will save your lights. If lamps are turned off, then back on again before cooling, as in a power outage, it is called a hot start, and it reduces lamp performance and lifetime.

Gardeners can also use this controller to delay other equipment from starting. Great protection for any indoor gardener. Unit is rated for 15 amps at 120 volts. Controller carries a three-year warranty.
