HID Lighting Controller HLC-1e, C.A.P. Indoor gardeners can protect lights and gardens by using this Controller as a high-temperature shutdown by setting the maximum temperature allowed and plugging lights into the outlet - if the maximum temperature is exceeded, the unit shuts lights off. Instead of a shutdown, gardeners can use the Controller as a Heating Thermostat and set the temperature for a minimum low, then plug heating elements into the outlet - if the temperature falls too low, the heating equipment comes on. Whichever function gardeners choose, they will love this affordable unit. Controller comes with remote sensor, is rated for 15 amps at 110 volts, and carries a three-year warranty.
