12 volt, 3-channel LED controllers, 2 amps per channel. These are intended for use with IR remote controls, which we don't have. New old stock, these have been kicking around in the warehouse for 2-5 years. No warranty, no returns. You get approximately one pound of controllers (roughly 50 controllers), limit two pounds per customer. We have 40+ pounds in stock and when they're gone, they're gone.
