Remote Control and Dimmer for LEDs EVDRCDDetails: Control your LEDs in a new way! This controller lets you turn on, turn off, or dim your LEDs remotely. The remote has 2 components, a Handheld controller and a receiver wiring harness that you hook to your LEDs. You can hook up to 30 of our LEDs (our Mega LEDs use more power, so the maximum is 20) to a receiver harness. If you want to control more LEDs, you can get additional harnesses and use the same controller.
