Pair with the Rotary Knob LED Dimmer (item# 511123), ProLine Rotary Knob LED Dimmer (item# 511129), or ProLine White or Single Color LED Controller (item# 513115) to control your white or single color LED tape light installations. Using radio frequency (RF) technology, it eliminates the need to run wires from the dimmer/controller to the wireless touchpad to be able to control LED lighting up to 100 ft. away through walls and doors.

Review: Highly recommend - Efficient. Excellent dimmer, no flickering and easy to connect wires.
Review: Works perfectly. Easy replacement for old Armacost LED dimming knob. - I bought this to replace an old Armacost LED dimming knob that had served us well, with heavy daily use for 5 years, but that had stopped turning off completely (even after the click off, the connected LED lights remained on). This replacement has worked perfectly, and was a breeze to install as a replacement. (It has a detachable wire terminal that plugs into the side of the switch, the same as our prior one. I was able to just unplug the previously wired LED tape from the old one and plug it into this replacement without needing to fiddle with the wire connections.)
