LED Dimmer Knob - Dim up to 6 Amps of 12V LEDs - Easily mount to a panel
Looking for waterproof dimmer knob? We now offer a Waterproof LED Dimmer Knob.
Turn the knob all the way to the left and it will "click" off. Turn the knob clockwise and the brightness gradually increases from 0% to 100%. The best benefit for you: this 12 volt LED dimmer easily mounts to a panel. So all the electronics are hidden away, and you're left with just a tiny knob.
How to mount:
Just pull the pressure-fitted knob straight off, loosen the washer/nut, and attach to a hole drilled in a panel (about 10mm, or 3/8").
Wiring is simple:
Hook up your 12V + and - to the "IN" port, and then your LEDs to the "OUT" port.
Boom! Quick, easy, reliable dimming in one compact piece of next generation solid-state LED electronics.
If you're up for some hacking, and need to fit this in a tight space, you could even de-solder the knob (which is a variable resistor / potentiometer) from the board, attach new wires, and mount it remotely.
New! You now get two knobs: a black & a silver.
You get both for free in the package, so you can
just pop one off and change the style.

Please note, this will work best on a wired power source rather than a small battery. And of course it will work fine on your car battery too, since that is constantly charged by your alternator.
It won't work on a small 23a sized battery (not enough amperage). It will work for just about 45 minutes on a 9v battery, or an 8xAA battery pack (still not enough amperage for long term use).
As with pretty much all dimmer switches, the ground side is switched rather than the positive side. So you must hookup the output ground wire to your LEDs.
Customer questions & answers
Jared Sasser from Chipley, FL
The Dimmer Knob works great but does have one flaw. The threads are plastic and the nut is metal and when I pressed the knob on the dimmer switch it stripped the threads on the switch. That's why I'm giving it a 3 star. Other than that it works perfect.

This was the smallest LED dimmer I could find and it works just as well if not better than others I have tried. I used it with strip lights with no flickering! Will order more.
