Review: Great dimmer for boat interior lights - I bought this little dimmer to use on my pontoon boat interior lighting project. For my project, instead of LED strips I used single LED marker lights like what are used on trucks and trailers. I installed 6 of them around the inside of the boat. This dimmer works very well with them to give me a wide range of brightness from full on to almost imperceivable if I want it that low. The max current handling capability for the dimmer is 4.8 amps. These LED marker lights don’t even draw a full amp so there’s no danger here at all. The dimmer works by being placed in series with the circuit’s ground side. The instructions don’t say that but as an electrician I know what’s going on inside based on how it is wired up. Well, I didn’t want a hot wire that wasn’t switched also, so in my video you will see that I wired it up so that I push a button to turn on power to the hot leg of the circuit, and then use the dimmer on the ground side to control the brightness. This is not necessary to turn power off because the dimmer does have a positive click to break the circuit. But it leaves the hot leg on all the time and I’d rather break that as well. Also you will see that I placed the dimmer knob and buttons in a switch panel I installed that normally has 12v sockets or USB ports in these locations. If you want to do that, just buy some 30mm blank plugs for these locations and then drill out a 19mm (3/4”) hole in them to hold the switches. It’s tight and kind of hard to install using screwdrivers up inside the plug to work on tightening the nut holding the switch in, but it can be done.
Review: Minimal RF interference - I had been looking for a compact high quality dimmer for panel lights on my experimental airplane. This unit just feels like high quality, will fit right in on my panel, has smooth operation, including the on/off switch, and I like the choice of knobs. This type of control is capable of controlling VERY small LED or incandescent lights and up to its full capacity. I tested it inches from a portable aircraft comm radio and found no RF interference that I could hear.

### ⭐⭐⭐⭐⭐ Perfect
*by K***T on August 24, 2025*

Worked great, have an off-road light on my Harley that I have wired to stay on bright. Sometimes I don’t want them THAT bright. Took all of 3 minutes to put on and now I can set the light like a house light dimmer on the fly
