I went on a limb purchasing this, hoping to install in parallel with a cheap 12 V sticky back LED strip that I attached underneath the awning of my camper. When it is on, it is too bright and when it is off, it is too dark. I needed something in between.The LED strip says it will not work with a dimmer. This is a pulse width module dimmer versus a resistor type of dimmer so in theory, it should work, Viola it does. My switching mechanism to turn it on and off, runs off of a Bluetooth module connected to my solar panel inverter. One time I somehow turned it on when the camper was in storage, draining the battery. The switch has a detent position for the off position so it remains off all the time just in case it gets switched on by accident. It is very easy to turn it all the way down where I can still see around the camper and I’m only drawing 1 watt. At 10 W, almost one amp, I flood the entire campsite with light, which is seldom used that bright. It comes with a small panel and a couple screws to mount. I found it very easy to mount and wire in series with the light.
