Review: I bought this dimmer to use in a new travel trailer. The dinette has 4 LED puck style lights in the ceiling over it which are too bright at times. The wiring instructions are helpful and installation should be simple if you understand 12v wiring and making proper connections. In my case the original on/off switch had only positive wires connected to it so I had connect a negative wire to the nearest light (all the lights have both positive and negative wires) and pull it back to the dimmer switch. This is a good quality dimmer that works smoothly with no flickering. Really happy with it! Supper with nice low lighting is way more enjoyable.
Review: I bought this with a 6 pack of 6 LED puck lights to install in my Cargo conversion trailer to operate on an off grid or plugged in and inverted scenario. I bought a second 6 pack of puck lights so my rheostat currently operates 12 lights and it works well. The rheostat seems to be of decent quality and works well with the lights. The switch has a positive on/off detent and a smooth rotary action through out. The one thing I don't like is the the switch housing can rotate inside the switch plate once installed if the friction nut becomes loose. Not a deal breaker but something to think about when installing. The jam nut needs to remain tight. So far very, very low level of flickering and only briefly while adjusting. I would buy again. Price point out allows 5 stars.

ダウンライトの電気の取り方をシガーのオスにしています。 ポータブル電源のシガーメスに刺すと正常に調光できるのですが、サブバッテリーからとっているシガーメスに刺すと一切調光出来なくつきっぱなしになってしまいます。 なぜなのでしょうか？
