Bought two packs (so for 4 dimmers). One stopped working, and another has a loose connection and so will stop working if you touch it.

Brilliant brilliant

Perfect for job it was needed on and have one spare.

Cupboard lighting

easy to take apart, just unclips (no screws)mosfet is N308ADyou can find some reviews of similar items on YT (inline led pwm dimmer)this works on about 730 - 750 Hzmax duty cycle is around 90% (with 2 led strips; with one it was only about 76%)i doubt those wires will take 6A, and probably you'd need a heatsink on the mosfet as well when driving hardthe pot has a switch tooI'm using it to drive 2 led strips as wide screen backlight, the dimming is going to come handy

Bought this for under bed LEDs.Works great - there is a slight buzz at certain positions (as with all dimmers) but luckily not at the ~70% I have them set at. Not that it's loud anyway and I probably wouldn't notice it when not right next to it
