Varilight 1 Gang 2-Way Push-On/Off Rotary Dimmer Switch HQ3W White Plastic 1x 60-400W

Bought two of them and installed them in minutes. All good. I did remove the adjusting knob to tighten the retaining nut by a half turn, but no problems with the operation of the units and they do fit alright on a shallow pattrice as long as the wires are routed either side of it and there are no bunched up wires behind it.

Easy to fit and works well. These devices need a load to work well so make sure you put at least a 60 watt bulb in the lamp holder. I am very pleased it doesn’t dim the bulb completely out so it reminds you to turn it off. Very pleased with the results.

If you know how to wire light switches then this is an easy fit, the plate protrudes slightly from the wall compared to normal switches, but they work well enough... the one problem I've found is that if you turn the knob slightly too hard you can rotate the base position of the knob so that it ends up with an "off" position if you turn the knob far enough - I'm tempted to take it apart and see if there's something to tighten to keep it in place

Straightforward installation (admittedly I'm a retired electrical engineer!), using the two plate screws provided. Is two-way (Comm, L1 & L2 terminals). Using it only as a one-way, single light switch replacement for two very bright LED (dimmable) ceiling lights I have. They only dim to about half-way, but I think that's normal. I don't need any more adjustment than that.

It buzzes very slightly which is quite annoying - but quality is fine and it works ok.

Now I knew nothing about rewiring switches before starting but this was incredibly easy. Two wires straight into the back. I've had it now for a few weeks with no faults or issues. The switch does make a slight humming noise when it's on which I assume is normal but it's never noticeable unless stood immediately next to it. So overall I'm impressed

A high quality dimmer switch, very good value, a bargain and it is just as good as those you can get in expensive DIY shops. Before I bought this one from amazon I checked out several others which cost a lot more. It is easy to fix, quality white plastic, easy to fit and put on and off, would recommend

For the price they are good easy to fit. Dimmer switches have gone very expensive theses are very good 👍👍
