"The instruction book says it's not suitable for dimmable led's, but I'm using this to dim 4x 4W G9 dimmable led bulbs from china and it works perfectly. The combined power is only 16W of my application, which is well below the 40W minimum as the instruction book states, but seems to work fine.
Will have to see about reliability, only ran a few hours so far.
Also, I saw an inductor or something similar through a gap in the plastic, and it seemed to wobble when shaken. Usually these are stuck down to prevent them shaking. So quality could be better. But for the price it's ok."
"Having looked around for a new dimmer switch for my daughter bedroom and was shocked at the price they are now , when I was this one in screwfix I thought for that price I would give it a go , so glad I did easy to replace old one , works good and the best thug is it's a push on and off"
"This is the 2nd time I have bought this dimmer. After reading reviews on other dimmers I was concerned this one would have problems but it doesn't. It's totally silent, dims right down to a glow and after 9 months the first one I bought is still going strong. I used it with three 40 watt bulbs and am now using it with one 50 watt eco bulb."
"I actually used this to control a DIY hot wire cutter via an electronic transformer. I was sceptical that the dimmer would work with the transformer (despite stating it was dimmable!). However, it works perfectly. It is a push on/off switch, not rotary as in the description. For £4.19, excellent value. Recommended."
"Good price. Basic low power push on/off rotary dimmer. Working well with a 50 watt GU10 halogen, on a 2 way wire up. Switch action good, dimmer smooth. Acceptable minimal rf interference generated by its firing circuit. Happy."
"Bought to replace a previous dimmer where the push on/off switch had failed: this one feels like good quality with a decisive on-off action and smooth dimming: better than it's more expensive predecessor."
"I bought this based on the feedback here for my new GU10 led downlighters in my living room. Some reviewers had mentioned that it doesnt hum, but unfortunately its a hit or miss. I bought 3 of them for my living room, 2 of them have a small hum to it, and one of them is silent. As another reviewer said, if you do need a switch which wont hum, with your led downlighters, then do get a trailing edge dimmer switch. If this was used for normal lights, it wouldnt have been a problem. Still for the price its worth it (and you get used to the hum in a few days anyways :P)"
