Varilight LED Dimmer Switch 1G 1/2-Way 300W Slate Grey is rated 4.4 out of 5 by 22.
Rated 5 out of 5 by from good dimmer I read the other reviews before I bought this and can see they are helpful so I would mostly be repeating what other people have said. - Yes there is a slight delay once you click the dimmer on to when the light comes on but you are looking at 1-2 seconds. this is due to the soft start feature. Its not that much of an issue. - I have got a light that uses 5 x G9 3w LED bulbs. Works perfectly fine with them and there is no buzzing from the bulb or the switch unit. - the dimmer switch has a nice feel when turning it on and off. also when adjusting light. The mounting unit I'm not a massive fan of as it is a little "plasticy" but the faceplate goes over this so covers this all up. Once its on the wall it is never coming off so not an issue. overall very pleased with the product. hope this helps in someway.

Rated 5 out of 5 by from Modern and sleek I bought the to replace my existing dimmer that didn't dim the spotlights in the kitchen. The existing back box was too shallow as this dimmer isn't as deep as the old one but after swapping the screws for shorter ones it fits and looks great. It dims my spotlights perfectly!

Rated 4 out of 5 by from Does the job Works well with five SES 5W LED lamps. No flicker. I did not need to set up at all, so cannot comment on this aspect. There is a delay when adjusting, but I don't find that a problem. The face plate was a bit fiddly, but otherwise all is good. Although I have given four stars for reliability, this has to taken in context. It is only a month in use so far.

Rated 5 out of 5 by from Excellent Dimmer I Recently Had All New Spotlights Fitted In My House, With GU10 LED Bulbs. At First, I Had Fitted The LAP Dimmers, Soon To Realise The Bulbs Were Flickering. I Then Changed To These Dimmers And BAM, No More Flickering. Was Abit Fiddly Fitting But Got There At The End....
