Rated 1 out of 5 by from One to steer clear off I kicked back the cheaper LAP version of this Dimmer because it was a pain to install. I'm wishing I'd stuck with them as these have caused more work and cost than is necessary. Build quality is pretty poor and the back planes are made up of two parts of fairly cheap feeling plastic and are way to pliable for their own good. This makes screwing them up to a good fit against the back box and fitting the equally thin and flimsy cover plates very difficult. Having tried to fit out a large living room with outlets and switches from this range I have had to convince the customer not to go for the screwless look, take the hit on the cost of the various switches and outlets as quite frankly I'm not even sure Screwfix would take them back. And invest a couple of extra hours poly filling around a couple of damaged back boxes. One rather noticeable design fault is that the outer part of the sockets back plane is clear plastic. When set against the wall the cover plate does not touch the wall and the prismatic effect of the clear plastic that is left showing between the face plate and the wall makes it look as if the decorator was having a bad day. Definitely one to be avoided.

Rated 3 out of 5 by from Great dimmer for LEDs Bought 3 of these to replace old leading edge dimmers when swapping from conventional halogens to LED GU10s, they work really really well, ok there's a tiny delay as they feed the power in but that can only mean better life/treatment of the LED bulbs, dimming is very steady, no flicker, no buzzing. My only gripe is that they are supplied with a 32mm screw which, as they are flush / low profile product, means you hit the back of a std 25mm or even 32mm back box before the switch is tight....as box lugs/threads are mostly forward why not supply a 25mm screw instead to avoid this frustration? That is why my overall rating is in the middle which is a shame as the unit themselves are great.

Rated 5 out of 5 by from Finally a dimmer that works Very pleased with this dimmer. I have attempted to locate a dimmer that would work with our transformer operated low voltage lights. And this dimmer works very well. No buzzing sounds at all, regardless of the setting. Very responsive when turning the knob. As mentioned elsewhere, it does have a slight delay when initially turned on. But with our lights, its certainly not an issue. Its about 1/2 second...

Does this dimmer also work with halogen lights instead of LEDs?

Asked by: Willem75
Hello Willem75, thanks for your message. This does work with halogens, up to 300W, but for long term use with halogen lighting we recommend our V-Plus range. Thanks for your interest in Varilight.

LED Compatibilty

Will this dimmer switch work with standard LED GU10 bulbs or do you have to buy dimmable LED bulbs?
Asked by: ceejayibiza
