"I purchased this to replace an old dimmer that was not really suitable for an LED lamp, although it did dim the lamp. The new dimmer is excellent, works over the full range of dim to full, worked straight out of the box and there is no buzzing at all from the dimmer or lamp (unlike the old dimmer where the lamp buzzed). You can change the settings on this dimmer if necessary, although I did not need to. Only been fitted a few days so I cannot really comment on the reliability, but I hope it's as good as the excellent performance."
"I have tried several switches to find one that will work with the Integral LED bulbs I bought elsewhere, but this one works fine. I have three 6.5W dimmable LEDs in an old lamp, my 15yr old MK soft start dimmer wasn't happy without a regular incandescent bulb, nor where two cheaper switches from screwfix. This switch however has solved this problem and is also able to dim a single 6.5W LED. Looking through the instructions highlighted that it is capable of different Leading or Trailing edge modes too. So if it initially doesn't work (default mode1) you can modify it with a sequence of pushes/turns. Reliability has yet to be proven, but review system requires a marking. This is why I have marked it as average. Well chuffed."
"This Varilight dimmer is really ideal for all purposes. I originally puchased it to dim a low voltage light, working on 12volt halogen bulbs powered by a transformer. These work very well and the light turns on and powers up which is particularly pleasant. They are very smooth and adaptable. The only think it will not do is dim undimmable LED lights, but the that is totally impossible at this time."
"I Bought 6 of these due to standard dimmers giving a high frequency flicker to the lights along with a quite annoying humming.
The soft start function is nice however the reliablity has been poor. 3 have failed, 2 with the push switch failing and the other lost its dimming ability. Also beware that their is a noticable loss of brightness to the LED lights when compared to a normal dimmer/switch
The store has replaced all 3 with no fuss so top marks to Screwfix"
