Review: First Dimmer to Work! - Having recently decorating our front room we purchased two different halogen 'feature' style light fittings, but both came with quite high wattage bulbs, so really we wanted the ability to dim them when required. Both light fittings supported dimmer switches, but with halogen low voltage lights (the ones with built in transformers), you have to have a compatible dimmer switch. I tried a standard one which we already had and that made the lights strobe when dimmed. I then purchased a dimmer from B&Q which supported 'low voltage' and that made both the dimmer switch and the light fittings buzz...and buzz loudly! I then found this, and it was my final shot at it but thankfully, these worked like a charm. No buzzing and no flickering! I have since ordered a second one for the other light fitting and again, it works perfectly. These switches are a little more expensive, but by the time you've bought two or three cheap versions and found they don't work, you'd have wished you went straight for these! One final note though; if you're wanting to dim low voltage halogen lights you do need to check that the light fitting itself supports dimming...not all of them do. Review: Works with Philips Master GU10 LED but only if you change the mode! - I have started replacing my Halogen GU10 bulbs with Philips Master LED 2700K ones as I believe that Philips have finally come up with a bulb that is virtually indistinguishable from the halogen ones in size, colour and brightness. Only thing is that once you have replaced all the bulbs you will probably find that your old dimmer switches need replacing because the new LED bulbs don't exceed the minimum load (often around 60 Watts). This leads to flickering or a lack of dimming. Enter the Varilight V-Pro series. Now the V-Pro hasn't formally been given the green light by Philips but as Varilight claims that their switches work with Philips LED bulbs I thought I'd give it a go. The default setting for this dimmer switch is to operate in trailing edge mode (not recommended for Philips LEDS). The switch worked, but the bulbs didn't dim down by much from the maximum setting. So I changed to the leading edge mode and they worked perfectly - dimming down to almost nothing. The only minor niggle is that the dimming range is a bit uneven in leading edge mode with a very sudden fall off about half way through the turn. The overall build quality of the switch is great and the dimmer module fitted in my rather shallow 16mm sockets. Given the very reasonable price I would recommend this switch for anyone changing over to LED lights. Just be sure to do your homework! ## Features - V‑Pro dimmers are our flagship range — designed for modern LED lighting and built to deliver seamless, flicker-free dimming V‑Pro makes lighting control effortless and elegant - 1-Gang dimmer for a single circuit of LEDs with super versatile V-Pro technology — the industry standard for smooth, reliable dimming - The White Plastic finish offers a clean, minimalist look that blends seamlessly with any interior - These dimmers do not require an earth connection, making installation simple and straightforward.

I think turn/twist on/off is a better design than push on - they often come on on full power, as left, which obviously shocks the light and often kills them (especially filament bulbs). But, it says these have 'soft start' and you can push them on with your shoulder when your hands are full. But, I'd rather have instant turn/twist on dimmers without the soft start delay. Turn on low load (10w minimum) don't seem to exist (cheaply). :( **Q: What depth of wall box is required to mount this dimmer switch?** A: 25mm wall box would be adequate depth for the wall box to fit the JQP401W **Q: I have 4 5w LED bulbs(2 trafos in between), set in mode 3, dimming part is working, but regularly the lights start flickering, what can I do?** A: You need two things to dim LED lighting - 1) a 'trailing edge' LED dimmer - not a conventional dimmer (these have 'Leading edge' dimming, which is no good for LED) 2) dimmable LED bulbs (or dimmable LED bulb+transformer combination) If either of these is missing the LED bulbs will not dim properly and may well flicker too. **Q: Can i use this with a standard bedroom light socket?** A: Hi Dafydd,Yes you can replace your ordinary light switch with this dimmer and replace your normal bulb with an LED or low energy lampin the same lampholder. I bought a Varilight dimmable low energy compact fluorescent to go with it, but found it to flicker at somebrightness settings. I tried all the possible settings on the dimmer to no avail. It may work better with an LED lamp, but I don't have any to try it with.Regards,Paul G ## Customer Reviews ### ⭐⭐⭐⭐⭐ First Dimmer to Work! *by A***7 on 4 December 2013* Having recently decorating our front room we purchased two different halogen 'feature' style light fittings, but both came with quite high wattage bulbs, so really we wanted the ability to dim them when required.
