Varilight V-Pro JQP401W 1-Gang 2-Way Push-On/Off Rotary Led Dimmer 1 x 0-120W (1-10 LEDs)

I couldn't resist the temptation of amending my reviews again and again every time I buy these gadgets, but this time I've decided to re-write and simplify this review just because there are way too many merits to bring out in full details.I first bought these in March 2019 and installed them back in China to dim a few Philips, Osram and IKEA dimmable LED bulbs and they worked flawlessly, and so I would always bring a few back every time when I visit the UK. At the meantime, the soft-start feature feels very classy to me!A nice important feature is that the minimum brightness can be manually adjusted to suit different bulbs. Remember though, as different LED lights come with different circuit designs (i.e. there're no global standards on their technologies), by nature, there would be no such "universal" dimmer for all dimmable lights, e.g. these dimmers aren't normally compatible even with dimmable 24V DC LED strip drivers (unless with other compatible lights connected in parallel).My parents were pleased with these dimmers as they made it possible to set the bedroom lights to very dim levels. Whilst they were initially confused when they saw the lights stepping up and down on switching on the dimmer, I easily fixed this by activating the child lock.I last bought this in June 2022, some 3 years after my first purchase. Been a delight to see them packed in plastic bags rather than paper boxes. Gonna install it in due course.

I'm only giving the product 4 stars probably for no fault of its own. It seems cleverly engineered in that you can calibrate it.Be warned that some dimmable LEDs still give slight buzzing sounds. I don't know enough about the electrics in them to say why. But it seems the more recent the bulb, the more likely not to buzz.As others noted, its clever ramping of power levels can be a turn-off for the impatient. With the bulb I have in there when I turn it on, it ramps up to full brightness for a second, then takes another two seconds to work its way down to minimum brightness if that's what I set it at. This might be good for your bulbs, but if you wanted the lowest light level in order to not be dazzled or in order to be discreet, you might find this a drawback. Imagine you wanted to take a girlfriend back to your pad and not be distracted by your bachelor room. For a couple of seconds your room will be fully illuminated. "WHAT was that I just saw on the shelf?".You can arrive in the calibration mode by accident as I have done by squeezing through the door with trays of food and double bumping the switch. It then goes through a stepped brightness routine. Just let it run through its calibration cycling routine and don't touch it or you could change the calibration.Clever dimmer, might be too clever for its own good.

I've used this and the 2-gang version with LEDs from 3 different manufacturers and they have all worked. I've had to use a couple of the settings but it's easy to do this. The result is a flicker free (yippee) and smooth dimming of the lights. I also like the soft start feature.The setup system involves turning the switch and pressing it on and off but it's well described in the instructions. Just don't rush it and it will work.

Used this to control a single 1000 lumin GX53 bulb (from Ikea). Although it has a lot of tweaks you can make through the programming, I didn't need any of it. I just wired it in and it worked great with the default settings.No buzz, no flickering. I was worried it might not dim sufficiently with just an 11Watt load, but it turns down to a very dim yellow/orange glow. Very pleased with this dimmer and much cheaper than the MK alternative (although the MK does have better styling IMO).

Our lounge is lit with 8 GU-10 bulbs. After numerous cheap halogen bulbs exploding on a regular basis, I decided to switch all of them to dimmable LEDs. Our current dimmer worked to a degree, but flickered on/off at low light levels, so I did some research and discovered this. Worked perfectly out of the box. Comes with 3 modes and adjustable low/high lighting levels but worked just fine on the default settings. Plastic housing feels a tad cheap and I managed to chip it slightly due to carelessness while screwing it in to the wall, but this can be overlooked due to the clearly high quality electrical components within.

Ordered with 10x 4w g9 filament led bulbs. Works perfectly. Worth noting the device is programmable so you can get a full range of brightness and driving modes. At certain points the led flickers a tiny bit but a nudge or the dial sorts it. It's not as good as standard but for power saving LEDs it does the job. The push button is a little spongy for me tho so minus one star. There's also a little delay of a second or so between when you turn on or change the brihhtness. This seems to be a quirk of led dimming and isn't too bad.

Has been good and working well for a year but the switch is now getting stuck when pushed in. I have to turn the dimmer backwards and forwards in order to use the button again. Will be replacing with a better quality switch very soon.

My old dimmer switch had a minimum load requirement of something like 60 watts . Caused a flickering of my ceiling lamps on a sporadic basis. This new controller works right down to 0 watts. It seems to be the solution.
