Mercury Plug-In Dimmer Switch | Adjustable Light Control for Lamps & Fans | Works with LED, Filament Bulbs | UK 3-Pin Mains Socket | Smart Dimming | White

Plug-and-play simplicity. This dimmer switch slots straight into a standard UK socket and gives smooth control over lamp brightness—ideal for filament bulbs and compatible LEDs. No buzzing, no flicker, and the dial’s responsive without being twitchy. Used it with a few table lamps and it handled them well. Build feels solid, and the white finish blends in without drawing attention. Great for setting mood lighting or just knocking the brightness down in the evenings. No wiring, no faff—just works.

This is perfect & has done exactly what I wanted it to do. Made what was a harsh light into a beautiful dimmed ambient light making our living room super cosy.

I have had three of these. They are great and do the job well when they are working.The only problem I have found is that they are a little too delicate electronically and are vulnerable to electrical surges.The first unit I received was faulty on arrival and was kindly replaced by the seller. That second unit was working well until, by mistake, I momentarily plugged a laptop into the 4-way socket board which I only intended to be powering a couple of room lights from. After this, it would only reach about half brightness.I then ordered a third unit which worked fine for about 12 months until one of the two bulbs it was powering blew. This damaged the dimmer switch and it died completely.I would give these dimmer switches 5 stars if they had some sort of self-resetting overload protection built into them, but as they stand, they are very good, but a little fragile.P.S. These units DO have a CE sticker on the back.

Don’t buy unless you’re planning a rave, it just flashes constantly

Tried it on a fully functional Philips E27 8w LED bulb that I’ve been using for a few weeks. Initially I thought great, this is a good product but I noticed after some time that there is flickering at certain light levels which is disappointing. I’m just playing around with the different levels and have noticed no flickering on lower levels of light, so I think it’s a matter of playing around with the settings some more. No noise at all from the light or unit which is nice. Overall I’m happy but I’m not sure how long I’ll keep it if it’s flickering continues.

Bought the dimmer for my son's new 15 watt (tungsten) Ikea nightlight, which was proving far too bright. It dims the lamp to a fraction of the level it was before, so we're very pleased as he's sleeping again.The response from control is very linear. Like many dimmers, if switched on (when set to a very low setting) it needs turning up a little for the lamp to light, and then can be dimmed down a lot more. That said, we've left it set at a very low glow and it comes on every time the lamp is switched on.Things to know that aren't in the product description:-The dimmer is rated at 20 watts minimum (but ours works fine with a 15 watt lamp).-Works with mains tungsten or mains halogen lamps.-You must not plug in a compact florescent lamp unless it's designed for dimming - possibly the cause of the one in Mark Rennie's review dying.-You must not plug in a transformer (low voltage) halogen lamp, again could kill the dimmer.-You shouldn't plug in a low voltage halogen with an electronic transformer, unless it's designed to work with a dimmer - possibly the cause of the non linear control and flickering in N N S Waller's review.- The dimmer has an internal 2 amp fuse.Highly recommended for childrens' nightlights!

I gambled on buying this dimmer control, knowing from other reviews, that the device did not work with everybody's lamps.REVIEW SUMMARYBuild quality feels good, but, INITIALLY it did not work with either of my LED lamps. However just before posting my initially prepared review, I thought the fault I was experiencing may be due to me using an inappropriate light bulb. This suspicion was confirmed by the dimmable controller working perfectly after I change the light bulb I was using in the lamp.To be fair, my final rating is based only on using the dimmer controller with the light bulb sold as "Dimmable" and the dimmer controller's build quality.____________________________________________DETAILED REVIEWI have two LED lamps and will describe how they each functioned separately.LAMP INITIALLY FITTED WITH, STANDARD LED LIGHT BULB- For dial positions within the, "LIGHT FLICKERS ZONE", (see images 1 & 2), using the standard LED light bulb (see images 3.1, 3.2, 3.3), the light flickered at a visibly high frequency, (see first part of video).- For ALL dial positions BELOW the, "LIGHT FLICKERS ZONE", the flickering stopped BUT the brightness was fix dim, as shown in image 5 and NOT of variable brightness.- For ALL dial positions ABOVE the, "LIGHT FLICKERS ZONE", the flickering stopped BUT the brightness was fix bright, as shown in image 6 and NOT of variable brightnessNOTE - My camera's exposure setting was locked the same, between images 5 and 6.Same LAMP THEN FITTED WITH A, DIMAMABLE LED LIGHT BULB (sold as "Dimmable bulb" - see images 9.1, 9.2, 9.3)- NOW WORKS PERFECTLY!From DIMMEST most dimmable position, (dial turned to far left), where the light bulb was completely off,to the BRIGHTEST position, (dial turned to the far right), where the light bulb was at it's brightest,the increase in brightness was smooth and gradual as should be expected, with NO flickering and NO pulsating.So, one more time, for the record, with the correct light bulb, (sold as, "Dimmable bulb" - see images 9.1 and 9.2, 9.3), the dimmer controller worked perfectly.I have no video of the smooth increase in lighting described here, as I did not have the time to take another video, and then blend it into the already created video, to create a single video, (video upload limit here is one video per review);this section of testing actually occurred last, as an afterthought, just before posting what I now know would have been my initially more limited and not fairly representative review, lacking all relevant facts needed for a fair review._ _ _ _ _ _ _ _ _ _ _ _WITH FLAT LED LAMP (Tomshine Led Floor Lamp Remote & Touching Control https://www.amazon.co.uk/gp/product/B082LRF5WP/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1 )- For dial positions within the, "PULSATION ZONE", (see image 7), when using the flat LED lamp light, (see flat LED lamp head in images 8.1, 8.2, 8.3), the light pulsated slowly, (see the second part of video).____________________________________________I hope will be helpful for many of you out there.

This amazing device is brilliant!Our previous floor lamp with a dimmer packed up and we couldn't find another one we liked.This fantastic device actually dims ANY floor or table lamp to suit your mood.For the price we paid it's definitely bargain of the year!

It is important to check the compatibility of the light that you attach to it.

this is quite useless. Sometimes everything working fine, then all of a sudden the light starts flickering, which is dangerous for my light, it can burn it.It is not worth it, there are better ways.

I would like to return the item because we live in Australia and does not work

price is very high considering the low quality

It’s not good at all
