MERCURYPlug-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.

The media could not be loaded. 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.

Will this work with six ceiling lights

Worked okay for a while, not very smooth min to max then stopped working after a few weeks. Now useless. Dimming ability poor, size is fairly large but as shown, setup is simple plug and play.

Performed well

Perfect for a table lamp, used as a bedroom side-light.Electronic, not resistive, I.E. dimmer = reduced power consumption.N.B. also works with AC motors (e.g. fans) - do not exceed power limit of 300W.White model purchased - cosmetic issue: markings around knob have rubbed off already.Possible premature potentiometer wear: lamp has recently started momentarily extinguishing at the brightest setting, and dimming from ~90% to 70% is a bit rough - repeatedly twisting max to min a few times seems to calm it down 😅

This is just what I wanted to dim the standard lamp.

Purchased this dimmer for my newly bought Mathmos rocket lava lamp which sits on my piano while trying to learn how to play it, but after 3 or 4 hrs the lava tends to be more active than I like due to the constant heat of the bulb. This dimmer allows me to turn down the voltage going to the lamps halogen gu10 bulb which in turn lowers the heat of the bulb so the wax becomes less active and more of a slow moving, mesmerising experience, also the lamp can be on for longer than the recommended 6 hrs that Mathmos says as the bulb isn't as hot prolonging it's life. This dimmer controls the lamp from off to full steplessly. Seems to be of decent quality but the dial feels a bit cheap. Only had a day so can't comment on long-term use but so far so good. Don't know about using it with led bulbs but from previous experience you would have to make sure the dimmer is compatible with led lights. Hope this helps.
