Excellent For What I Needed It To Do

Reviewed in the United States on June 20, 2023

Verified Purchase

This dimmer is exactly what I needed to add to my Halogen globe lamp. Using the Halogen "dimmable" bulbs for my lamp, this dimmer works fantastic. Reduces the light, eliminates the excessive heat produced by the bulbs and prolongs the bulb's lifetime. Amazing difference in brightness, DOESN'T flicker...at all, large choice of intensities to choose from by using the adjustable switch. It has plenty of length in cord, easy to plug in to wall socket and easy to insert the lamp cord into the plug adapter on the dimmer cord itself. Rich, chocolate brown color, solid and smooth switch which is very easy to slide. Bottom of the switch has rubber grips to keep it from sliding on surfaces.
Such a difference this dimmer has on the lamp's brightness. Last two pictures show the difference between the lamp with and without the dimmer. Highly recommend this dimmer for Halogen lights/lamps. Just make sure the bulbs are dimmable and this dimmer will work wonders.

Excellent. Here's a description of cord, dimmer feature, lights I've used it on etc. I have 5 of these!

Reviewed in the United States on April 30, 2017

Verified Purchase

What a great invention!!! I bought one, and have now bought a total of 5. This is a great way to convert your lamps to dimmable lighting. It's portable, so you don't have to hardwire any dimmers into anything. Just plug it in and there you have it, your current lamp is dimmable. I've used it on table lamps floor lamps plug-in swag chandeliers and so on.

In my bedroom I have my table lamp plugged into it and the dimmer part hidden mounted with double sided tape on my headboard near my mattress; so I can just reach right next to my pillow in the middle of the night and turn the light on to whatever brightness I would like very easily. No cords in the way, they're under the bed. So wonderful!

I also like how the cords are a decent length, so I can plug it in and the still have the ability to use double sided tape mount the dimmer part to the wall, or side table, etc. I think it is well designed.

One thing to note, is that it plugs into the wall like a normal lamp plug would, so you are then plugging your lamp into that plug, so picture the length sticking out from the wall would be equivalent to two plugs plugged into one another. Too bad they didn't design it so you plug it into the bottom facing downward instead of out. No biggie though - I fix this issue by using an extension cord or small powerbar and then just plugging it into that so that I don't have an extended dual-length plug sticking out of the wall. Keep that in mind based on where you're planning on putting it. It doesn't really matter if it's hidden behind a couch or something but if you're trying to plug it into an outlet behind a bookcase that needs to be up against the wall or where it's going to be visible you might want to do the extension cord or powerbar solution.

I really like how the dimmer part is at the other end kind of on its own separate cord from the actual plug that plugs into the wall because it gives more options on positioning the dimmer.

I just think it's really well-designed and super handy and useful and I love being able to add mood lighting and dimmable lighting to any of my current fixtures lamps Etc. It's kind of addictive I've already bought four LOL.

Works with Dimmable LED's perfectly

Reviewed in the United States on October 11, 2016

Verified Purchase

I bought a 100W (equivalent) LED bulb for my desk lamp and quite frankly, it was "a bit much". Needed my sunglasses. Anyway, I needed a dimmer. I did quite extensive research on how to dim LED's (PWM vs. CCR and how CCR dimmers were nearly unobtainable, I considered Philips Hue, etc.) and eventually, coming to the realization that I was indeed on a student's budget and couldn't afford a laboratory-grade variable AC power supply to drive my desk lamp, I bought this.

Part of my final decision was that the bulb reads "Dimmable" on the packet - this means that the bulb is designed to be used with conventional dimmers, and doesn't require specialty highfalutin' digital dimmers. This is key - if your LED bulb does not say Dimmable, I highly suspect this dimmer will not work. What did you expect?

This does produce a buzz but only on the lowest power setting and i have to put my ear literally within two inches of the dimmer to hear it. Also, on the lowest power setting, this does cause a little bit of flicker in the bulb - but none too distracting. Honestly I have found that all dimmable LED's flicker to some extent on all dimmers.

It is a little bit slide-y for my liking (it's relatively easy to push the slider) which to some may be desirable - but some high viscosity polyalphaolefin switch lubricant would do the trick if you are looking for some high-quality damped feel.

Overall a wonderful product, would highly recommend for the price. I expect this works great with incandescent bulbs too.

Don't be like me, and read the listing carefully!

Reviewed in the United States on April 6, 2021

Verified Purchase

This dimmer works great, for what it is. The switch slides smoothly, and the bulb gets brighter or dimmer based on how far you slide it. That's about it, with one crucial exception: This dimmer is for INCANDESCENT and HALOGEN BULBS, which I should have read more carefully. I threw an LED bulb I had into the lamp and sure enough, it worked just fine, with one caveat. Incandescent dimmers make LED bulbs buzz. I was not aware of this, so I went out and managed to find an incandescent bulb from a local shop and have been using that, as the buzzing drove me mad.

So my only complaint is that I didn't read the listing. The product itself does exactly what it claims to, and its only flaw was MY fault. If you want a dimmer for LED bulbs, you need to make sure the dimmer is compatible. This may still work, if you can tolerate the buzzing.

Another thing to note is that LED's don't dim as smoothly or as far as incandescent or halogen. LED's only dim to about 5-10% brightness, and will still glow faintly when at the lowest setting of any dimmer. This is just how LED's are designed.

Used this as a cheaper option for reducing the power and temp of leopard gecko lamp. Works good however shouldn’t be a permanent solution. Slider is easily moved so needs to be checked!!

This is only designed for halogen or incandescent bulbs, but it works perfectly with my LED bulb. But my LED bulb is DIMMABLE- if it wasn't a dimmable-type bulb, it wouldn't work.
