DEWENWILS Plug in Dimmer Switch for Lamp, Table Lamp Dimmer for Dimmable LED/CFL Lights and Incandescent Bulbs, Full Range Slide Control, Dimmer Extension Cord, UL Listed, Black, 2 Pack

I rate this dimmer highly and am happy with the product. The thing to know that doesn't bother me, but might bother some people is that the dimming is not a smooth, even transition from zero to 100% brightness. It might be due to the kind of LED lights I'm using, and I've noticed similar things with LED photo lights with built-in dimmers. Dimmer range from about zero to 70% is about the same brightness. From 70% to 80% the brightness jumps up but is about the same in that range. From 80% to 95% is another bump up in brightness, but similar, and then with a slight boost to the maximum at 100%. So, at least for these lights, it's more like 3 or 4 levels of brightness rather all the subtle, smooth graduations of brightness that would be expected from a dimmer wall switch with incandescent bulbs. But it's no problem for me and the convenience and functionality for the cost is great.

I like the flexibility of dimming all my table lamps at night and this dimmer serves the purpose. The continuous dimming function allows me to fine tune the light setting. There is no buzzing noise and it works especially well for incandescent and halogen lights. Certain LED light bulbs may have problem with this dimmer, one of my older generation LED bulbs flickers at high frequency at the low setting. I don't fault the dimmer, it's just the incompatibility with some of the LED bulb design.

Best for Christmas Tree lights. Easy to turn on and off. No bending down to unplug from an outlet, just put on top of table or somewhere on the tree. Also adjusting the lights to dim of your liking

These dimmers work, but I would note that the first half of travel does nothing. Light comes on towards the end. The action is not as smooth as some other dimmers, but at least led lights do turn off completely.

Just purchase this DEWENWILS Table Lamp Dimmer Switch 2-pack for two living room 2-bulb table lamps. Also purchased LUXRITE A19 LED Light Bulb 100 Watt Equivalent, CRI90, 5CCT Selectable 2700K 3000K 3500K 4000K 5000K, Dimmable Bulbs 4-pack.Dimmer swich clearly dims these bulbs from full low glow to full 200 watts of light. Works great, much better than we anticipated. Like how the dimmer slide switch sits on table next to lamp base. I think the dim range is probably dependent on the bulb, so those with poor performance may want to change bulbs.BTW, these small A19 size bulbs have switchable color K range from yellow to white. So now we can choose between all color options and all lumens, without changing bulbs. . .

I absolutely love these. I now have them on all my lamps. Especially great for bedtime lamps. Can’t recommend them enough!

At 1 1/2 x 1 x 3" it's large for a switch that sits on my table. I bought it to replace an older model by a different maker that made LED bulbs flicker when dimmed. This one is better, has less flicker, but sometimes there is still some flicker whether dimmed or on full bright.Overall it's better but not perfect. Might have to try the Leviton: costs more, but maybe it's a better product. I'll see how well this one ages.

These work wonderfully on my Christmas lights that are way too bright. Yesterday’s lovely dimmer Christmas bulbs are too hard to find. Everything today is obnoxiously bright. This dimmer works so well at bringing their brightness down on a strand of lights I keep lit all night in the bathroom. It makes them cozy and I can go back to sleep without abrupt light. I have them set to a smart plug so I can just ask for them to turn on or off. I still have to manually adjust the brightness, but this is a doable route s paying $50-60 for a (very reliable) Lutron one. I decidedly abandoned the cheap smart alternatives, as they are a headache and poor quality. This dimmer switch is great. I will be buying more.
