Bad lighting doesn’t stand a chance against this bestselling home gadget.

The dimmer, currently rated 4.3 out of 5 stars on Amazon, is available in black or white and comes in either a single pack for $13+ or a two-pack for about $25. It features a smooth sliding control that genuinely glides like butter, making it easy to fine-tune your brightness anywhere from 10% to 100% — or completely off (talk about energy efficient!).

I have a lamp on a higher shelf behind a chair that was a pain to turn on and off. I was constantly reaching around furniture or unplugging it altogether. With this dimmer, I finally have an accessible switch right where I need it—no more awkward stretching or fumbling in the dark. As one reviewer noted, you can think of it as a remote for your light.

One thing to note: this plug-in dimmer isn’t compatible with smart bulbs or three-way bulbs. It’s designed to handle bulbs that are 150 watts (or less), holiday lights, or even lava lamps (groovy). In my real-world experience, I haven’t come across a lamp yet that it didn’t work well with.

“I got a lamp with some lightbulb that looked great in the store but were WAYYY too bright in my house. I’m so glad I found this dimmer. Simply plug it into the outlet (I have mine in a smart plug) and plug your light into the dimmer. Adjust up and down with the toggle. Suddenly, my kitchen has ambiance rather than a spotlight shining down from heaven.” —Riley

“It works very well. What a dimmer switch should be. Smooth dimming, no click dial- get the exact brightness you want.” —Mrs. 2024

“Solved my problem! My new LED Christmas tree lights were so bright I could barely look at them - this solved that perfectly. I can dim them to a level that is just right, day or night.” —Amazon Customer

“The TOPGREENER Plug-in Dimmer is basically a mood remote for my lamps. One twist and suddenly my living room goes from interrogation room bright to romantic café glow. Bonus: I feel like a wizard controlling light levels without rewiring anything.”  —DD Gott - Donadees Corner

“The slide control is smooth and works very well - without flickering! Others I tried always caused flickering.” —Z Greg

“Easy solution to a hard to reach switch. Dimmer works well.” —J in Colorado

“Worked great for controlling the heat the bulb in my lava lamp gave off. I backed it off just a touch and it cooled it enough to calm the otherwise erratic flow of the wax inside from being too hot.” —Matt
