The Maestro LED+ is an ideal dimmer for the bedroom and gives you the option for a slow fade to off, ranging from 10 to 60 seconds. Installation is simple since this dimmer switch doesn’t require a neutral wire and can be utilized for both single-pole or multi-location applications.

A single switch can control up to 17 bulbs, and it’s UL-approved to handle mixed loads with different types of bulbs.

This dimmer switch for LED bulbs does not require a neutral wire and can be used with both single-pole or 3-way switch locations. It’s compatible with up to 150W LED or CFL bulbs.

Best for CFL: Legrand Radiant Single-Pole/3-Way Illuminated Light Dimmer


The Legrand Radiant makes a good option if you’re shopping for a CFL-compatible dimmer switch. Compared to other dimmer switches for CFL bulbs, this version supports some of the highest-wattage bulbs—up to 450W for CFL or LED bulbs, and 700W for incandescent or halogen bulbs.

The switch is compatible with both single-pole or 3-way installation options and features a rocker panel to turn the light on or off. A wider-than-expected slider makes it easy to adjust the brightness of your bulbs quickly. This dimmer switch blends into the room, and is available in a variety of neutral switch and plate colors—including options like graphite, bronze, and brushed nickel. 

Best Plug-in: Leviton 300-Watt Tabletop Dimmer

Leviton 300-Watt Tabletop Dimmer

A plug-in dimmer is an easy way to adjust the brightness of bedside lamps or a floor lamp in your living room, without worrying about hardwiring your fixtures and installing permanent dimmer switches. Instead, simply plug the lamp or lighting fixture into a tabletop dimmer, like this version from Leviton.

It’s compatible with incandescent, halogen, dimmable LED, and dimmable CFL bulbs and has a 6-foot cord to reach the closest outlet. A small box on the cord includes an easy-to-use slider that allows you to set the brightness of the lamp at your specified level for either ambiance or energy savings. 

What to Look for in an LED Dimmer Switch

Single vs. multi-room Many LED dimmer switches are only wired to control the lighting in a single room, but others are equipped to change the lighting in multiple rooms with the press of a button. If you opt for a multi-room option, you’ll need compatible dimmer switches in several rooms—and the electrical setup can be a little trickier—but you can set the mood in an instant or bring the lights to full brightness easily.

Control While manual dimmer adjustment (in the form of a sliding lever) is giving way to remote-control and app-controlled options, some people prefer the reliability of using a wall-mounted switch. However, today’s LED dimmer switches make it possible to turn the lights up or down from the comfort of your couch and that's a convenience you may ultimately want.

Smart home features Some dimmers are equipped with the technology to integrate with major smart home systems, including Google Home, Amazon Alexa, Samsung SmartThings, and Apple HomeKit—to name just a few. If you want to control your lighting via your smart home platform, look for a model that's compatible with your current technology platform.
