Premium Features

Works with what you have.

Works with what you have. But smart bulbs (or Mirrors) are more fun. The LIFX Smart Dimmer installs where your existing switch lives and works with regular dimmable bulbs right out of the box. Smooth, responsive brightness control from day one, no upgrade required. That said, swap in a LIFX SuperColor bulb and the same switch suddenly controls billions of colors, schedules, scenes, and voice commands. Just saying.

Wall control that actually works.

Four customizable buttons, each supporting single press, double press, and press-and-hold. That's up to 12 programmable actions from a single switch, including scenes, routines, and connected devices across your whole home.

You'll always know where it's set.

The built-in LED brightness indicator shows the current light level at a glance. No phone, no guessing. Customize the indicator color and brightness in the LIFX app to suit your space.

Smart when you want it. Simple when you don't.

Connect to your 2.4GHz Wi-Fi and the free LIFX app unlocks scheduling, voice control with Alexa, Google Assistant, and Siri, and full scene and routine control. Disconnect and it still works as a dimmer. No dependency, no downtime.

Built for the whole home.

Matter certified and compatible with Alexa, Google Home, Apple Home, and Samsung SmartThings. Use it to control LIFX lights or any other Matter-certified devices on your network. One switch, every ecosystem.

Fits the circuit you already have.

Three-way compatible, so it works as a standalone single-pole switch or pairs with a second dimmer on the same circuit. Handles up to 500W incandescent and 300W LED loads. Requires a neutral wire and 2.4GHz Wi-Fi for smart features.

Product Q&A

Does the LIFX Dimmer require a neutral wire?

Yes — a neutral wire is required. Without one, the dimmer will not work. If you're unsure whether your wiring includes a neutral wire, open the outlet box and look for it (usually white). If it's not present, consult a qualified electrician.

What is the maximum load the dimmer can handle?

1-Gang: 300W dimmable LED · 500W incandescent
2-Gang: 200W dimmable LED · 400W incandescent
3-Gang: 150W dimmable LED · 300W incandescent

Why are my lights flickering or buzzing after installation?

Step 1: Check that all bulbs are seated firmly and that all wire connections in the wall box are securely fastened.

Step 2: Confirm your bulbs are rated as dimmable. Non-dimmable bulbs are not compatible with this switch and will flicker or buzz.

Step 3: In the LIFX App, ensure the correct load type is selected for your dimmer. An incorrect setting can cause flickering or buzzing at certain brightness levels.

Step 4: Try adjusting the brightness level — flickering or buzzing sometimes only occurs at certain points on the dimming range. Note that setting a minimum brightness level is not currently supported in the app.

What is the warranty on the LIFX Dimmer?

The LIFX Dimmer carries a two-year limited warranty from the date of original retail purchase, covering defects in materials and workmanship under normal use. LIFX will repair or replace a defective product at no charge during this period. The warranty does not cover damage from misuse, accidents, or modifications.

What Wi-Fi frequency does the LIFX Dimmer use?

The LIFX Dimmer connects to your home's 2.4 GHz Wi-Fi network — the same band used by most smart home devices. This frequency is great for wall-mounted devices because 2.4 GHz travels further and penetrates walls better than 5 GHz, giving you reliable coverage throughout your home.

Can I use the LIFX Dimmer with standard dimmable LED bulbs?

Absolutely — the LIFX Dimmer works great with most standard dimmable LED and incandescent bulbs, no smart bulbs required. Just install your favourite dimmable LEDs and enjoy smooth dimming control straight away. The dimmer has an adjustable dimming range, so you can fine-tune the low-end level to suit your preference.
