LIFX SuperColor Smart Light 1-Pack - 1600 Lumens

LIFX's brightest bulb. At 1600 lumens, the A21 is a true 100W equivalent with enough punch to be your main light, not just a mood accent. Full SuperColor engine, billions of colors, crisp warm-to-cool whites, and setup in under 2 minutes. No hub, no bridge. Schedules, scenes, and automations all in the LIFX app, with full support for Alexa, Google Home, Apple Home, and Matter.

1600LumensHow bright is 1600 lumens?

As bright as a classic 100W incandescent, the bulb you'd grab when one lamp had to light the whole room. That's twice the light output of a typical 60W-equivalent smart light bulb (about 800 lumens), making the SuperColor A21 the brightest smart bulb LIFX makes.

This 100W-equivalent LED bulb also runs whites from a cozy 1500K to a crisp 9000K, with 16 million colors on top. It scores 90 on the color rendering index (CRI), too, so food, faces, and paint swatches look like themselves instead of slightly off.

Go bright and cool while you finally sort the junk drawer, then warm it down when the movie starts. One color-changing LED bulb handles both.

Smart Light Setup

04 steps

Everything you need to install and style your Smart Light is included in the box — no hub required.

In the box:

  • 1 x Smart Light
  • 1 x User Manual with Matter (or HomeKit) QR Code

You’ll Need:

  • A smartphone (iOS 18.0+ or Android 8.1+)
  • The LIFX app (download from App Store or Google Play
  • A 2.4 GHz Wi-Fi network (Most smart devices require 2.4 GHz. If your router combines 2.4 GHz and 5 GHz, that’s usually fine.)
  • Your Wi-Fi password

Important Notes:

  • Keep your phone near the light during setup.
  • Make sure Bluetooth is enabled.
  • Ensure your phone is connected to the same Wi-Fi network you want the light to use.

Installation

  1. Switch off power at the wall before handling the bulb.
  2. Remove your existing bulb and screw in the LIFX bulb. Use an open luminaire (open fixture) only — do not install in enclosed fixtures.
  3. Make sure the fixture provides sufficient airflow around the bulb for optimal performance.
  4. Switch the power back on. The bulb is now ready to pair.

A few things to check before installing

  • Do not install in fixtures designed for smaller or lower wattage bulbs — this can cause the bulb to perform below capacity.
  • Do not connect to a standard incandescent dimmer or dimming control — the bulb will not operate correctly.
  • Install at least 30cm away from other devices that transmit or receive radio signals where possible.
  • Do not use in outdoor or wet areas — this bulb is for indoor use only, not suitable for dust or moisture.
  • Do not use near ovens, radiators, heaters, or other excessively hot environments.

Tips

  • LIFX connects to 2.4 GHz Wi-Fi only. If you have both bands, check your phone's Wi-Fi details to confirm which you're connected to before pairing.
  • Wi-Fi signal can be interrupted by materials like concrete or mirrors. If pairing is failing, move the bulb closer to your router to complete setup, then relocate it.
  • To factory reset, turn the bulb off and on at the switch 5 times at roughly one per second — not too fast. The bulb will cycle through four colors and stop on white when the reset is successful. Use this to remove the bulb from a network before adding it to a new one.
  • If you change your Wi-Fi password or get a new router, you'll need to reset the bulb and reconnect it through the app as if setting it up for the first time.
  • Allow the bulb to cool before removing it from the fitting — switch off at the wall first.
  • Do not open the device — this will void the warranty. Clean only with a soft dry cloth while unpowered.

Select your device below to get step-by-step setup instructions tailored to your phone. We recommend using the Matter QR code method for the quickest and most reliable connection — you'll find the QR code in your product manual, or printed on the back of your device.

Size and fit

Where does an A21 bulb fit?

An A21 LED bulb screws into the same E26 socket as a standard bulb. It's just a little bigger, at 4.53 inches tall and 2.64 inches wide, which makes it a natural fit for lamps and rooms that need more light.

Floor lamps

Rooms with no overhead light

A lamp is the main source here, so the extra lumens matter.

Room to spare for a bigger bulb, with no squeeze.

A21 vs. A19

Same E26 socket, a little more bulb. Measure first in small shades and tight enclosed fixtures, since the extra size can be a squeeze. It's an indoor bulb, so keep it out of bathrooms and off the porch.

Setup

No hub or bridge. It's a Wi-Fi light bulb that connects straight to your 2.4GHz network through the LIFX app. It's also a certified Matter light bulb, so it works with Apple Home, Google Home, and SmartThings, and it works as an Alexa light bulb, too. Schedules, scenes, and voice control are ready from day one.

Fabulous bulbs, arrived well packaged and fast!

I have at least a dozen Lifx bulbs, so I am obviously a fan. However, the setup process is finicky, and this time it was more finicky than usual. It took me about an hour and many attempts to install these bulbs. Hence my three-star rating.

Easy to set up. Great color selection, good light quality.

So Happy with these lights! I was able to make my own custom perfect color! Not too yellow not too blue. The color is so clean, bright and soothing. With the ability to turn all my lamps on/off from my phone. You can also dim each separately and each lamp can have its own color. It feels like I had a designer in my home to customize my lighting. So extravagant and fun!

A great addition to my LIFX ecosystem. Like all the other elements, I functions very well and produces an almost infinite variety of colours.

Perfect for creating an uplight. The base is stable because of its weight. I'm using it to light and umbrella and create any color I desire.

Beautiful colors and easy to connect, I have all of these a decent amount away from my house and router, and they still connect and update seamlessly.

I love these bulbs and highly recommend them. I’ve installed them throughout my home and have used the plain white bulbs for years with zero issues. I recently started using the color bulbs, and they blow Philips Hue bulbs out of the water.

They are far superior in brightness, super easy to set up, and work very well with Apple Home. Highly recommended.

Do I need a hub or bridge to use this light?

No. It connects directly to your 2.4 GHz Wi-Fi network. The only exception is Matter's home and away features, which need a Matter-enabled hub. Everyday control in the app or by voice doesn't.

Does this support Matter?

Yes. This bulb is Matter-enabled, so you can pair it with Matter-compatible platforms like Google Home or Apple Home in addition to the LIFX app. Note that Matter "home and away" access requires a Matter-enabled smart home hub, and devices with older hardware may not be compatible.

Can this bulb show multiple colors at once?

No. This bulb displays one uniform color or white setting across the whole bulb at a time — but that single color is rendered as a vivid, true-to-life SuperColor, giving you one of the most immersive and saturated single-zone lighting experiences on the market. If you'd like multiple colors shown at once on a single fixture, check out the LIFX Candle or LIFX Tube.

Will this work with my existing dimmer switch?

Not officially — standard incandescent dimmer switches aren't officially supported and may cause the bulb to flicker or behave unpredictably. If you do use one, make sure it's set to full brightness to ensure a steady power supply to the bulb. For reliable dimming, control brightness and color through the LIFX app instead, or pair it with the LIFX Dimmer or LIFX Switch for physical control alongside app access.

Can I use this outdoors or in a damp space like a bathroom?

No. These bulbs are designed for indoor use only and aren't suitable for use under dust or moisture, so they should be kept away from outdoor areas, bathrooms, or other damp environments unless specifically listed as indoor/outdoor rated.

Can this bulb support a wind-down or wake-up routine?

Yes. Using the LIFX app, you can set up circadian rhythm-style routines that automatically shift the bulb's color temperature and brightness throughout the day — warmer and dimmer in the evening to help you wind down, and brighter, cooler tones in the morning to help you wake up.

What is an A21 bulb?

A21 describes the bulb's shape and width. The "A" is the classic rounded bulb shape, and 21 means it's 21/8 inches (about 2.6 inches) across at its widest point. A standard A19 is slightly smaller, and both use the same E26 screw base.

Is this the brightest LIFX bulb?

Yes. At 1600 lumens, the SuperColor A21 is the brightest bulb in the LIFX lineup. Need even more light from one fixture? The LIFX SuperColor Ceiling Lights go up to 5200 lumens.
