LIFX Supercolor A21 Smart Light Bulb, 1600 Lumens 100W Equivalent, Color Changing RGB + Tunable White, Dimmable E26, Matter Compatible, Works with Apple HomeKit, Alexa & Google Home, No Hub Required

The LIFX SuperColor A21 is built bigger for a reason. The larger A21 form factor produces a wider 210° beam angle than standard A19 bulbs, throwing light further across living rooms, open-plan spaces, and anywhere a floor lamp or ceiling fixture needs to do real work — not just set a mood. At 1600 lumens with a 100W equivalent output and just 15.5 watts of power consumption, this is LIFX’s brightest indoor bulb ever made. It’s the smart light bulb your main room has been waiting for. Most color changing smart bulbs produce vivid color on paper and disappointing light in person. LIFX SuperColor technology is different. The A21 delivers red at 300 lumens, green at 655 lumens, and blue at 167 lumens — color that’s genuinely bright enough to wash a wall, shift the energy of a room, or set a scene you can actually feel. The full RGBWW spectrum pairs billions of vivid colors with a tunable white range that runs from candlelight-warm 1500K all the way to crisp blue-sky 9000K. CRI 90 means white light that renders skin tones, fabrics, and surfaces accurately — without the washed-out, flat quality that cheaper smart bulbs can’t escape. No hub. No bridge. No extra hardware sitting on your shelf. The LIFX A21 connects directly to your 2.4GHz Wi-Fi network and uses Matter 1.3 over Wi-Fi for seamless, out-of-the-box compatibility with Apple HomeKit, Amazon Alexa, Google Home, and Samsung SmartThings. Setting up with Apple HomeKit takes seconds — just scan the Matter QR code on the back of the manual and your bulb is live in Apple Home instantly. The free LIFX app (iOS and Android) gives you precise control over color, brightness, scenes, schedules, and automations. Group rooms, build lighting routines, explore hundreds of curated themes, or use Music Sync to make your lights react to whatever’s playing. Control from your phone, your watch, or just your voice. LIFX has over a decade of smart lighting experience. The SuperColor A21 is ETL certified and FCC compliant, rated for 25,000 hours of use — roughly 22 years at 3 hours per day — with an estimated energy cost of just $2.05 per year. It fits any standard dimmable E26 socket, reaches 100% brightness in under one second, and operates on a standard 2.4GHz Wi-Fi network with no subscription required. Backed by a 2-year warranty and real customer support, with a cloud infrastructure built with data privacy as a foundation. Screw it in, open the app, and your space is transformed in under two minutes.
