LIFX SuperColor A21 Smart Light Bulb — 1600 Lumens, RGB + Tunable White, Matter Ready

Bright, room-filling color with flexible white tones

The LIFX SuperColor A21 is built big for a reason: a 210-degree beam angle that projects light across living rooms, open-plan spaces, and ceiling fixtures where real work gets done. With 1600 lumens and a 100 W equivalent, this bulb provides powerful illumination while keeping power use efficient at 15.5 watts. The color system spans billions of shades in RGB with a tunable white range from candlelight warm 1500K to clear daylight 9000K, all while maintaining color accuracy with a CRI of 90. It’s designed to transform a space, not just set a mood, delivering true color and depth to walls, fabrics, and art.

Smart lighting should feel natural. The SuperColor A21 supports a breadth of moods and activities through the LIFX app, with Color Blends, Gradients, and designer Themes that include Golden Hour and Movie Night. Create personalized scenes, schedule tunable white lighting to match your daily rhythm, and let lighting adapt to your routine. When music plays, you can even sync your lights to the beat for immersive experiences without any extra hardware.
