Bring brightness, beauty, and smart control into your largest living spaces with the Philips Hue White and Color Ambiance A21 High Lumen Smart Bulb. Designed to match the output of a traditional 100-watt bulb, this high-performance smart LED is perfect for illuminating expansive areas like living rooms, kitchens, and open-plan spaces with vivid color or crisp, bright white light. Whether you're creating ambiance for a dinner party or setting functional lighting for daily routines, the A21 smart bulb provides dynamic, dimmable illumination that adjusts seamlessly to your lifestyle.
This versatile smart bulb supports both Bluetooth and Hue Bridge connectivity, giving you flexibility to get started quickly or dive deeper into the full Hue experience. With Bluetooth alone, you can instantly control up to 10 lights in a single room using the Hue Bluetooth app — dim, brighten, change scenes, and adjust color right from your phone. Ready for more? Connect to a Hue Bridge (sold separately) to unlock powerful features like automations, remote control from anywhere in the world, multi-room setups with up to 50 lights, and secure, stable connections that won’t drain your Wi-Fi. The Hue Bridge also enables Matter compatibility, letting you integrate the bulb into your broader smart home system.
With over 16 million colors and a full spectrum of tunable white light — from soft, warm tones to cool, energizing daylight — the A21 bulb is a lighting chameleon. Start your day with the "Energize" light scene, focus with cool white during work hours, transition to soft amber hues with "Relax" at night, or set a 24-hour natural light scene that mimics the sun’s rhythm. All lighting modes are fully dimmable, so you can create the perfect ambiance whether you're hosting guests, reading a book, cooking dinner, or winding down for sleep.
Control your lighting exactly the way you want — via the Hue app, smart accessories like the Hue Dimmer Switch or Hue Smart Button, or completely hands-free with voice commands through Amazon Alexa, Google Assistant, or Apple HomeKit (Hue Bridge required for full voice integration). With easy setup and universal A21 form factor (E26 base), installation is as simple as screwing in a light bulb.
This high lumen smart bulb provides up to 1521 lumens of brilliant white or colored light, making it ideal for spaces where brightness is key without sacrificing comfort or control. With the Philips Hue app, you can also schedule routines, create mood-based scenes, or have your lights automatically dim at night and brighten in the morning.
Whether you're just starting with smart lighting or expanding your connected ecosystem, the Philips Hue A21 bulb delivers both form and function. It transforms your lighting from a static fixture into a dynamic tool that supports your mood, productivity, and well-being throughout the day. From subtle accents to dramatic color effects, this smart light adapts to your home — and your life — with ease.
