Combining full-color RGB spectrum capabilities, adjustable white color temperatures, and seamless wireless Wi-Fi control straight from your smartphone, this smart lamp delivers professional-grade home automation with effortless plug-and-play simplicity.
Crafted under Xiaomi’s renowned smart home ecosystem, the Yeelight smart bulb is engineered to screw directly into any standard household E27 socket operating on AC 220V mains electricity. Measuring a compact 120mm x 55mm and weighing just 0.1kg, it packs advanced microchip and Wi-Fi transmission hardware into a traditional bulb footprint.

Furthermore, efficiency and safety are built into its core architecture. Operating at a low 9-Watt draw, it replaces traditional high-wattage incandescent bulbs while delivering an impressive luminous flux reaching up to 550 lumens in warm white mode. Certified to CE and RoHS standards with an efficient body temperature threshold kept safely below 60°C, the bulb ensures long-term operational stability. Complete with compatibility for both iOS and Android mobile operating systems, the Yeelight app puts total illumination control right in the palm of your hand, making smart home lighting accessible to everyone.
Immersive Full RGB Spectrum & Adjustable Color Temperatures
The standout feature of the Xiaomi Mi Yeelight is its incredible optical flexibility, driven by a dual RGB and CCT (Correlated Color Temperature) design. The bulb can transition smoothly across a massive spectrum of rich colors, offering specialized luminous flux ratings tailored for every hue—ranging from vibrant red (45-75 Lm) and lush green (100-150 Lm) to deep blue (20-50 Lm). This allows users to paint their rooms with light, creating custom lighting themes for movie nights, gaming sessions, or festive gatherings directly through the mobile application interface.
When it comes to functional daily lighting, the bulb excels just as brilliantly. It features a wide adjustable color temperature range spanning from 1700K to 6500K. Lower Kelvin temperatures (1700K-3000K) emit a cozy, amber-tinted warm white glow ideal for living rooms and bedrooms, while higher temperatures (up to 6500K) provide a crisp, daylight-white illumination that boosts focus and productivity in home offices and kitchens. Fully dimmable and equipped with a generous 180-degree beam angle, the bulb distributes soft, even light across the entire room without harsh shadows or flickering.
Wireless connectivity is established instantly via your home Wi-Fi network, eliminating the frustrating need for external gateway hubs, bridges, or specialized remote controls. Once linked through the app on your iOS or Android device, you can control your lighting remotely even when you are miles away from home—ideal for simulating occupancy while traveling or turning off lights left on accidentally. It is a seamless blend of convenience, security, and advanced LED engineering.
