Yeelight MercuryE C300 ceiling light with presence sensor

Yeelight MercuryE C300 brings smart, comfortable lighting to hallways, entryways, staircases, or a covered porch. The Smart Motion & Light Radar technology reacts to motion and low ambient light, so it illuminates only when needed. The flicker-free 4000 K light is gentle on the eyes and meets IEEE standards for maximum visual comfort.

The advanced Advanced DualSense Auto-Lighting system activates the light when ambient light is below 40 lx and automatically turns it off after 20 s of no activity. A detection range of 1–5 m ensures reliable operation in different scenarios. The robust design with IP44 protection resists dust, moisture, and insects.

• Energy-saving operation – automatic on/off saves up to 30% energy.
• Wide application – interiors and covered exteriors (entrances, porches, gazebos).
• Brightness and efficiency – 1300 lm luminous flux for an area of about 10 m².
• Long lifespan – up to 50,000 hours of worry-free use.
