How to use

Install the ceiling fixture using the slide-lock mount following the included instructions; the design allows quick attachment and removal of the lamp body for maintenance. Connect the lamp to mains power and add it to the Yeelight or Xiaomi Home app to access color temperature, brightness and RGB backlight settings. Use voice control through compatible assistants or control locally with the Yeelight Bluetooth remote or battery-powered smart switch. Configure schedules, scenes and human-centric lighting modes in the app for automated daily light changes.

Usage recommendations

For daytime tasks and increased concentration, set the color temperature between about 4000 K and 5500 K and raise brightness as needed. For evening use and relaxed environments, choose warmer tones around 2800–3500 K and lower intensity to support natural sleep rhythms. Use moonlight or night mode for minimal, non-disruptive illumination during nighttime hours. Keep the layered diffuser in place to minimize dust buildup; when replacement or cleaning is required, detach the lamp body via the slide-lock for safe access.
