Ceiling light Yeelight Arwen 550S — 50W LED, 3500 lm, RGB, dimmable, 55.5 cm diameter, IP50, Wi‑Fi/Bluetooth, CRI 95

The Yeelight Arwen 550S is a smart round ceiling lamp with indirect colored backlight and a slim-profile lampshade. With a total power of 50 W and glare-free surface, it provides adjustable brightness suitable for rooms up to 25 m². The lamp supports adjustable color temperature from 2700 K to 6500 K and RGB ambient lighting. It is compatible with Yeelight and Xiaomi Home apps and can be controlled via voice assistants (Google, Alexa, HomeKit, SmartThings), Bluetooth remote or Bluetooth smart switch.

Advantages

The Arwen 550S combines high brightness and a high color rendering index (CRI 95) to reproduce furniture and surfaces with natural colors. Its dimmable LED module and wide color temperature range enable Human Centric Lighting (HCL) modes, including a moonlight night mode and customizable RGB accents. Installation is simplified by a slide-lock ceiling mount and a layered lamp cover that reduces dust ingress, while the modular design allows replacing only the lamp body for an easy upgrade.

Suitable for

• Living rooms and dining areas up to 25 m²
• Home offices and study areas requiring adjustable color temperature
• Bedrooms where night moonlight mode or warm evening light is desired
• Rooms where subtle RGB ceiling accents are preferred

How to use

Install the ceiling lamp using the slide-lock mount following the included installation instructions; the layered cover reduces the need for frequent cleaning. Pair the lamp with the Yeelight or Xiaomi Home app to access brightness, color temperature and RGB settings. Use the app to create schedules, save scenes or activate HCL modes. For quick local control, use the Yeelight Bluetooth remote or the battery-powered Bluetooth smart switch which keeps the lamp online even when toggled.

Recommendations

For daytime tasks and concentration, set the Arwen 550S to cooler tones (approximately 4000–5500 K). In the evening choose warmer tones (around 2800–3500 K) to support relaxation and sleep. Use moonlight mode for low, non-intrusive night lighting. To preserve lamp longevity, avoid covering the fixture and follow the manufacturer cleaning instructions for the layered cover.
