Osram SMART+ Ceiling Cylinder RGBW Zigbee 3.0 LED Ceiling Light 8.5W 550lm 2000K-6500K White

The Osram SMART+ Ceiling Cylinder stands apart from ordinary ceiling lights by combining a sleek cylindrical form with fully addressable RGBW colour and tunable white light, all controlled over Zigbee 3.0. Instead of settling for a fixed colour temperature or a single white shade, you can shift from a warm 2000K glow to a crisp 6500K daylight, or choose from millions of colours to match your mood, activity, or interior style.

• Colour temperature range from 2000K (extra warm) to 6500K (cool daylight)
• 550 lumens output with only 8.5W power consumption – efficient and bright
• Zigbee 3.0 connectivity for reliable smart home integration

In daily use

Mounting the Ceiling Cylinder is straightforward on any standard ceiling junction box. Once paired with your Zigbee hub, you can control it through your preferred smart home app or voice assistant. Set a gentle warm white for morning reading, switch to a neutral white for focused work, or add a splash of colour for movie nights and parties. The 100° beam angle spreads light evenly across the room, while the >80 CRI ensures colours appear natural and vivid. With a lifetime of up to 20,000 hours and 100,000 switching cycles, this light is built for years of daily use.
