Main and background light - both in colour: The Hue Datura ceiling panel has a diffuse main light and a subtle background light, both of which provide the full range of coloured light. Each light can be controlled individually: The Hue Datura ceiling panel has a large main light as well as an upward shining backlight that can be controlled separately in the Philips Hue app. You can even create a zone to control them together. Frameless design and slim profile: Hue Datura ceiling panels offer a ‘frameless’ effect - all you see is the light. It's a slimline ceiling panel that sits almost flush with the ceiling and blends into almost any décor in your living room, bedroom, kitchen or even hallway. Easy to install: Simply mount the base and hang the Hue ceiling panel from the included hooks to connect it to your home's power supply. Then simply click the panel into place.
