A fixture is the casing of a light. There's not much you can do with a light source alone. There's a suitable Philips Hue fixture for everyone. Every collection consists of various types of fixtures. The Philips Hue Beyond isn't only available as a table or hanging lamp, but also as a ceiling lamp. Do you want to control all of your Philips Hue fixtures with the app? Use the Philips Hue Bridge to do so.
