Round LED ceiling light Fera with adjustable light colour The surface-mounted downlight Fera provides pinpoint and targeted light - for example above a kitchen unit or an area to be accentuated in the living room. Its round plastic body has a matt finish. Thanks to its understated design, Fera can be combined in a variety of ways. The matt polycarbonate diffuser emits the light directly downwards, and the light colour can be set to warm white or universal white using a small switch behind the housing during installation. The Fera LED ceiling light is also externally dimmable via Dali.
