The Holtkötter Disc ceiling light consists of a round reflector and a light head located underneath. The lamp head emits its light onto the reflector, from where it is reflected into the room. At the same time the lamp head also emits light downwards, whereby the uplight and downlight can be switched separately. Four reflector colours can be combined with three colours for the lamp head. The reflector is available in gold leaf, silver leaf, silver and white. The lamp head is offered in black, matt aluminum and white. A replaceable LED with a colour temperature of 2,700 Kelvin extra warm white is integrated as the light source. It can be dimmed via the existing house electrics with a trailing edge phase dimmer (not included in the scope of delivery).
