DISC LED ceiling light with colour select function, externally dimmable The modern, round DISC LED ceiling light can be used in a variety of ways. Whether mounted as a ceiling or wall light, it provides homogeneous light with natural colour rendering (CRI > 92). It is suitable for general lighting in offices, common areas, corridors and sales areas. In addition to direct light, indirect light can be added to brighten the ceiling. This is done externally via the Dali 2 protocol, just like dimmable lighting. It is also possible to set the light colour to warm white, universal white or daylight using internal controllers before commissioning - Including ballast (Dali-2) - Impact resistance: IK05 - Ambient temperature during operation: - 20 °C to + 45 °C
