Light4U Donar S HE is a compact, high-efficiency fixed downlight designed for ceiling cut-outs from 110mm to 150mm. With a system luminous efficacy of up to 164lm/W and a maximum output of 3250lm, it delivers powerful, low-glare illumination with minimal energy consumption. Ideal for offices, commercial spaces, corridors, and public areas, it offers high performance with low installation effort. As part of the Donar family, it supports visual consistency across different ceiling formats.

Available in beam angles of 15°, 25°, 45°, and 70°, Donar S HE adapts easily from focused to wide general lighting. The luminaire provides excellent colour rendering (CRI>90) and consistent output. You can choose from a range of colour temperatures to match the atmosphere and application. Accessories such as frosted glass, clear glass, or a honeycomb louvre allow for refined beam control and glare reduction. Using a honeycomb reduces luminous flux by approximately 20%. Control options include on/off, phase-cut, DALI, or Casambi. The downlight comes in white, black, or grey. Emergency kit integration and different connection cables are available upon request.
