Light4U Donar M HE is a high-efficiency fixed downlight, ideal for retrofitting existing ceiling cut-outs ranging from 155mm to 215mm. It provides a seamless upgrade without the need for structural modifications. With a luminous efficacy of up to 164 lm/W and a maximum output of 3250lm, Donar M HE ensures optimal light output while minimising energy consumption, with a low-glare option. Great for offices, commercial spaces, shops, corridors, utility spaces, and more.

Available in beam angles of 20°, 30°, 40°, and 60°, it offers flexibility for various lighting applications. The downlight delivers excellent colour rendering (CRI>90) and consistent illumination with 2-step MacAdam binning. Accessories such as frosted glass, clear glass, or a honeycomb louvre allow for tailored glare control and light distribution. Using a honeycomb reduces luminous flux by approximately 20%. Control options include on/off, phase-cut, DALI, or Casambi. Donar M HE is available in white, black, or grey finishes. IP65 version is available on request—for bathrooms or outdoor areas. Different connection cables are available upon request.
