Cylindrical surface-mounted downlight with a powder-coated die-cast aluminium housing. It features an internal polycarbonate ceiling fitting with a bayonet catch and a black plastic ring with recessed LED for lateral glare control. The tool-free interchangeable lens assembly includes a plastic lens (polycarbonate) for optimum homogeneity of the light cone. It offers the best colour rendering with Ra>90, making it suitable for ceiling surface-mounting. Installation is simple due to the separate ceiling fitting with a bayonet catch and plug-in connection. The integrated control gear ensures flicker-free operation and minimizes stroboscopic effects. Accessories can be fitted without tools, including interchangeable optics, decorative lenses, honeycomb louvre, clear and frosted cover discs, and a white plastic ring for replacement.
