The NLS 20320 is a 40W tri-colour LED downlight rated 240V AC, delivering up to 3600 lumens for high-output general lighting in large rooms and open-plan areas. The 20320 features selectable CCT settings (3000K, 4000K, 6500K) and integrates a dimmable LED driver compatible with standard edge dimmers. A 50,000-hour rated life and IP44 protection suit kitchens, living areas, and covered outdoor ceilings.
Downlights are often undersized in retrofit applications, especially on polishing benches and work areas where general illumination falls short. A single smaller downlight can leave work surfaces dark and strains both eyes and efficiency. The 20320 outputs bright, even light across large ceiling areas, replacing the need for multiple smaller fittings or supplementary task lighting.
Licensed electricians and renovation builders choose high-output downlights like the 20320 for their speed on quoting and install, and for the margin they carry on retrofit specifications. Tri-colour LEDs add flexibility across different room finishes and customer preferences without stocking multiple SKUs. Dimmability is now a standard expectation on the tools, so the built-in driver eliminates the need for an external controller.
The NLS 20320 is not suitable for fully submerged or high-pressure spray environments, or for direct outdoor (non-covered) weather exposure. The IP44 rating is for splash and moisture protection only, not for sustained water jets or complete submersion. Do not install in unroofed or fully exposed outdoor locations.
