Thanks to its cutting edge tri-colour LED technology, the unit produces superior mixed colours. Each of the 9W LEDs is actually a 3-in-1 lamp, comprised of 3 different coloured LEDs: 3W red, 3W green and 3W blue. This allows RGB colours to be created within each individual lens, so that all 9 LEDs remain on during the colour mixing process. The result is smoother, more even mixed colours, without the distracting multi-colour shadows that tend to appear around objects illuminated by RGB fixtures with single-colour LEDs.
