Unlike traditional LED Par cans that mix single colour LEDs together, these high powered tri-colour versions have 24 LEDs where each individual LED produces any colour. The result is a better colour mixing, a more consistent brightness and a wider coverage of light. Whether you are illuminating a display, lighting a room or making these items a permanent fixture in a nightclub or theatre, they are easy-to-use. You can use the internal programs to set a permanent colour at varying brightness levels or you can select colour scrolls at varying rates. For nightclubs and disco applications, there is a sound-to-light mode and 6 DMX channels for those who want full control of their lighting fixtures.
