I know, there are those spending millions to blend RGB light to eliminate color separation. I prefer in this case to embrace it, and enjoy the effects. By placing these devices at different angles and distances in relationship to a subject, the effects on walls and ceilings is interesting and painterly (odd word, but fitting.)
Each of these modules includes a 1A driver, 3 Lumileds Rebel LEDs, 25 degree optic and individual intensity control. Just aim and adjust the balance between the colors and dig the results. I chose to use the Red-Orange, Green, Blue combination, as it produces the best whites in blended areas, and can make yellow.
The heat sink is thermally bonded to the aluminum body, while the end caps are Delrin. The little diffuser surrounds are Teflon and produce a nice glow.
The pattern areas will be a combination of mixed light background, or can fade from one color to another. Shadow patterns can be intense, and are magenta, cyan and yellow. The light the three modules delivers is impressive, totaling around 650 lumens total.
