I am retrofitting some LEDs to supplement the 3x3watt white 2x1 watt blue fixture I have. I am using 3 watt RGB LEDs cree stars so I can program some nice color shows. I can tune the color a bit, I get 1.8 watt of 6k white or 2.1 watt of 4k white. I plan on keeping acans along with some forgiving softies like candy canes, GSP, and frogspawn. Each driver I have can power 4 LEDs. Is an additional 8 watts (19watt total) too much for this small 4g?
