haven't tried these yet, but the price is certainly right! You can get a package if you want, but for two sets of 12 LEDs (10 Blue, 10 White, 2 Green, 2 Red) lens, drivers, dimmers, heat sinks and wires is about $450. I will be giving these a chance when I finally get around to setting up the 90 wave.
