I'm going to try one if these on a frag grow out tank. I'm really enticed by the prices. I saw a video on them from Reefapalooza and they seem to have great spectrum range and on the Pros, it sounds like you can dim each channel independently between blue and white on the 50/50's. Does anyone have experience with these? Up until now I was really looking at the AI Primes due to their spectrum coverage. Any thoughts, opinions or ideas?
