Have they made good progress with these hybrid fixtures? I see one at a lfs that isn't all that great as far as popping out the colors on the corals. I think they run a Phoenix 14k bulb. I love the concept and would really like to test one out sometime.
The idea seems to work for me and as we all know it's more than just light that produces coral color. A Phoenix is a great bulb! Are they running HQI or moguls?
