I think the biggest issue people have with "high quality" leds is they run them too strong, its not they are losing color from missing something its they are being bleached by too much intense light.
I've had a MMled since the original group buy and through all the BS spewed about them I had got down on the fixture and kept increasing the power until I was about 90%B and 80%W. Things were starting to lose color and I was ready to throw the fixture away. Then I got a hold of a PAR meter.
Readings were 1650 at the surface, 1400 at my upper rack, 350 at the bottom center and 120 at the edges. At this point is when it clicked for me. I lowered the intensity to get 1200 at the rack and 250 bottom center and 80 at the edges. Then adjusted my corals accordingly acans and chalices to the bottom edges, zoas across the bottom middle and the SPS on the rack. Things have been improving ever since.
The moral of the story is "Know your equipment" there is a lot more to lights than just putting them on a timer. I would be willing to bet a main reason the DIYers have better success is because they know their fixtures better than anyone else.
Back to the OP, I personally really like AI's line and they have A++ customer service. If I were shopping for a new led I'd be looking at the Vega blue, Hydra and the Kessil cannons.
