It's interesting that the LEDs doesn't seem to have enough light on the 420-450 range compare to the Radium.
Hmm... Interesting food for thought.
I retro'd my BioCube 14 to all CREE LEDs and have had pretty good success with SPS.
I have noticeable rapid growth on Limeade, 2 different green Acros, Montipora Setosa, M. Undata, and my pink Bird's Nest has grown from a 1 inch frag in December to 3" round. Zoas are happy, and misc. softies that are still in the tank grow like weeds.
BUT, the blue Acropora Tenuis frag I got about two months ago has not done as well. At first I thought I was driving the tank too hard with light and possibly bleaching the corals a touch. After dialing that back, the color on all the Acros got better, but the blue seemed to develop a brown skim/algae looking film on most of the frag, even though it has basically doubled in size, though not developed any better color.
Long story short, I'm wondering if the great success with all the various SPS except the blue Tenuis is due to a lack of UV light. Currently the tank is 50/50 Royal Blue (and some Blue) and Cool White 3W CREE driven at .95 amps at 85% with some supporting Green and Cyan.
It could also just be that the Tenuis wasn't in great shape and I'm over-thinking this. But the lack of UV light with these fixtures and the problem with the blue SPS might be related.

At this point, I would only run LED blue to supplement my halide but I will still use VHO actinics
