The issue is that this patent is going to harm the growth of LED lighting and innovation. Most small aquarium lighting companies will not want to pay royalties to Orbitec and it's a dodgy patent in many people's opinion. If Orbitec gets the continuation allowed they will be able to control all aquarium LED lighting except for moonlights. I don't think that will be a good thing for the hobby.
it is pretty well established now that LEDs are a viable alternative to other types of light. i don't have time to hunt for lots of information but here's two quick links that show what some people are seeing with LEDs:

And yes, the intensity is there. Don't try to look directly into a high power LED. Way bright. Lot's of PAR readings too and people bleaching and and killing corals with LEDs out there.
I am planning on starting my 48" LED array build soon so you will all see what it does on my 75 gallon mixed reef.
