LEDs are more intense and directional than any other source generally. From what I've read, most people that experience bleaching and loss is because they do not do a ramp up/down dimming cycle. I've read from some people that they only run them full-strength for about an hour or two a day, and the rest of the time is ramping up and down.
I've got I think 72 on order for a DIY build, was going to be 96 but budget got in the way. Darn money.
