I run 400w 10k's, and they MUST be acclimated to them and they take a looong time to adjust, But they do.
I can fry them REAL easy, But some of them actually like the brighter light than others. (Red/Orange/greens) The light blues and pinks dont like it so much, But they come around eventually, and perk back up.
Docs indy micro likes the light.
