Uh, going to need a bit more info if you want an accurate answer. Of course you can have too much light, but saying 6 inch led of this or that color don't tell us squat. Is it 6 inches with as many Cree3 watt LEDs as you can get crammed together run at full blast? If so, then that's likely too dam much. Are they a few dinky 1 watt Chinese LEDs, then that's probably not too much. What exactly are they?
