Well, I'm using LEDs, for the first time mind you, in a 5' tall grow box. It has 3 watt diodes, which I think are about the maximum wattage I can use in such a limited space. I've not had any issues during vegging but, as you stated, after the pots and light rigging, I'm left with 3' of height with which to flower. I'm topping to reduce overall height which should help some. I'm hoping that the ladies can withstand the LEDs closer during flowering than during vegging. I guess I will see over the next two months or so.
CH, you should be just fine. The top of my last plant was about an inch from my MarsII 1200w and had no ill effects whatsoever.
