I've got some pics on my phone somewhere of this plants BEFORE i chopped the bugger in half.
My light is VERY close to the tops of the plants, perhaps 8" bt im experiencing no stoma closure or heat burn due to cutting a whole in the top of the reflector hood over which a powerful centrifugal fan sucks all of the hot air through.

GOOD Light penetration to the sides of the plant would extend down to around 70% or so of its height, but the whole plant is pretty well lit.
