3x3 would be better 24"x54" would and will also work

I find that side gets better light than below or above the bulb. Alot has to do with your reflector though, most reflectors are designed to have a broader horizontal range.

I vote with Micro. If possible, line up the lamp perpendicular to the length of the grow.

don't forget about penetration, that's what's going to help you yield more denser nugs

Herbal, that is what concerns me the most, I can't seem to understand if light fills a volume or a specific distance. Hope everyone knows what I mean, lol.

Freezerboy, that would be the way to set it up for sure.

if I were to use a 400w I'd go with a 2.5 x 2.5 space and keep the light as close as possible for max penetration

I find I can get maximum penetration w/ one leg up.
