So, if we have a 2ft. by 2ft. square, being lit by a single halide bulb, how is it brighter when bulbs are perpendicular versus parallel?

IMO it a lot more like 18x30 then 2x2 and you alway
have the soket who block a lot. I have searching in all my catalog for the analys of how the light spread under a MH whitout reflector but I just can't remeber where I view it

it like an egg but with a 'U'shadow in one end of the socket maybe someone have a link to those patern

the reflector to are round only on one side so the other side it notting than a flat refector
if the reflector was round on bothe side like a halogen reflector or the doudle ended one it could be another story .
