Lighting placement

[StirCrazy]

This is interesting as most bulbs will cover the 2X2 either way, the thing to decide is if you can fit all the lights you want in there with that orentation, I know it would be real tight on my tank to try put them that way, which leads to my question.

my tank is 3 foot long and 2 foot wide.. I am thinking of putting the bulbs parralell with the fron of the tank and have the ends on the outsides of the tanks.. so the glass part of the bulbs will be facing each other.. my thinking on this is that I am only covering 18" long by 24" wide with each bulb so I should have the sides of the bulb to the longer dimension... right?
