I just aquired a 120g that is 24" wide. I have 2 MH/PC fixtures that fit perfectly across the top of the tank. Does it matter if the lights are lateral instead of horizontal on a tank?

You may not get sufficient light coverage along the length of your tank, but orienting them laterally may allow you to set up a neat dawn/midday/dusk effect by having them turn on/off sequentially.
