Baby tank question - T5

[lastlight]

I know bulbs have an overlapping effect with their spread but if you placed more bulbs to either side of those 4 do you think the corals directly under your fixture would get that much more light? T5 shine mostly down without too much spread away from the length of the bulb I think.

Worst case I think maybe towards front and back of the tank they might not get enough but I'd think you should be fine right underneath the fixtures?
