How Many T5 Lights

[Dan-CR4]

Im ordering a new tank in the new year from NDaquatics and wanting to know how many t5 I will be able fit in the hood, its going to be 18" wide. I know how long tubes need to be length ways, but how many do you thing i could fit in, I would like 4 but at the very least 3.

hope i have explained it correctly

Would depend on the internal dimensions of the hood. Would also depend on whether you wat to fit individual reflectors, the size of the light end fittings, etc.
