they use more power because you usually need more halides compared to less t5,s......say on a 4ft tank you would want 2 x 250w halides while you could easily get away with a 4x 54w t5s.......on a 24" tank you would only need one halide but you could still use the same 4 bulb as before.so its all compared to the size of the area you want to l;ight and how many lights you are running.

im not sure on the comparison between 250w of halide vs 250w of t5 thanks
