How tall of a tank will a MH 150Watt work for?

Thanks guys!

I really appreciate your input, especially from people that have tried that setup. Since I already have the light and am buying the tank, I will probably go for the 24” high, 37gallon.

I like the height/look of the 47, but it sounds like I will be pushing my light too thin. The column tanks are narrow so it’s going to be hard to have much liverock “real estate” up high.
