How do I know whichs lights will fit this hood?

Okay, so i'm shopping for a hood and actinic lights for my new 20 Gallon Long tank.

This 30 inch long hood looks nice: Perfecto Fluorescent Place-a-Lite Hood Black Aquarium Hoods

It says it fits 24 inch lights. But how do i know if fits a T5 or a T8 or T12? Can I just buy any 24 inch light?

For example, here's a 24 inch T5 actinic light that looks fine to me: Blue Life T5 Pure Actinic Lamp Aquarium T5HO Bulbs . Will that fit in the above hood?

Can almost guarantee thats a T8 fixture. It is not going to be T5 or T5HO. You cannot put a T5 bulb into a T8 lampholder, so they are not interchangeable.
