Is there really much of a difference? Probably a stupid question seeing as how the T5 is High Output. Is this a newer product or something? I bought a reptisun 10.0 T5 HO With the hood it goes in. Trying to think of a clever way to mount it. I know the 8 inch rule. But what is better? Mounting it directly above adjacent to basking light?, but not blocked by the basking lights dome fixture. Or on the back wall of the enclosure?
