How big can I go while keeping the same light?

[OCDP]

Can't have anything hanging from my ceiling unfortunately, hence why I have the PVC mod built.

Hah, of course someone asks me to post a picture of the mod just after I delete all my old photos on my photobucket account . Haha... this is the only thing I have that can show you somewhat what it looks like. It comes off the ground , straight up, then the flood lamp is in the middle.. it's pretty basic.



(you can see the PVC on the sides coming up... its not too hard to picture the rest.)

Perhaps I could just make the PVC longer.. but in turn that makes it heavier in the middle, which would eventually lead to a bend in the PVC wouldn't it? Also, the coverage is going to be pretty crappy with this flood lamp mod over a long tank.. I think it will anyways.
