Anyone pulled the Hagen T5 Glo's Apart?

[zum14]

Hey, I was wondering if anyone has pulled the T5 Glo light apart? Ive got 2 of the Dual Lights and was wondering if both lights were run on one ballast or if there seperate? I want to try to individually switch them. Im going to open one up tonight if i can to take a peek. I have a feeling its a no, would be nice though.
