deeplove,
I just finished making them for my tank, i will write some instructions and take some pics tonight when i get home from work, its really quite easy, I just used blue computer CCFL tubes (neon lights) and stuck them up in the hood, used a 9v DC transformer cut the plug off the end, cut the molex (computer plug) off the power lead to the neon transformer, soldered em up and bam instant moon light, I also used black electrical tape on 2 sides of the neon to dim it down a bit. It works like a treat. but yeah as i said i'll post some pics etc tonight when i get home...
Cheers,
Kym
