ODN bulb?

[leslr]

Hi Finseekers (sorry Funseekers)..
I have a question on overdriving a Flo bulb.
I have an eclipse 6 tank with a Hagan 12" 8w power-Glo bulb.I want to upgrade the lighting but do not have to many choises due to the weird shape and size of the hood. Is it possible to fit a different ballast to overdrive the fitted bulb 3 or 4x ??.My other option is to butcher the hood to try and fit in PC's.
Any ideas would be greatly apprec:).
