Is that a 220/240 Ballast? If it says THAT ONLY, no the input voltage cannot be changed. That looks like a VERY NICE ballast, be careful.

I dont think youd blow the bulb up, but you sure could burn something up or start a fire really quick.......

I assume that all of those parts in the picture are from the ORIGINAL assembly?
