SL Fire Vulcan question

[SmokeDiver]

I have a Streamlight Fire Vulcan I am looking to mod with a different bulb. Does anybody know if you can do a kind of ROVF (Roar of the Fire Vulcan)? Can a much higher wattage bulb be used than the standard 6 watt? If so, how would it work with the stock SLA battery pack? Are there any battery packs out there that would perform better driving a higher wattage bulb?

I'm kind of new to tinkering with lights so I apologise for my rapidly rising learning curve.
