I want to make a battery powered mad scientist lamp. Answered

I will be using 4 25 watt bulbs and would like some advice on what to use for a battery.  I am ok with it being quite dim, I need the batteries to be rechargeable and the lamp only needs to operate 3 or 4 hours at a time.  Any advice would be appreciated.


Tr y using filament car lights instead of mains ones., and a 12V battery,.
