I am trying to do a project in a remote area but I need bright lights. I already have 4 car batteries and 2 tripod halogen worklights from home depot (http://www.homedepot.com/h_d1/N-5yc1v/R-202066789/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053"). Each light is 500 watts so at 120 volts which would be 4.12 amps. Could I hook up these batteries in series to AC lights? I only need light for about 10 mins so I don't need that much juice. Any advice would great, thanks.

I don't know what will happen if you apply DC to those lamps.
They do sell Halogen lamps with 12VDC ratings (automotive purposes). If you want to run 120V lamps, I would suggest an inverter, or a generator with a 120VAC output.
 
I do have an inverter however its only rated to 400watts. Would these bulbs that you sell fit in these lights or is it all new housing. I wouldn't mind buying new bulbs, I was just trying to be resourceful and use what I have.
 
i didnt even think of auto lights, slipped right passed me. I do have a bunch of hellas floating around the garage.
