running 55watt 12 volt fog light off of two 6 volt lantern batteries

[milkshake]

im going dirtbike riding tomorrow and was wondering if i could run a 12 volt 55 watt fog light off of two duracell 6 volt lantern batteries in series. i dont plan on it being a permanent setup but its such short notice im hoping it will have a decent runtime. 2 hours would be great. any input or ideas would be greatly appreciated.

I wouldn't recommend it... I don't think 4-5 amps off alkaline lantern batteries is a sustainable load for them you may find them dimming instantly as the voltage sags under load.

Thanks for the input. I guess I'll just throw a bright flashlight on the handle bars for the day.

If you had a small lead acid battery or a nicad drill motor pack 12-14.4v that should work.
