Any computer types out there?

I have just replaced the UPS batteries on our servers at work. Each battery tray contains 4 9Ah deep cycle sealed lead acid batteries! Since we replace them annually, they are still in good shape.

I have not been able to find 20W halogens around here. So, I purchased a set of 55W driving lights. I am currently testing the run time using the 9Ah battery and a single light from the set. If this works as I hope, I'll have an awesome base to build my lighting system.

My commute is mostly rural and really need some serious light. Sure hope these work out! I'll post results of the test. Perhaps even some photos as things progress.
