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.

interesting. I have 3 APC 1400's in my office sitting unused. I think the batteries are dead but if I remember correctly they're less than $20 on ebay. And that's for 2 batteries!
They should have a lot of power, I remember once powering 3 computer and 6 monitors for about 25mins off of an APC 1400. I don't know how that compares to a 55W halogen bulb, but 6 monitors suck a lot of power.
