Take a look at those "energy saver" MR16's at bulbs.com. Mine puts out the equivalent of 35W with only a 20W draw.
My first test got about an hour and 15 but that was inside at 70 degrees. When I ride home it's not terribly cold but it does get down to maybe 45 or so. Not sure if that will have an effect or not. Just in case, I wrapped the battery in cotton for insulation and taped it up.
I remember reading earlier in this thread about those "energy saver" MR16's (yes, I actually did read this ENTIRE thread, pant, pant, pant...). They sound great. Next time I need a bulb I'll remember those.
Just out of curiosity, how much does your SLA battery weigh? At 2.3 amp hours I'd guess it's also pretty light? And if you remember, how much did the 4.5 amp hour one weigh?
