A Dinotte XML-3 tail with 4 cell battery pack (240g) has a run time of 5hrs at 50% power. So realistically to get say 30 hrs of runtime, you'll need 6-8 battery packs, and a total weight of ~2kg for batteries. Given the hassle of recharging multiple packs along with swapping mid-ride.
I'm normally a big advocate of battery lights, this is one case where hub power makes a lot more sense.
Yeah, hauling massive battery packs up hills doesn't sound like fun.

Tail lights need a lot less power than headlights, so I think battery powered tail lights are fine, and there are many to choose from. Batteries in my tail lights last for months.
But have at least one dynamo powered headlight. They are very reliable, and I only see high quality dynamo powered headlights on the market.

Thanks for the input, it looks like for the longer brevets it's going to be dynamo power. fietsbob, thanks for the offer but I do already have a decent dynamo headlight. The CYO is not the very best but pretty good, not nearly as bright as some of the battery lights I see, but it gets the job done.
I might just give the Shutter Precision dynamo a try. They offered to give me one for the cost of shipping prior to PBP 2011, if I would write up a review. I eventually backed out, not wanting my brevet season to be jeopardized by an unproven unit.
