I found a neat site that compares current popular bikelights, complete with beam pattern comparisons, side-by-side slider with power level selector, and output runtime charts! It should be stickied for folks looking for bike lights It's that good. The dude who made this site also has YouTube videos of his reviews too but it's all in Japanese - NangokuCyclist (originally written by subjectivelyatractiv)
Parametrek says that these are the best bike lights in his database.
The Lumintop B01 is a community favorite. It doesn't come with a battery, but you can get one here.
