I hate my front light!

I currently use one of those Amazon specials that are long, heavy, and with a bar mount that slips all the time despite being tightened all the way (tight, but the weight shifts it on bumps).

I want something that can get very bright with decent reach while lasting at least 4 hours on high mode. It would also be nice if I can get recommended one that has an adjustable angle so I can make little adjustments on the fly.

Budget up to $50 USD. Might be able to stretch that a little higher. Ideally found online through Amazon or elsewhere.
