Honestly my experience has been that bike lights are way better with rechargeable Li-ion batteries, and not replaceable AA/AAA batteries. Every time I bought one that took replaceable batteries, they ended up, within a year at most, being incredibly faded and not working well, even with a fresh set of batteries. They get to a point where a brand new battery will work well, but for some reason where the first battery lasted months, the new ones all only last days.
I have no idea the chemistry/physics involved in this. It doesn’t really make sense to me. Maybe rust on the contacts? All I know is that I’ve had this happen numerous times. Whereas my expensive combined light/camera unit with a built in battery has lasted years.
Cooling is very important for LEDs. I’ve seen some cheaper brands skimp on the cooling methods, presumably because it means the product costs less to make, and may force a repeat sale later.

Might just be because that’s more of a feature on the budget side of the market, so they’re also made of shoddy materials in most cases.
