Q: How log is the burn time on high setting?

Burn time in the high mode is irrelevant since it ramps quickly down to the 1000 lumen med level. Burn time in the med. mode is right at 2.5 hrs. with the 4000mAh 21700 Sofirn battery.

Q: Does it get pretty hot while not underwater?

I have both the Gen 1 and Gen 2 version. The Gen 1 stays cool on high (didn't go over about 95f), but it does have a stepdown. The Gen 2 when on high and out of the water climbed to 125f within 2-3 minutes, which is pretty uncomfortable to hold.

Q: How long does it take to charge the 21700 battery?

Depends on your charger. It’s a 4.0A Battery and comes with a 0.750A/hr charger. You aren’t suppose to store these batteries over 80%, so I assume they won’t ship full and all rechargeable battery self discharge over time, so with a slight discharge from that from storage, it should take a bit over an hour to reach 100% From full discharge, the included charger should take about 6 hours or so. Personally, I use a better multi battery charger that has percent of charge indicator.

Q: What is diameter in mm of the light body.
