Does the JetBeam BC10 overheat?

Does the BC10 overheat if you run it on high until the battery dies?

270 lumens seems like a lot from such small light.
My Fenix LD20 R5 heats up quite fast on turbo and it's only 180ish lumens. That makes me wonder if the BC10 overheats if I leave it on high constantly.

Define: overheat.
A single cr123 won't have the runtime of 2xAA, so exposure to heat will be less. 40 minutes here http://light-reviews.com/jetbeam_bc10/ 45 minutes here http://www.candlepowerforums.com/vb...-amp-BA20-Reviews-RUNTIMES-BEAMSHOTS-and-more!
A [quality] cr123 should have a PTC, so if it gets REALLY hot, the battery will throttle down.

Are you really expecting to get 50,000 hours of LED service life?

By overheating meant if it will get so hot that the LED gets damaged and dim quicker.

I have a jetbeam bc10, doesn't seem to get hot. I need to find a cheap flashlight holster for it because when I use it for work, I'm always activating the momentary on. Any recommendations? *cheap*...I was actually thinking about the led life the other day, and did a little research --doesn't seem like it would be easy to replace the emitter in these lights.

Jetbeam usually designs their flashlights to run on max output. I have their Jetbeam III M XML which it only puts out 450 lumens, but they could have pushed it harder which would have been more impressive.

Does not heat, even if the construction is pretty light if you compare it to most of the other Jetbeam models.

No, if you run it until it is flat on high, sure it will be warm but thats normal.This is an extremely powerful xp-g single cr123 with 260 otf lumens as tested by selfbuilt who also commented it was one of the most powerful xp-gs he has tested to date. Ive had mine for a couple of months now, still amazes me, a true pocket rocket.

Aren't there several over 300 lumens with 1 rcr123?

The jetbeam bc10 was tested by selfbuilt on rcr123s it had 460 otf lumens. But this was not recommended due to high discharge rate and low run times.I just use the std cr123 as thats plenty.

I have tried mine with Ultrafire protected 16340, it only lasts for about 20-25 minutes, and it gets very hot 😱

WOW, 460 otf??? If it's true that IMRs can handle a high discharge rate, I'm looking forward to getting this light w/ those batts to give it a go.
