Nitecore T4K - 4000 Lm...keychain light?

https://flashlight.nitecore.com/product/t4k

Uh, ok. Like TM10K it will only be a few sec. at 4000 lumen of course. Might be useful though. Why don't they make these things configurable, so you could choose say a 1000 Lm turbo which would heat up much slower.

Seems to me that that is pushing the limit size wise for a keychain light.

Interesting, none the less.

I find that these types of flashlights are mostly to show what kind of power they can deliver in a smaller package. This will probably hold 4K lumen for like, 3-5 seconds which I dare say have no real use since the next mode is only at 200 lumen.
I guess it makes for a good "LOOK, HERE I AM!!!!" but since it probably drains the battery very heavily it's not really much of an emergency tool. But that is just my opinion! Hopefully down the timeline we'll have new types of LED or perhaps a new lightsource that can offer 4K lumen for a much longer time in a small package.

them lights wfich are nit round hurtbmy leg in my pocket

But of a push to call that a key chain light.
