It is "AA size" it isn't that impossible for an IMR 14500 to do that.

True. 600 lumens is easy with a 14500. Still would like a link so we can see it.

It's nice but for that price I can't imagine not opting for a Xeno or an SE-1.

I haven’t got the link to the item, but here is a written review about this light, with a Link to Kaidomain .
They seem to provide legit lumen ratings!

for the link scaru, I was late coming back to the thread, (been out all day)

“True. 600 lumens is easy with a 14500.”

Well I’ve learned something today, lol.

For 5 minutes.

eo3 can do about 450 on a regular 14500. and IIRC the eagletac d25’s did like 900 with a 14500? something ridiculous like that?

No more 'bull' than most of the ads for Chinese flashlights.

Ebay claims are usually the most outrageous.
