Re: Insight M3X, two CR123s, 125 lumens for one ho
Welcome to CPF io333. There are others on this forum that know a lot more than me regarding lumens and runtime, but from what I have learned, most companies exagerate their output and runtime claims.
Streamlight might be correct however, they claim peak output at 125 lumens. It might put out that much on new batteries for a couple of minutes, and it might run for at least an hour. But it probably won't put out 125 lumens for an hour.
