LOL! I just looked that up. I think their info on their website is missing a couple of digits. It says on High the light is 350 lumens for 1.5 hours. On low, it's 110 lumens. LOL!
I'd bet a dollar that is supposed to read 3500 lumens and 1100 lumens.
The video showing the spot beam looks pretty impressive. The specs say it will focus down to a 3 degree beam angle. I was skeptical until I watched the video. However, it also seems like it has no spill area at all. I'm not sure I would like that. Even at its wide, 18 degree, setting, it looks like there is no spill.
I think a 6 degree or so beam angle with a decent amount of spill is pretty ideal. A narrow beam with no spill at all is good for signaling, but it's not that great for actually seeing stuff.
