Turned all lights off in house and had the GF shine it towards me and damn is it bright!! The strobe is enough to disorient you. I shined her direction and I was shocked how much light it gives off.
I took it outside and shined up a pine trees and you're right, you can see detail of the whole tree. The beam is very wide, not a straight laser type beam. Does not appear to be adjustable. I will say it's far more than I needed. I'll never take this off my shotgun to use for anything else since I rarely use a flashlight in my daily life. I could have gotten away with that Nebo I returned.
I grabbed two CR123a batts for walmart for $10. The 18650 I read is usually only found online. I will hunt tomorrow.
Thanks for the suggestion... Great light.
