Lost all will power when the Mocha's went on sale, got two. Love this little light, neat form factor. Beam is what you would expect from an orange peel reflector smaller than a Cheerio, has a hotspot, but it is HUGE - very useful for what I will use this sort of light for. High is more of a burst feature in my opinion, as evidenced by the 22 minute run time and the heat generated in the narrow head, but it gives the wide beam a lot of throw via brute force. It actually tailstands on the button, but you need a good surface and have to balance it carefully. From the pictures I thought it might be a bit big to carry in a shirt pocket like a pen, but it is definitely not, size and weight are great for this.
Did not care for the level of green tint in one of my two samples, so I added a tiny Pale Gold Lee filter to it, and it is a pretty neutral tint now, very nice. Just a tip, for a while I thought for sure my switch was wonky, mode skipping, changing modes if I just wiggled the button or tapped on the light, but would not change from high by accident once there. Make sure the main joint in the tube is good and tight. That got just a bit loose and wreaked havoc. The upside of that is that if you give it a quarter turn loose, you have full lockout, as mentioned. I like the approach Lynx Arc used for adding thread retention with teflon tape if you are going to carry it this way. I have used that on a few of my twisty lights that were too loose also. In my shirt pocket, I don't see any threat of accidental activation.
Thanks for the great deal, FourSevens! Now I have these to compliment my other 20+ FourSevens lights
