I received my E2DL and it's a fine piece of kit. Well, curiosity got the best of me so i decided to test the blinding effects of the flashlight. I held it at arms length from my face, I looked at it, then turned it on. Needless to say, i'm still seeing stars. As soon as i turned it on, i had to look away. And for a good 10 minutes or so even after this moronic experiment, i was still seeing a "hotspot" right in the middle of my vision. Am i an idiot or what, but I can sure see how this light could be useful when flashed into the eyes of an attacke or some bad guy.
