I am thinking about adding a light to my personal defense list. This would be something that I would slip into a pair of shorts or a coat pocket. As with my knife and gun, the light would have to be comfortable and compact for me to carry it. In terms of my expectations for using it, I want something that could blind someone for even just a second so I could either get away or go for my gun. The SF E1E looks very attractive. It is a full 1.2" shorter than the E2E. However, the E2E produces 4X the amount of lumens than the E1E. Now, I know what 60 lumens looks like - I have a G2 Nitrolon and a Z2. My question is, how bright is 15 lumens? Will it have the desired effect? Is there an alternate option on the market that is as compact as the E1E and maybe a better bargain. I don't mind paying for qaulity, and I sure do like SF's, but i don't want to waste bucks either.
