The postman just dropped off my L0-Ti.
I won't pretend to be able to add any insight to the reviews already presented on the CPF. I just want to say that I own a bunch of torches from SureFire, Inova, Fenix and others, and this newest little gem can stand shoulder to shoulder with any of them.
My current keychain light is a Fenix E1, but this L0-Ti has a cleaner, whiter, more powerful and much more useful beam than the E1. It is going on my keychain right now, and I'm just thrilled to own one. I hope for the rest of the world that Fenix quickly produces the same light in anodized Al (and maybe a Cree) so that the same qualities become available for more people, without the more exotic (and expensive) metal Titanium.
