I've got a Fenix, too. Great light. There's plenty of good tactical lights out there. I'da been happy with many, I'm sure, but this one's as nice as I've ever owned.
Funny, I was just going to tell you about my recent purchace of a Fenix and I read the entire thread to see Asyum's link.
Yeak, Fenix TK09 will light up the crack of dawn. I bought this at REA in Chuula Vista on a visit to buy something else... I like good flashlights.
This one I can recommend.
Best,
Rob
