The idea they have adopted for their E series lights, a TIR lens, now makes me think if Fenix gained some way in using this type of optics. I have an E05, an E11 and an E15 in the mail now. I guess they can give an idea of what Fenix may have achieved in LD 30 and 50. Throwy but ugly beams I guess. Maybe the optics contribute the OTF lumens?
I have been playing with some TIR lenses for a week. A mismatched optic makes a total mess, and the beam out of a reflector is almost perfect. You're right. My TK lights also have greenish tints. I would definitely prefer a more natural white.
