Thanks for that. The T1 does look similar... cant chance it though as the glass will be coming from US to UK. May fire off a mail to Fenix if no-one knows for sure.
I'm interested how you managed to open the head, because it is glued on the most Fenix flashlights. I have TK15 with blurred glass (factory failure), but it is impossible to unscrew the head. Dam'n blue Locktite is unbreakable!
For anyone thats interested, Fenix say 28.6mm x 2mm. I didnt even think about opening the head. I think ill discretely see if i can open the head on my friends TK11 next time im there before i order a new lens.
