Given the problems that cropped up regarding use of the Ti bezels with the 27LT-S, I read this thread carefully before ordering. I figured that any possible issues with that light would surely be noted, but the info given was that the bezel should work with all 27LT lights.
Unfortunately, that is not the case--it doesn't tighten down against the glass of the 27LT-S, as I discovered when my bezel was delivered yesterday and I tried it last night--which is the same problem as the Ti model. And it makes no sense that this would only happen on some 27LT-S lights--it's not as if Don is building these lights out of parts with varying specs. The specs for each part--head, reflector, O-ring, glass--are the specs, and the bezel either fits properly or it doesn't. It doesn't, period. It's not even close. Tightened to the max, the window glass still rattles.
Wondering WTF? and figuring that I couldn't be the only one having a problem, I logged onto this thread to see that a new warning has been posted about these issues, and that the 27LT-S requires a thicker O-ring or window for use with this bezel. Why wasn't this posted from the beginning, given past experience with the Ti model? I would bet that most buyers of this SS bezel are getting it for their recently purchased 27LT-S lights.
A warning to 27LT-S owners using this bezel without a thicker O-ring or window--do not submerse your light! Your window may not rattle like mine, but you surely do not have a watertight seal.
Well, it's off to B/S/T to sell this bezel.
