I've purchased 2 Tec 20's and 2 Tec 40's over the last year or so, from different sources. One of each had the faceted reflector, and one of each had the smooth reflector. I agree that it seems to be an age issue - the retailers that seem to have the higher inventory turnover only have the faceted ones now.
Another difference I observed is on the battery contacts at the base of the body. The older? smooth reflector models have a mesh material covering the contact area. The newer? faceted models have just kind of a sheet metal blade in the bottom. I have trouble getting the newer ones to work with NiMH batteries (works if you screw the top on really tight if at all), where the older, mesh bottom units work just fine with any batteries I have tried. So while the faceted lense may be an improvement, the battery contacts may have gone the other direction.

I have a Tec 40 that I've been using for about 5 years (with old mesh contact). I've had problems with NiMHs in it, since over time the nipples (and even the bases) get pushed in. Some of my old NiMHs won't even work in that light anymore.
I have yet to have a problem with the newer flat contacts, but that could be because I've learned my lesson, and don't overtighten PT lights.
They DO need a little more springiness AFTER battery contact has been made.
