My compliments. Your review of the EOS is well very done, and I must say that, having used the EOS extensively for the past couple of months, I agree with virtually all of your conclusions.
I would not, however, be quite inclined to give it a "5-star" rating as did Doug Pribis over at flashlightreviews.com.
The failure of PT to build-in some kind of lens diffusion mechanism is a non-trivial issue in my opinion, especially since we see
how easily the problem could have been solved. I'm referring to the new Tikka XP which was unveiled recently at the Outdoor Retail Show that includes a very slick sliding diffusion lens. As a work-around, I've used 2 or 3 kinds of tape over the lens to make it more of a "camp worthy" flood light, but even fairly clear tape cuts light output noticeably. One poster on the candlepower forum (see link below) has, in fact, retrofitted his EOS with an add-on lens (the Surefire E-size Beamshaper) to help disperse the light for close-up use.
I'm sure PT recognizes the issue and I'd bet there's a solution in the works. If they get this problem fixed, the EOS will, IMHO, deserve a 5-star rating as a do-it-all headlamp.
