KT,
Your insightful and entertaining post had meaning for me beyond flashlights and my diminishing obsession with them. The birth and eventual death of an interest, a passion, an involvement. That's the primary meaning your post had for me, and that's why I felt a brief sadness when I read it.
It reminded me to take a clear, honest look at myself in several areas, including flashlight purchases. I too am gradually narrowing down my collection by asking myself what I actually need lights for and which ones best fulfill those needs.
I agree that incremental evolution is the rule, rather than revolutionary breakthroughs which can occur only when we breech currant limitations of battery capacity and lamp efficiency, or somehow work within them in an innovative way.
I carry lights for utility and emergency so there must be a combination of long burning (like your Inova) and very bright (your Taclite). Runtime doesn't seem to be much of a priority in CPF, but it is very important to me. Since there is no small really bright light with extended runtime, the only way around that is to carry at least two lights, one of them being LED, though a 4AA like the UK Q40, or 4AA might be a compromise with a 5hr+ runtime on lithiums.
For me, the most impressive recently introduced light is the Tigerlight. Even without the OC option, the FBOP is unique. It is the only commercially produced light that combines a very bright light with a one hour steady output in a relatively small, relatively light standard flashligfht configuration. Randy Teig has worked with available technology and created something that did not exist before. On top of that, the light is highly functional in a professional environment.
KT's was the only voice I heard asking Surefire to produce such a light. They didn't and now Tigerlight is here. Surefire's A2 shows considerable promise, but is not yet available.
IMO, true innovation, especially functionally superior innovation will continue to be intriguing and perhaps exciting even to the jaded Flashaholic.
(EDIT) Perhaps I should have mentioned my great respect for innovators like Peter Gransee, and even Surefire for their recent foray into the world of LEDS, not to mention our intrepid modders who are trying to push that all too stubborn envelope.
I certainly didn't intend to neglect them, but they can only work with available materials, and until lamp efficiency increases significantly they are limited, no matter how great their creative brilliance may be.
