Could you image if every member of CPF got together at like a gun show venue and every one brought all their flash lights for members to look at and compare.
The worlds first ever flashaholics flash light fair ????
Not to rain on the parade, but everyone bringing ALL their lights would kind of be an invitation to redundancy, especially in the realm of common, everybody-and-their-dog-has-one kind of lights. I intend no disrespect for widely available lights; many are really really well made and useful (for example, the Lumintop Tool v.2.0).
That said, there are some really special lights that I think it would be worth drooling over: we have no shortage of custom builders whose work and craftsmanship inspire envy among us lesser mortals. There is also a case to be made for a showcase of lights that are no longer in production, or that feature some less common engineering (piston drive mechanisms for example, or Fraz Labs
lights that are always labeled as being out-of-stock).
I can also see some "fun" stuff, for example a kind of shoot-out where really extreme throwers are displayed in action to dazzle the assembled multitudes, or perhaps a demonstration of just how far various good quality outdoor-oriented lights can be seen by SAR personnel (I'd personally love to know how readily some of my lights can bee seen at a distance, in case I need to signal a rescuer some day).
