Lee1959 makes a very good point. We get caught up in technology ... who makes the latest and greatest ... and forget what we really need to get by. Finding even the cr@ppiest, plastic, 2D, slide-switch, Ray-O-Vac incan with weak batteries would seem like a miracle to average people trapped in a pitch-black building.
CPFers/Flashaholics would spend the first 15 minutes pointing out how shoddy the construction is, disassembling the light trying to polish the contacts and lastly critiquing the 'ringy' beam.
But a 2AA Minimag incan with decent batteries would be better than the Ray-o-Vac imagined above
by far. So, if you were able to get a pallet of them for pennies a piece, I'd jump at the opportunity. You could put two or three in every kit.
There's a saying: Quantity has a quality all its own.
