Arthur Clark postulated, "Any sufficiently advanced technology is indistinguishable from magic".
You know how it goes- show up at an Indian encampment in 1712 with a Zippo & you'd pretty much be a god (or at least a guy to be really good friends with).
I've been fortunate enough to witness a crap-load of technological advances in my lifetime (can you say "internet"?), but some advances, being enhancements of known technology, just floor me.
See the magic:
This is a Streamlight Microstream, & it's pretty cool. But this particular model is not the subject here, it's the WOW factor that flashlights have achieved.
When I was a young-un, a flashlight was a two "D" incandescent contraption that might, on a good day, get about 20 minutes of usable light before devolving into a yellow glow emitter that was not much good except for finding the flashlight if you had left it on. And that only lasted another 20 minutes & you were then, officially, SOL.
Now, look at that picture- that light is 3.5" long, 9/16" in diameter, & weighs just over 1 ounce, with the AAA battery. It puts out 28 lumens (I'm told), but I can light up the barn over 100' away. And, it will do so for over 2 hours on one silly little AAA.
I recently bought a Fenix "tactical" light that puts out 180 lumens on 2 AA batteries. Word is it will do that for 2 hours as well (longer on lower settings).
Stunning useable technology...all within my lifetime.
Now I gotta go research upgrades for the LED headlamps, themselves magic in their own right.
My name is DT, & I'm a flashaholic...
