Grouping of flashlights by purpose (\"binning\")
In coming back here to try and focus my useful flashlights, I've also updated my Web pages to discuss recommended and suggested lights.
I'm starting to think that we often spend lots of times comparing lights, but it's important to compare for a specific task or use.
Brightnorm's recent Vertical Throw Test was a good example. Kenshiro's great work a year ago on spotlights was another.
I've discovered about for "bins" of flashlights that I use:
(1) tiny, long-run, not much light: Arc AAA LE
(2) EDC, more light, less run: Arc sLS (wife) SF E2e/KL1 & L4 (me)
(3) Utility around the house: SL 4AA, SL 3C, Lambda Illuminator
(4) Long throw: 9P+SRTH (me), UKE SL6 (two around the house), SL TL-3 (my EDC, car)
(5) Longer throw, more light: Vector 137 (Banana)
(6) Beyond that, what? A Maxi Beam? and then a WWII aircraft searchlight?
What happens is things quickly escalate as the candela output needs to go up by the square of the distance covered. For example, to get 1fc at 100 feet, you need 10,000 cd. To get the same illumination at 300 feet, you need 90,000 cd. This jumps you from the long-end of the TL-3 (or short end of SRTH) to the Banana.
So how do you bin flashlights? I find I use them more when I select ones that are far apart. I get confused when they all cluster together.
Cheers,
Richard
