    Olight Smini

    That's why I said "if I understand it correctly" - none of the UI descriptions are ever as detailed as I'd like. :) Turns out my new S1 also has the timer in Moonlight, so they did think of the most probable use case after all. :)

    Olight Smini

    Yep, that's what immediately jumped out at me: good idea locking that thing in place so we can form some tactile memory and find the button quickly and reliably every time we put our hands on the flashlight, but bad bad idea on the orientation. The button has no business facing the clip and...

    What colour temperature is subjectively closest to "pure white"?

    I don't know about that. There's an undeniable presence of violet frequencies in the early morning twilight that's inconsistent with low color temperatures. http://www.superhqwallpapers.com/2560x1600-high-quality-wallpapers/twilight-morning-2560x1600/

    What colour temperature is subjectively closest to "pure white"?

    I would submit rather that the reds are well represented because 20 kK is well into the violet section of the spectrum, where it's nearing red again.

    Olight 18650 3400mAh - what do you think?

    You're not kidding - I just got an Olight "18650" 2600mAh battery and found that at 68mm it's just long enough to prevent the Olight S20's fully screwed-on tailcap to close the flashlight's circuit => Olight's own 18650-compatible flashlights won't even work with Olight's "18650" batteries...

    Test/Review of Fenix 18650 ARB-L2 2600mAh (Black)

    Haha, thanks for that! Your reply made me go back to try one last time and as I did that it occurred to me to try to connect the charger to the mains and just measure the voltage between its terminals with no battery: 0 V. :) Turns out one of its terminals was a piece of metal soldered directly...

    Test/Review of Fenix 18650 ARB-L2 2600mAh (Black)

    I think I just killed one of these with my Olight S20-L2. I had been using it on its first charge for so long I had forgotten than the S20's button LED was supposed to turn red to signal that the battery was close to empty, so I kept using it even after seeing the red light. What finally drew my...

    Olight S20-L2 (S20 2013, XM-L2, 1x18650 2xCR123A/RCR) Review: RUNTIMES, BEAMSHOTS+

    It will fit in most pockets, but I wouldn't consider it comfortable to carry in my pants' front pockets for example, as it's just a bit too heavy and it would dangle around in a way I'm sure I wouldn't like, plus I'd probably feel it when I sat down too. I carry it in my cargo pocket at the side...

    Olight S20-L2 (S20 2013, XM-L2, 1x18650 2xCR123A/RCR) Review: RUNTIMES, BEAMSHOTS+

    There seems to be some confusion in your description above (see red text vs. green text) - I just got the S20-L2 today and found that unlocking it requires the same type of press as going to Moonlight mode: a 1-second sustained press. Pressing the button for 2 seconds from lockout does...

    Police Study of tactical use of Strobe

    Actually, I never considered using strobe against a dog, I always just pictured myself blinding it with a continuous high-beam while backing away. Humans I would have to strobe because they can put their hands in front of their faces and still try to advance. :)

    Police Study of tactical use of Strobe

    It's funny you should ask that, because that was exactly my primary intended use when I got my first "tacti-cool" flashlight. I never got to test it because I later convinced myself to give an ultrasound device a try, so when push came to shove I preferred to pull out that one (while also having...

    Police Study of tactical use of Strobe

    Got me again. I just can't get any good days for science, apparently. :P

    Police Study of tactical use of Strobe

    Yep, apparently I did get confused - those two specs I quoted were actually quite different: 9000 lux @ 1 m => 31.36 lm into that beam that makes a hotspot with a 0.2 m diameter @ 3 m, so 9 kcd in this case 1000 lux @ 3 m => 62.7 lm into the same beam, so ~18 kcd in this case. Now if we put...

    Police Study of tactical use of Strobe

    OK, so both these specs suggest you want to throw at least ~63 lm into that very tight hotspot that's 0.2 m in diameter at 3 m distance. Unless my Wikipedia-based math is out of whack, this translates to an intensity minimum of 18 kcd for that hotspot, which is pretty close to what Max was...

    *new* Fenix PD22

    Meh. Then I already know I don't like it. I prefer a constant-frequency strobe because I found I could also occasionally use it as a dancefloor light at house parties :D (which I actually did with my PD30 three times in the three years I had it).
