    Ultra High CRI AAA option, JetU E21a, and JetU Solis, post your beamshots

    a) Please elaborate on how you would cause the camera to bias the results, because I am simply curious. b) Explain please what you think a raw file does with the stored white balance number, such that it matters if it shows the same or different. I do not think I can have understood correctly...

    CLOSED 2018 Yuji 3200K high cri 5mm LED group buy

    My solitaire is running at about 50mA continuously I think. (hard to get an accurate measurement). I think they're fine at that level indefinitely. But I'm not sure they'd be useful if they weren't bipin.

    Serious Q: 16340 flashlights: diff betw $5 cree and $40 Fenix

    Do you have any other flashlights at all? What's the one you refer to that uses a 26650? Because in general, as soon as you try a better one, you notice the difference. Still, okay, let's think this through. A 16340 contains about 2.6 watt-hours of energy. You get nearly 10 hours of light from...

    UltraFire 18650 5000mAh battery?!

    Fsck no, those cells are the worst possible idea - trust me, they will find a way to make it not worth the couple bucks you save. They won't be as much capacity as a legitimately rated lower tier cell, they'll barely handle any power at all, they could die randomly, might even randomly go off...

    Re: 2018 Yuji 5mm LED group buy OPEN Update: Finally bought a lifepo4 10440, put it in the maglite solitaire, and after removing the reflector and a little of the bipin plastic parts, I have myself a 1x10440 direct drive yuji LED! https://imgur.com/a/lhViMfK The resistance of the host seems...

    New 18650 Battery at HDS

    Datasheet Eh? Is this the one that also gives a Typical capacity of 3450mAh and Minimum of 3350mAh when tested at 25* C and in fact the Rated capacity is only 3300mAh at the slightly colder 20*C? Which, in fact, is an important thing to consider, though not as important as starting and ending...

    Maglite Incan Solitaire

    Got it about 10-15 years ago; used to read by it at night, it's not amazing but the candle mode (ie remove the front fully) was neat, I suppose. And when I'm dark adapted, it's still too bright at short enough distance, but it's somewhat easier to muffle and less glaring. It's not amazing, but...

    Maglite Incan Solitaire

    I actually have a solitaire, but mine is definitely a warm white color - so there's a different version out there, in addition to the new led ones?

    Is it really too bright for you?

    red light

    I do think red light has its place, in that from looking at a relative sensitivity chart, I saw that of all wavelengths, it was a shade of red where the sensitivity of the rods when dark adapted versus that of the best suited cone were closest; the rods are much more sensitive at the blue-green...

    Single Battery Putsch?

    Counterexample: 2xaaa/aa, especially in direct drive for simplicity. Very useful small lights, and eneloop nimh aaa's are very stable and last many recharge cycles. Also, I will not use any variant of cr123 willingly, but that's perhaps just me. I definitely don't want primaries except as a...

    Triples/quads are on their way out...

    Multiple emitter flashlights on their way out? As if. The emisar d4 has been flying off the shelves so to speak, and there's plenty of people interested in the fw3a triple. When there are small emitters capable of more throw than is always needed, there will always be the option to put several...

    CanCooler 4000

    Re: Can Cooler 4000 Yeah, I've seen plenty of times before that they didn't have any sense about some things; once they did a huge cooling loop but didn't do very good plumbing and didn't realize they had to do something to keep stuff from growing in the coolant they used. And they have been...
