    GOOD HOBBY CHARGER VS. the PILA

    For me, the biggest benefit to having a hobby charger comes when you deal with many different types of Li-ion cells (Or different chemistries). Chargers like the Pila only charge at one rate, which may work well for 18650s, but too high for 10440s and too slow for 26500/26650. I personally use...

    Most powerful P60 incan dropin for 1x18650/2x16340 body

    Really hard to find something which will run on primaries since 2xCR123 under heavy load will only give you ~4.4V total. However, my personal 2xIMR16340 blaster is the WA1111 in FiveMega's G4 socket. (And actually, I prefer using the WA1185 in a 3x16340 setup) Honestly, neither of those setups...

    How many AAs or AAAs for runtimes as good as a single 18650?

    If you're JUST talking about equivalent energy, it's pretty easy. An average 18650 (3.7V, 2900mAh) holds 3.7*2.9 = 10.73Wh of energy. An average AA [eneloop] (1.2V, 2000mAh) holds 1.2*2 = 2.4Wh of energy. An average AAA [eneloop] (1.2V, 800mAh) holds 1.2*0.8 = 0.96Wh of energy. Thus, you'd...

    Lumen ratings...I see no clear answer.

    Even if you're rating a light OTF, there are many ways to do it. Do you state the OTF lumens at turn on, or after 30 seconds, or 3 minutes after it's turned on? (Light output always decreases over time) Or do you state the average lumens over the discharge of the battery? Or the minimum lumens...

    Why warm tint is more preferred in flashlight, scientific explanation

    I thought that I'd just add a reason why I don't think the Kruithof curve proves anything regarding warm tints being better - It's just a study of how a particular light source changes as the light intensity goes down: given a light source of given intensity and color temperature, if we are to...

    Why warm tint is more preferred in flashlight, scientific explanation

    I can't say that the curve proves that warm tints are preferred since it's based on opinion. (Also, is a "pleasing" tint necessarily better?) However, I can say that it does probably show that for lower lighting levels, a slightly lower color temperature than one's preferred tint may be ideal...

    Neutral the preferred light?

    I'm not sure about that, all I am trying to argue here is that you can't put a fixed label on a measurement which people perceive differently. A good example to add on to the others already listed - temperature. A "neutral" temperature could be defined as feeling neither hot nor cold. For me...

    Neutral the preferred light?

    However, when I take what I personally consider to be neutral - i.e. a 5500K source, someone else is going to say it's not neutral, but actually warm. Another person will say it's not neutral, it's actually cool. IF neutral was by definition neutral and didn't have tint or hue, wouldn't it have...

    Neutral the preferred light?

    This isn't true. (However, in the case of LEDs, it's almost always true. Perhaps this is what you meant?) If you consider daylight [sunlight], which is ~5500-6500K "neutral/cool" white - it gives very good color rendition because of its smooth and continuous spectrum. You could have a neutral...

    Liteflux LF2XT Discussion Thread (Part 5)

    In my case, FUI is what I use, and the tailcap was on as tight as possible. I myself discovered the loosened tailcap issue 2 days after I got mine - and my issue is definitely not related to that. However, it is indeed very good advice when troubleshooting - always make sure all the parts are on...
