    Has Nitecore done anything to speed up the PWM so that it does not have visible PWM on the lower levels?

    I am sensitive to PWM and the original Tube had a very low frequency.

    Don't really know as I don't have the V2. Not enough improvements to justify it.I have a V1 1/2(?) with lockout that works fine. Probably never notice the difference in output and I don't notice the PWM.

    The biggest upgrade they could do is make it more reliable.

    I've bought/gifted probably a dozen Tubes over the years and the longevity is wildly inconsistent; some lasted a few weeks, some a few years.

    It's a great design, and inexpensive but I feel like I'm just rolling the dice when I was buying them.

    I think they’re brilliant. But don’t underestimate their Lazarus-like properties. I’ve been sure a couple of mine have been dead (no power at all after a full charge) then a day or two later, work fine.

    Am I going to buy a V2? Only if I’m 100% one of the other ones have died and aren’t just resting!

    PWM? I must be having an Altzheimer moment (no, not mocking anyone... been happening a lot these days! :( )

    I've been a user and a fan of the Tube for years. When the TIP started getting some rave notices, I went ahead and upgraded to one. Now, don't get me wrong. Its good, and does give higher output. But in retrospect, for my needs, it hasn't been the best investment.

    I still have a Tube that I use to avoid stumbling around the house at night and I have one on my alternate key chain. Functionally for my needs not any clear benefits from my upgrade to the TIP. No defects in design or manufacture.

    L'chaim!

    It's probably a side effect of the Pulse Width Modulation (PWM) to which your flashlight is exposing you.

    Basically, most LED lights achieve lower levels by two means:

    Pulse Width Modulation: The LED flashes off and on at maximum output. For 25% output, the flashlight is only on 25% of the time. If the off-on sequence is fast enough, it is not detectable to the eye (though some people still claim to notice it). Some people are bothered by PWM. Personally, I get headaches from noticeable PWM.

    Constant Current: The voltage to the LED is reduced to reduce the output level. While this is more efficient and does not create a flicker like PWM, some people are bothered by the LED's tint shift, especially at sub-lumen levels.

    @indigo_wolf and @jag-engr: Thanks guys. I should have guessed it was the pulse or flicker sometimes but usually not noticeable.... (face plant)!

    Enablers! All of you!

    Another thing I have no use for, but now must have.

    Don't look at me - I hate the Nitecore Tube. I would advise you to buy some Sofirn C01S lights instead for about the same price.

    I guess I'm a counter-enabler...
