    On the left is gunga's 90+CRI N219c 3000k, it is absolutely gorgeous, imo. The middle is 4500k N219b 90+CRI, right is 6000k XP-G2 70CRI


    Neat! $77 is a little pricy though. I know. I'm a pita. My Vinh model didn't cost much more than that. I will think about it but I expected it to be like $40

    What are the triples?

    What is the light on the left?

    What the tint look like on the Neutral v11r?

    The stock Neutral is LOW CRI. I agree that is not the best deal.

    You Can get Cool White LOW CRI V11R for <$40 if you look.

    However, for a tint and CRI snob, the best deal is to get a High CRI Nichia mod, you choice of Warm or Neutral, by sending a PM to gunga.
    ...
    The ripples are Mecarmy PT18 with 4500k N219b swaps, modes are 5-50-200-1000 on 18650, and stock PT16 XP-G2 6000k modes 10-100-300-1000 on 18350 IMR.


    The Mecarmy pictured are NoPWM lights. The V11R is also a NoPWM light, here is a short test of that with the Warm High CRI Nichia.

    How Our Eyes Work
    Our eyes can be quite insensitive to some types of brightness changes.

    Below is an excellent explanation from HDS, how it works, that people do not notice PWM, fluctuations in brightness, constant current ripple, regulated current with a feedback loop, circuit noise, and other circuitry that do not provide fully regulated output. A light meter, and sometimes other instruments such as oscilloscopes and cameras are Required to “notice” some changes in brightness, such as really fast ones, or gradual ones, or small lumen amounts.

    Most people would Not notice the fluctuations in the V11R in use. Even selfbuilt, who Knows its there, does not care.

    quote from HDS Systems in italics:
    Your eyes have a non-linear (logarithmic) response to light, much like a camera. In order to notice a significant increase in brightness, you must double the amount of light. In photography, this doubling is referred to as an f-stop. For our purposes, the f-stop is a convenient unit of measure and we will use it when referencing relative brightness. To put this in perspective, if you suddenly change the brightness by 20%, you will notice just a slight change in brightness. In fact, if the change takes place over a couple of seconds, you may not even notice.

    In my case, Im interested in Light Meter readings, because it informs me about potential battery life, among other things. I don’t want a light that increases its brightness beyond where I set the dial, because that drains my battery faster than I want it to.

    This is not to say the V11R is not a fascinating light, for many reasons, and Im not in any way criticizing or judging anyone that enjoys theirs. I do believe that ALL V11R, and ALL magnetic ring lights would probably exhibit similar unregulated flux as the V11R. This is not a single defective light. The Light Meter response I am discussing IS universal to the design. I invite anyone that would speculate otherwise, to put a Light Meter in play before repeating a phrase like "I don't notice in actual use" :-)

    I posted in this thread to discuss Light Meter readings of the V11R, because I discovered a fascinating flux in brightness.
    “I don’t notice it in actual use” misses my point, that the V11R does not have regulated output, that the brightness continues to drift in the direction of the last dial turn, and that even rotating the light in the Earth Magnetic field, will produce similar results as rotating the magnetic ring around the light.

    On a light meter, the V11R changes brightness, at times by more than 30%. I think its worthy of a science class show and tell, about how the earths magnetic field effect can be seen with an LED!:-)

    fwiw, the Earth Magnetic field also pulses, within a narrow range, it has PWM, fluctuations, not fully regulated, hence the beauty of the V11R as a natural candle with fully entrained synchronization.

    < begin marketing hype> Imagine a Warm nightstand candle that glows with the Rhythms of the Earth. Imagine the movement of your lover illuminated by the warm rhythmic glow. ;l-) < end hype>

    Question on the V11R: does it behave differently with RCR compared with CR123a when getting low on juice? I thought generally that RCRs "just go out" with little to no warning whereas primaries go out gradually, which itself is a type of warning. So first, is that true in general, and second is it true specifically for the V11R?

    No...output is about the same but a CR-123A has roughly three times the capacity at approximately the same voltage.

    Now, a 16340 li-ion at 4.2v will almost double the V11R’s output.
