thanks for the visual confirmation
fwiw, turning the rotary dial from min to medium and letting go, produces the same result as rotating the whole light. After I stop turning the rotary dial, the brightness continues to climb.
Same going down, if I turn the rotary from max to medium and let go, in actual use, it again does the same thing as rotating the light in the video. After letting go of the adjuster ring, the lumens are not stable, they continue to drop by themselves.
The videos I posted were just an example of how unstable the brightness is, from any change in brightness, either turning the magnetic ring, or turning the whole light.
Im glad you never noticed visually, selfbuilt and I noticed on a light meter, which makes the instability really obvious. Its a shame, cause I guess I had hoped the ring would be accurate, and stable. Instead its inconsistent and changes, even after stopping movement of the adjuster ring.
As far as moving the light itself, I often reposition my light to shine from different angles. On a V11R, this changes the brightness in ways that are obvious with a meter, and not so obvious to you by eye.
all good, interesting learning. Thanks for the feedback.
