thank you for sharing your test results, very helpful
which LED?
which lumen level is high mode (battery type changes this)? but in either case that is less than 5% change.
thanks for the warmup change info, thats 27, but according to HDS we dont “see” a change of less than 40
at 24 lumens the change is just 8%, Im fine with that
I dont understand your use of 360 and 720 degrees, to me that means one full turn, and two full turns… is that what you meant?
the change I see is by rotating the light 180 degrees, iow, half way around… first I locate which way it wants to face to get the highest level. I believe these effects are caused by the earth magnetic field interacting with the magnetic ring.
and I believe that some LEDs with lower forward voltage might be the cause of more magnetic sensitivity… not sure
regulation is not always precise. Even HDS fluctuates by 2% on a given setting, it will climb then drop, then climb again, within that range. It is not visible to the naked eye.
what bothers me more with a magnetic light is that the lumen drift continues after I stop turning the dial. And you might notice that if the dial is turned upward, the drift continues upward. And when the dial is turned to a lower level, and released, the drift continues downward. Kind of fun, but not if I can see the change and have to keep repositioning the dial over and over. That was the problem with my 3000k 219c modded V11r, the drift would continue after I stopped touching the dial, and it was a very large amount of drift, that I could see.
With my N219b 4500k 9080 in my RRT-01 the drift is small enough that I cant see it… less than 10% at the 100 lumen range. The drift is a larger percentage at lower levels, approaching 30%, but also a smaller number of lumens.
Very few “regulated” lights, actually produce constant lumen levels, but usually the fluctuation is not visible to the naked eye.
