magnetic control ring lights have difficulty maintaining brightness regulation due to the Earth's magnetic force lines.
I had a V11r modded to 3000k N219c and after that the light was unuseable, for me, because it would vary by more than 50% brightness, depending if I faced north or south
Nobody else confirmed my data in a V11r. Its hard to find someone with a light meter that owns a modded V11r.
So I was reluctant to change the LED on my RRT-01, as I feared a similarly large change in brightness fluctuation.
The one person I found to do the actual tests on their RRT-01 modded to 5000k N219c triple, did not see the large percentage variation I got in the V11r. They were reporting a change of less than 20%. Bear in mind that unless a change is more than 50%, it is not noticeable to the naked eye, although its plenty obvious on a light meter.
I decided to gamble
I took measurements of my stock RRT-01 and it varied by less than 10%, near the 100 lumen range, not a visible change, with its stock LED.
Had it modded to a single N219b 4500k 9080, and hurrah! the change in brightness was below 10% still!.
I just tested it again, here is a video
and a snapshot of the smallest and largest value, an increase of just 6.5% in this test, at this lumen level.
By contrast, my "fully regulated" and stock HDS Rotary only varies by 2% on maximum, and it does that just sitting still, it makes no difference which way it is oriented.
My Novatac Spa only varies by 3% on maximum, again even just sitting still, orientation has no effect. And btw this Novatac has the same N219b as the RRT-01.
the change ln the RRT-01, from different orientation is much larger at lower levels, it is 31% near 3 lumens, for example I see 2.9 to 3.8 depending how I position the light, but that is still not visible.
The N219b into RRT-01 operation was a success and I have fallen in love with the Magnetic Rotary UI.
My RRT-01 w 219b (low below 0.1, high of 380 lumens) has become my main EDC, displacing an
HDS Rotary w Cool White LED (low of 0.08, high of 200 lumens), and a
Novatac w N219b 4500k 9080 (low of 0.1, high of 270 lumens).
Now I would like to buy a Niteye Eye 10 TiC, please PM me if any of you have one available.
I want a strobe option that is lacking in my RRT-01
