I made a PL47 anduril ramp configuration estimated [stepped] lumen table so i could see theoretical lumen values of ramp ceiling minus n. So eventually 2 clicks will be my normal operating level once i determine highest level it maintains, and the table will give me a basis for estimating what lumen level i am running at. assuming my table is even slightly working
I assumed i start at 150 and i did it in increments of 10. The nichia with a blf user estimated max level of 1800lm (texastoast/skv89). The xpl 5000k blf est max level>4000lm +/- 250 (newlumen/skv89) and the sst 4000k est blf max ~2500lm (komeko)
Obviously, reports are still coming in for lumen estimates so that piece is REALLY ROUGH and turbo seems to be a function of which cell, and only at turn-on, etc. But does my scribble table work? Or is there some wierd curve or slope thing that would render my table completely off, in other words does regulation and magical electronicky stuff inside the light, make a table like this kind of favoring like say a bell curve or something. I think what i show is a linear breakdown of ramp ceiling (or floor if you go the other way). But i dont know the hardcore aspects of how it really works, so i dont know if it holds up. But i wanted to have some foggy sense of what my ceiling lumen level would be once i discover what level seems to hold without dimming. I understand there are many variables like lite temperature, battery level, room temperature and these sorts of things that are not accounted for in this table—but as a rough estimator could this sort of work?
[Edit: i guess my working assumption is that the ramp function is a consistent linear progression like the slope of a pyramid, each step spaced equally from one to the next. As opposed to say the slope of an inground pool, where it (output)is weighted differently at different points on the slope….i guess, and this is way above my paygrade so i cant quite articulate it but i can visualize it, in mathspeak logorithmic/ exponential/ or linearithmic slopes, or some kind of curvey hilly thing vs a straight incliney thing].
So.: to explain the table, for instance, take nichia @~1800 max lumen. 1800=150 on ramp config. Minus 10 presses (140) gives me a theoretical lumen value of 1680. And so on and so forth. Math is 140×1800÷150=1680…130×1800÷150=1560. [Linear] vs 140×1800÷150=1680…(130+/-n)×1800÷150=x. Or ((130×1800)+/-n)÷150=x[curvey]. or something like that, to indicate that each step is not equally spaced from adjacent steps.
[Edit2: and frankly it feels like there are 2 independent pieces to this equation. Spacing as in distance in the ramp one step to the next and secondly, output as a distinct variable independent to the spacing because of driver and such. It would be nice if my simple formula works but it feels more complicated than that.]
I should have paid more attention in math class.
Does this even come close to holding up or am i completely off?
And i guess the follow up if it seems sound could i use the same simple math to figure out levels within a stepped configuration. So floor equals 10 ceiling equals 100 with 3 steps. So for the nichia i arrive at step1 ~120lumen s2 ~660lm s3 ~1200lm.
Any thoughts appreciated.
