Congrats on your Lumen measuring capability, great to hear it is working well.
> As soon as I re-set the ceiling to my preferred 120, the memory reverts back to level 4, or 80 lumens.
confirmed, changing ceiling and using stepped modes, does not retain exact memorised output.. but if you switch to smooth ramp, the memorised output is still correct
Try using smooth ramp instead of stepped. I just did a test and the memorised level was retained after a ceiling change.
my guess would be that stepped modes get recalculated based on Floor to Ceiling range.. (and number of steps)
fwiw, I found that if I use 9 stepped modes (with no manual memory), with a floor of 2 and a ceiling of 120, that level 7 gives the top of the 7135, 120 lumens (my test light has the cool white LED), and level 7 can be memorised (or not).
I also find that using the 7th of 9 steps, gives top of 7135 (NoPWM on the Opple flicker test), on my modified TS10 w sw45k.. the output for those LEDs is 90 lumens.. but the 7th of 9 steps consistently gives top of 7135 (w floor of 2 and ceiling at 120... technically level 121 of 151. I use 3x 1H to drop 30 points)
thanks for sharing an in depth exploration of Anduril UI, I appreciate the way your mind works ;-)
