:welcome:Absolutely love these, got one on every car key my extended family own, way better than the cheap tat they used to have and should last.
Thanks subwoofer. Are you sure it's PWM at that frequency (as opposed to some sort of regular low-level signal noise)? True PWM at that frequency would produce a horrific flicker at all sub-max levels. I've actually seen that a couple of times in the early days of multi-mode lights, and it wasn't pretty. But a low intensity signal at that frequency could well be invisible in actual use.Nicely done (as usual) I've been measuring these lights as well, but in my samples the PWM is very different at 71.4Hz and don't change frequency. I wonder if they have updated the driver or if they have used different drivers in different batches.
