Update on the Wurkkos HD10 standby duration Test: it got to turquoise!

Hey guys!

https://www.reddit.com/r/flashlight/comments/1qtsboh/wurkkos_hd10_testing_the_duration_of_the_standby/

Wanted to close my project of determining the duration of the standby led of the Wurrkos.
It took 114 days to switch to turquoise. That is over 2700h of nonstop runtime.

I measured some data points along the way to extrapolate the runtime, but it is really hard because of little errors accumulate to big variances in runtime (in days). Also turquoise is supposed to need a lot (in percentage) more power, more used LEDs and also more power draw with other colors than blue.

I also don't have a realistic discharge curve of the AA Li Ion Battery (which is also hard, bc nobody measures it at this low amp draw) so i can only estimate of different LiIon AA batteries. It drops about 0,002V per day with the blue LEDs

But it probably took 1/3 of capacity of the 900mAh AA for 114 days.

and i based my guesstimations about the Capacity on this discharge curve:

sooooooo..it probably will take around a year of standby or 8800h 🙂
