It’d a really slightly nice blue, perfect for spending a night in an hotel. But: What current does it draw? I’m using my lights with 18350 with 1000mAh…
Umm. Definitly wasn’t my best idea, now long click (going back) doesn’t work any more. :person_facepalming: Modded back to normal switch…
I don't have one but if the picture on BG is right you have two blue leds, each with a 15k serial resistor (code 18C)
A blue led should be about 2.7V at low current, say you have 3.7V (batt) - 2.7V (led) = 1V remaining for the resistor so that is 1/15000= 67uA for each led
The overall current for the two leds is about (depends a lot on the battery voltage and real led voltage) 130uA = 0.13mA
1000mAh/0.13mA = 7700h = 320 days for draining the battery (rough approximation)
I see your last comment only now ... well at least now you know ;-)
