Anduril 2: Aux LED Voltage Colors Reference
This page refers to features of Anduril 2.
You may be looking for the Anduril 1 manual or Check if you're running Anduril 1 or 2.
The Anduril 2 Manual mentions the Aux LED Voltage mode colors:
In voltage mode, the colors follow the same sequence, in the same order as a rainbow… with red indicating a low battery and purple indicating a full battery.
If you’re like me, you may not actually know what the colors of the rainbow are (doh!). No fret, here’s a handy reference with colors of the rainbow which represent the battery level from full down to empty:
I also took a look at the Anduril 2 source code to make sure I knew what each color means in terms of volts. These were confirmed for me with a comment in r/flashlight by u/enter_user_name:
|> 4.4V||white-ish (red+blue+green)|
u/Nelson_uk also posted a great video testing the different colors as the light goes through the different voltages.
Hope this helps you out in using your fancy enthusiast flashlights. Gotta love them Aux LEDS!
