Anduril 2: Aux LED Voltage Colors

This page refers to features for Anduril 2.

You may be looking for the Anduril 1 manual or How to 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:

Voltage Color
> 4.4V white-ish (red+blue+green)
4.1-4.4V purple (blue+red)
3.9-4.1V blue
3.7-3.9V cyan (green+blue)
3.5-3.7V green
3.3-3.5V yellow (red+green)
2.9-3.3V red
< 2.9V black

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!
