Unfortunately, this is something that we are not able to do anything about it.
The LEDs have different VF value, thus the brightness of the LEDs can not be the same, especially at low current. As you can see, even our advertising photo have different LED brightness.
Even the same type of LEDs, from the same reel, next to each can have different VF. The white LED tend to be more uniform, the warm LED has more chance to have different VF.
I have 2 D4V2 Ti with cool white button LEDs and they are perfect.
I thought that with the warm emitters the warm button would look nice, and it does. But the brightness difference bugs me too. A pity it cannot be helped.
I have cool white switch LEDs, but one was significantly warmer than the rest. I turned the switch LEDs off in the code and reflashed. I found that I actually like it better without them on. The switch LEDs were very bright at night.
Edit: I’m pretty sure I just commented out “#define USE_BUTTON_LED” in cfg-emisar-d4v2.h.
Even on low mode they were too bright? I set mine hi or lo according to the light. My D4SV2 is bright on hi, but I like it that way around the house or on the nightstand.
Not sure what you mean by that. It's a cfg file - stands for configuration file, and that's what it does - configures the firmware. For Anduril, it has driver and light specific settings, and user preferences.
