Got mine today.
I discovered that if you double tap quickly the top button, you can actually change the tint of the light. Normally you have a very warm and a very cool white option only.
Double tap top button and then hold the top button it will slowly transition to cool white and warm white until you let go. Then press bottom button (goes into red and then red flashing then off) and it saves that colour selection.
Ahhhh! So by going through the red light selector on the bottom it locks in the preferred tint, Sweet! I’ll try to remember that, see if I can get it to cling to the webbing I call my mind….
