2 Separate Buttons (one for each color), ideal for astrophotography & night photography. Button 1 for: Red Light Button 2 for: White Light Why Red-Light: It takes about 20-30 minutes for your eyes to fully dark adapt when doing photography at night. Red light does not mess with that process. Turn on the white light and you have to start dark adapting all over again. Why Separate Buttons for White/Red? One of the most frustrating things is for someone to accidentally turn on white light and ruin the dark adaptation of the whole group. The problem is some headlamps make you cycle through all the white light settings to get to the red LED. That is a terrible design for night photography. So the most essential feature for a night photography headlamp is a separate button to turn the red LED on and off.
