Why don't I see the red light when it's on?Updated 3 months ago

This is normal. The Blueprint 302 Laser Diode Cap is designed with built in safety sensors - it will only activate when it’s properly positioned on your head and automatically turns off if removed before your session ends. Because the lasers emit low-level red light at 650 nm, the glow can appear faint in a bright room, but the lasers are still fully active and delivering energy to your scalp.
