I have a Zebralight since more than ten years now. Never had an issue and I use it very often (even several days per week in the workshop when I´m at the lathe or mill). Just recently I bought a backup and therefore had a closer look at the market. It is the lightest headlamp on the market and it is the only lamp with no nonsense extras like a usb/c charger and so on. A red light on a headlamp is certainly a good thing but I never felt the need for it.
