Are you looking for a compact and extremely durable headlamp? Do you want reliable white and red light with long runtime and constant output? Do you need a headlamp suitable for military, police, hunting, and outdoor use? Then the Fenix HM51R Ruby V3.0 is exactly what you need. This headlamp is based on the proven HM50R platform but offers higher output, a higher-capacity rechargeable battery, a warmer neutral light tint, and expanded red light modes.
