Princeton Quad Tactical Headlamp
We prefer using both hands when we’re working, especially in the dark, and for that task lighting, we use the Princeton Quad Tactical Headlamp. This headlamp has a lot of cool features: it tilts easily, has multiple brightness levels, is molle-compatible, is waterproof to 1 meter if you drop it in the drink, and has interchangeable lenses in red, blue and green, to keep your night vision intact once you turn it off. All in all, a great headlamp and a valuable tool in an emergency situation.
From the manufacturers website:
Aiming to meet the highly specialized needs of both outdoor sportsmen and the US military, Princeton Tec created the tactical version of our popular Quad headlamp. The Quad Tactical augments the original Quad’s lightweight and durable design with three interchangeable lens covers which filter the four Ultrabright, regulated LEDs into red, blue or green light. Four Ultrabright LEDs provide a flood beam in multiple levels.
