Black Diamond Cosmo 350 Dual‑Fuel Headlamp – Rugged, Reliable & Night‑Vision Ready
Engineered for maximum versatility, the Black Diamond Cosmo 350 Dual‑Fuel Headlamp delivers dependable lighting in a lightweight and rugged form—ideal for tactical use, outdoor adventures, and emergency preparedness.
With a powerful 350‑lumen max output, this headlamp features dual‑fuel capability, allowing you to run it on three AAA alkaline batteries (included) or upgrade to the Black Diamond BD 1500 rechargeable Li‑ion battery and charger (sold separately). This gives you the flexibility to choose between long‑lasting disposable power or sustainable rechargeable performance.
The intuitive dual‑button interface makes it easy to switch between lighting modes, including white proximity, distance, dimming, strobe, and red night‑vision with both dimming and strobe options. A built‑in digital battery meter lets you monitor power levels in real time, while the digital lock mode prevents accidental activation during storage or transit—avoiding unwanted battery drain.
Built to endure challenging environments, the Cosmo 350 is IPX8‑rated, meaning it’s fully waterproof and submersible up to 1.1 meters for 30 minutes. Even if water enters the battery compartment, the headlamp will continue to function—just ensure it’s fully dried after exposure.
