The Black Diamond Storm Duel-Fuel 450 Lumen Headlamp is for the technical consumer who wants the best, brightest, most waterproof, feature-rich headlamp to use for fast-paced, extreme-environment activities.

An added benefit is the DF, or duel-fuel, feature, which allows the headlamp to run on alkaline batteries if caught away from a power source for a long expedition. Alkaline cells are included.

Settings include full strength in proximity and distance modes, dimming, strobe, red, green, and blue night vision, and lock mode. PowerTapTM technology allows instant transitioning between full and dimmed power.
