The Saint headlamp produces a wide, variable-output beam optimized for your field of vision. Adjustment from 0 to 100 lumens is done with one hand—even cold or gloved—operating a dial integral to the light assembly. Made from hard-anodized aerospace aluminum, the Saint is lightweight yet built for the rigors of caving and mountaineering, and is submersible to 3 feet for up to 30 minutes. The fine-mesh headband features moisture wicking Breathe-O-Prene pads that provide unmatched comfort and dryness, and a built-in system to keep the power cables secured and out of the way. Saint is dual-fuel capable—it can run on one, two, or three 123A lithium batteries, or two AA alkaline batteries. Included is a single-battery adapter cap that holds one 123A battery and screws directly into the Saint"s light assembly, enabling you to remove the battery pack/cable system. This effectively converts it into our compact, lightweight version of the Saint, the Saint Minimus.
