Saint's solid-state LED produces up to four times the light output of a typical four-D-cell flashlight, with 144 hours of runtime at its lowest setting. A variable light output dial allows one-handed selection of any light level from 1 to 100 lumens and it features an emergency SOS mode. Saint's headband system includes washable moisture-wicking Breathe-O-Prene pads, and micro-fiber straps with low-profile buckels and smooth stitching to eliminate hotspots and pressure points. The dual-fuel battery pack accepts 123A lithium or AA alkaline batteries. This is Saint.
