The Surefire Maximus Vision is virtually identical to the original Surefire Maximus but it produces warm-colored light-similar to the color produced by a tungsten lamp-that can be easier on the eyesight of some users, particularly when the headlamp is used for extended periods of time. This light color also effectively cuts through haze and renders colors in nature in a way some prefer. Its beam color may be warmer, but it has the same useful shape as the original: wide and evenly distributed, with plenty of reach and peripheral illumination. With variable-output settings up to 450 lumens; a rechargeable lithium-ion battery; rugged, lightweight magnesium construction; and a beam that helps reduce eye fatigue, Maximus Vision is an outstanding choice for extended-use applications.
