REI offers the Black Diamond Gizmo Headlamp in four colors (Dazzling Blue pictured) for $13.93 with free shipping. (Amazon offers it to Prime members for the same price in Ultra White.) That's tied with our expired mention from four days ago and the lowest total price we could find by $6. It features an output of 35 lumens to a distance of approximately 50 feet. It requires two AAA batteries, included.
