The E1L Outdoorsman is an ultra compact, dual-output, extended-runtime flashlight featuring a virtually indestructible power-regulated LED emitter and a precision Total Internal Reflection (TIR) lens. Select an output level with the pushbutton tailcap switch: press or click for a 3-lumen low beam for reading a map or navigating around a campsite; release or click off and press or click again for a 45-lumen high beam. The included battery will operate for up to 4 hours at the highest level or 48 on the low level. The E1L Outdoorsman's small size makes it light enough to clip to the brim of cap for hands-free operation.
