The eGear PICO Lite projects a powerful 10 lumen beam up to 30 feet from an ultra-compact and tough cylindrical aluminum body weighing just two-tenths of an ounce. The PICO Lite is the ultimate reliable personal flashlight that's so small you can always have a light with you.Designed in collaboration with survival equipment authority Doug Ritter, the PICO Lite is constructed of rugged 6061 aluminum, anodized for added protection. It's water resistant to IPX4 international standard and has an unbreakable LED light source. The rotary bezel switch ensures it is all but impossible to turn on inadvertently, which means the batteries will still have juice when you need light.
