Meet the Blackfire Clamplight Backpack: a backpack lantern that you can take with you to the outdoors conveniently. It clamps anywhere and offers 4 lighting modes: high lantern, low lantern, strobe, and flashlight. The Clamplight Backpack pivots, stands, and clips on to your backpack via the fold away aluminum carabiner clip. The device uses CREE LEDs and can run for 28 hours (lantern mode) using three AAA batteries.
The Clamplight Backpack is IPX4 water resistant, so it is ready for your outdoor adventures. It can provide up to 125 lumens of light when used in lantern mode. Not too expensive either.
