UCO says:The Madrona+ Hang-Out lantern has a Magnetic lanyard hanging system that allows for quick attachment and removal. Place the lantern on its base for traditional use, or elevate from lanyard and hang from tent, tree or other object. Three super bright CREE LED's provide output of up to 300 lumens to light up your campsite. The Infinity Dial allows fine tuning of light output from low to high. This model runs on a 6400mAh Li-ION battery that is rechargeable and features an output as well.
