Being a collapsible LED lantern, it fits perfectly under a bed or in a backpack and offers up to 12 hours of illumination. Also because the lamp weighs in at only 4.8 ounces and is completely weather resistant, you'll have reliability during the most chaotic scenarios without having to worrying about it slowing you down.
"Illuminate your tent with the Coleman CR123A Lithium Pack-Away Lantern. a mini-carabiner hangs this lightweight lamp from the roof of your backpacking tent so you don't have to hold it up yourself as you read your fairly trashed trail map or fairly trashy romance novel. Three positions let you choose the appropriate light setting, and up to 12 hours of illumination brighten your dark nights or storm-confined days. This collapsible lamp packs away break-free, thanks to a rubberized outer shell. *3 CR123 batteries included."
