No, you don't need a lantern. But you'll want this one. It's a kitchen light, campfire, and reading lamp wrapped into 4.4 ounces. And it's so packable that even our staff minimalists deigned to carry it. We love the adjustable LED, which dims for candlelight dinners or brightens for poker games. It collapses to four inches for packing (it's five and a half fully extended).
And during six months of testing, we never had a failure despite dropping it, leaving it out in storms, and carelessly cramming it into packs. Battery life is also superior: 11 hours on the brightest setting. Green bonus: A plug-in rechargeable battery pack (six-hour life) is now available as well ($30, sold separately). $30; 4.4 oz. with 4 AAA batteries; bdel.com
