The 10 Day Lantern.

Thanks to 12 bright, powerful LED bulbs, which use only a fraction of a traditional bulb's energy, this lantern provides up to 10 days of continuous light on only a single set of D batteries. This compact lantern is bright enough for reading while camping or during a power outage and includes a dimmer-style power switch. Its durable, water-resistant case features a built-in handle which can also be used to hang the lantern for hands-free lighting. The bulbs produce almost no heat, making this lantern safe for children--and uninteresting to insects. Requires four D batteries. 9" H x 6 3/4" W. (2 1/2 lbs.)
