Built for outdoor use, so it's perfect for camping, hunting, and other activity, the Coleman 4D Rugged Personal Size Lantern sheds 140 lumens of light on the High setting. Sporting a 7-watt fluorescent twin U-tube for a brighter, whiter light, the lantern runs cool to the touch for safety. It operates on 4 D batteries (not included), running for up to 23 hours on Low and 14 hours on High. Bulb replacement is a snap, thanks to the quick-release system. The Lantern's rugged design is weather-resistant and shatter-resistant, including a non-slip, rubberized handle for comfortable carrying, and heavy-duty thermoplastic and rubber construction so it stands up to heavy use in the outdoors. Lantern measures approximately 11” x 7” x 7” and weighs 1.81 pounds without batteries.
