This cordless, weatherproof lamp provides bright reading light anywhere outside without requiring proximity to a power outlet. The lamp's four lithium-ion batteries provide up to eight hours of light after a 12-hour charge via the included AC adapter. The lamp has 48 LEDs that cast bright white illumination without the glare and distortion produced by an incandescent bulb's yellowish glow. A flexible gooseneck can be raised, lowered, or twisted for optimal positioning over a book. Its sealed steel body and hard plastic shade protect the lamp from rain, wind, and sun. LEDs last up to 50,000 hours. 54 1/2" H x 10" Diam. (12 3/4 lbs.)
