This is the rechargeable flashlight that holds a charge for up to seven years. Unlike typical batteries that lose power during inactivity, this flashlight has specially designed Nickel Metal Hydride batteries that minimize power loss, ensuring reliable, full-power light for seven years on a single charge. The unit produces 200 lumens of bright light for up to six hours on a full charge, while three included AAA batteries provide 10 hours of backup power. A solar panel built into the handle recharges the batteries in natural or artificial light, or the unit can be recharged using the included AC or DC adapters. The flashlight is made from impact resistant ABS, it is 100% waterproof, and floats for easy retrieval if dropped overboard while boating. With an adjustable handle. 10" L x 7 3/4" W x 7 3/4" D. (1 1/2 lbs.)
