This is a keychain-size flashlight with big-light power. It features the classic look of the company's original Solitaire flashlight introduced in 1988, and it works in the same simple way. Just twist the head to turn on, turn off and focus spot to flood. Thanks to a new, state-of-the-art LED light engine, you get something you just wouldn't expect to see coming out of a flashlight so small; a blast of power that can light up an object at the far end of the parking lot 46 meters away! The flashlight comes with one AAA battery (which should run the flashlight for about 1 hour 45 minutes), and it has a keychain lanyard.
