The ring of LEDs makes this look like a classic UFO flying saucer. The "donut hole" center makes the saucer easy to hold and turn in your hand. This highly efficient light also can be used as a great portable lamp for camping, parties, picnics, etc. Includes a detachable hanger. Features a steady-on mode only. Uses 4 AA batteries (not included) which last for 30 hours. The LED bulbs will last a lifetime of use, more than 100,000 hours!
