This is the world's first sensor LED flashlight. The advanced technology sensor strip makes turning the light on or off so easy, so effortless. No pressure, no fumbling, no more broken finger nails! Just hold the sensor strips to turn the light on. Two super bright, white LEDs produce a clear crisp beam of light, that can be seen more than a mile away. LED bulbs are energy efficient and never need replacing, lasting for 100,000 hours. An override button, located on the bottom of the flashlight keeps power off until you want it on.
