This headlight is an innovative hands-free light source that solves all your lighting needs for camping and exploring. Switch between using 2 LEDs, 4 LEDs, or 8 LEDs by clicking the weatherproof button switch on the top of the unit. Use 2 or 4 LEDs for close-up work to save power, and switch to 8 LEDs for a stronger, longer beam. LEDs provide a bright, evenly distributed beam over a short distance. They are incredibly efficient, resulting in exceptionally long battery life. The LEDs themselves don't burn out and will last for over 10 years if powered 'ON' continuously!
