The Princeton Tec Apex LED Headlamp will light up your outdoor world. The 3-watt MaxBright LED will shine a spotlight beam up to 180 feet away and the four UltraBright LEDs will cast a steady wide beam or flashing light out as far as 75 feet. All this power in a 10-oz. package that squeezes 72 to 200 (average 150) hours of light out of four AA alkaline batteries (included). The dual switch design allows easy access to the five modes. Submersible to 3-feet works with alkaline lithium or rechargeable batteries.
