The Apex combines proprietary Princeton Tec optics and a high-output, three-watt
Maxbright Rebel LED for an incredibly long-range LED headlamp with 200 lumens of
brightness. For wide area illumination and longer running time, select the array of four
ultrabright LEDs. The Apex, which comes with a battery power meter, is current regulated for constant light output, and the proprietary heat regulation
system allows a brighter light and a longer burn time. Two switches allow independent control of the three-watt LED or the LED array. Runs on four AA
batteries (included) and can use alkaline, lithium or NiMH batteries. Maximum burn time: 150 hours. Waterproof to one meter for up to 20 minutes.
