The Apex is Princeton Tec's professional-level headlamp that everybody can use. Cavers, night runners, adventure racers and weekend campers alike love the super-bright, 200-lumen illumination the fully waterproof Apex brings. You've got one Maxbright LED and 4 regulated Ultrabright LEDs so you can choose between a powerful spot beam or a bright flood light. The 4 side LEDs are also available in red or green to suit your needs. An ingenious heatsink in the rear keeps your light burning cooler and longer, and the light is regulated so there is no dimming, it's on until it's off. Though with 5 different modes and burn times of 150 hours, you don't have to worry too much about that.
