The Triode gets its power from the lone AAA battery we include with purchase. The L.E.D. bulbs sustain peak brightness for longer periods—casting a wash of light out some 50 feet—and never need to be replaced.

The over-the-head strap assures you that the Meridian will ride steady on your head without slipping down. The three AA batteries (which come with the Meridian) secure at the back of your head. All in all, a smart lighting solution.

The terms ultralight and compact are redefined with the Scout headlamp. Weighing approximately 45 grams it’s small enough to fit into your pocket and forget it’s there. The unique hinged lamp housing allows you to direct light where you need it. Or you can easily detach the light from the head strap for use on your cap backpack strap belt or other gear. The Scout sports three levels of light output and two emergency signaling modes which are quickly accessed by a single button. Four tiny lithium coin cell batteries keep the Scout ultralight ensure reliability in extreme cold weather and pack up to 48 hours of burn time.

This all-LED headlamp offers extreme brightness and beam distance that rivals the high output typical of incandescent halogen and xenon bulbs. The Yukon HL features a Maxbright 1 watt LED and 3 Ultrabright LEDs. Switch to the 3 LED mode when you require long burn time and use the 1 watt LED for spotting at a distance. By using an all LED system you eliminate the concern of bulb failure. The compact battery pack is mounted onto sturdy elastic webbing that offers ample adjustment for a comfortable fit.

The combination of a one-watt Maxbright LED and Princeton Tec's proprietary optics offers unprecedented brightness and beam smoothness in an ultralight 3-AAA platform. The Eos is optimal for both localized needs and spotting at a distance. We recognize that different amounts of light are needed for different conditions and situations— that's why we equipped the Eos with three brightness levels and a blinking emergency/signaling mode. The Eos is ready for adventure with its impact-resistant design.

A lightweight affordable 2-AA incandescent headlamp the Quest is perfect for the novice or occasional outdoor enthusiast. The incredible quality and value is perfect for everyday needs from weekend camping trips to home improvement projects. The Quest includes one high-output Halogen bulb and one long-burn bulb.

Classic design traditionally used by military forces for its precisely accurate bearings in land navigation and directing artillery coordinates. Heavy-duty powder-coated aluminum housing.

The Apex is the pinnacle of waterproof LED headlamp design boasting up to 60 lumens of output. With its four light levels safety flash mode and impact-resistant design the Apex is an ideal headlamp for any hardcore adventure. The Apex combines a regulated three-watt Maxbright LED with four regulated Ultrabright LEDs for Constant Brightness on all modes. Switching modes has never been easier —the dual switch system allows you to independently control the intense smooth long-range lighting from the Maxbright LED and the wide-angle close-range lighting from the four Ultrabright LEDs. Proprietary heatsink technology allows the LEDs to burn brighter and longer. The Apex is compatible with alkaline lithium and rechargeable batteries.
