The Princeton Tec Apex Headlamp is the biggest and brightest headlamp in their professional series and has been a favorite of extreme outdoorsmen and cavers for years. This Princeton Tec headlamp features a single Regulated Maxbright LED partnered with Four Regulated Ultrabright LEDs to provide either a powerful spot beam or a bright flood, and switching between the two is incredibly easy. The proprietary heatsink technology allows the LEDs to burn brighter and longer. The Apex headlamp is truly the pinnacle of waterproof LED headlamp design, and is compatible with alkaline, lithium, and rechargeable batteries.

FEATURES of the Apex Headlamp by Princeton Tec

  • Weight - 279 grams: Princeton Tec's advertised product weights always include batteries. For many products, battery weight is a large percentage of overall weight. Weight can be significantly reduced by using lithium batteries in lithium-compatible products.
  • Waterproof - Level 2: Princeton Tec's intermediate rating, Level 2, is assigned to lights that offer a degree of water protection equivalent to IPX7 in the International Electrotechnical Commission (IEC) standards. Lights rated at Level 2 provide waterproof integrity down to 1 meter for up to 30 minutes.
  • Multiple Modes: Multiple settings on many of our products give you the flexibility to adjust your light's brightness and/or beam width to illuminate greater distances or to conserve battery power, depending on your needs.
  • Multiple Beams: This beam pattern combines focused narrow and focused wide beams to allow for the most versatility. At close range, the focused wide beams simulate normal daylight conditions so you can take advantage of your peripheral vision. The focused narrow beams create a long-throw spotlight ideal for night hiking and search and rescue.
  • Maxbright LED: The highest quality LED available from Lumileds, Princeton Tec's Maxbright LED is extremely bright and efficient. This single LED emits a smooth, powerful, white light useful for a wide range of tasks. Princeton Tec uses collimators or reflectors with the Maxbright LED depending upon the application.
  • Lumen 130: The light output of Princeton Tec lights is measured in lumens. A lumen is unit derived by the International System of Units (SI) for measuring light output.
  • LED Optic Collimator: A collimator gathers all available light from an LED in the form of scattered rays and re-emits the light as parallel rays, making it more optically efficient than a standard reflector. Princeton Tec calibrates each collimator to the type of LED and application of each light. With proprietary optimized collimator / lens systems, Princeton Tec continues to advance LED technology.
  • Heatsink Technology: Princeton Tec has developed proprietary ultralight heatsinks to protect LED products from overheating. Even though LEDs operate at much lower temperatures than traditional incandescent bulbs, they still generate heat. If this heat is not dissipated, the LED will suffer irreversible damage. By using heatsinks, Princeton Tec lights can burn at extreme brightness levels for long periods of time. The heatsink may be incorporated internally or externally depending on the product and its application.
  • Battery Power Meter: The battery power meter provides you with continuous feedback on the condition of the batteries, indicating high, medium or low battery life. This information allows you to make educated decisions about changing batteries or packing spare batteries.
  • 4 Ultrabright LEDs: The highest quality LED available, the Ultrabright LED is bright and efficient. The smooth, white, wide-beam light emitted by Ultrabright LEDs is ideal for close to mid-range tasks. Ultrabright LEDs are usually grouped together to offer a more powerful light source. Advances currently underway will continue to improve the efficiency and brightness of Ultrabright LEDs.
  • Ideal Uses: Camping, caving, climbing, paddling, and work.

Rated 5 out of 5 by from Great Headlamp, beats Black Diamond Icon I really enjoy headlamps, and really enjoy bright headlamps; needless to say I really love my Apex. The fit is comfortable, heavier than Icon, but you also get one more battery which equates to longer life brighter light. Been using mine for nighttime biking and it does a good job of showing me the trail on a moonlit winters night, even when I only use the 4 LED's on the side on their brightest setting. When you use the main bulb does it ever light up the night! I also like that you can use lithium batteries which allows for longer max burn times and better cold performance. While the Icon is limited to alkaline batteries.,,

Rated 4 out of 5 by from I let my life depend on this dude! I use this light normally as my primary light while I'm caving. I did have an issue with one, the o-ring was messed up from factory and it got water inside, but they replaced it! Other than that this light works great! It puts out plenty of light and with the spot beam and wide beam options you always have just the right light for what ever the situation! We have two of these in our caving group and we both love our light and trust it not to fail...or we'd be left in total darkness back off in a cave! Wish it was dive proof, but I never really go deeper and 1-2 feet underwater with it anyways. It's lasted me almost a year and still doing great! Money well spent!

Rated 5 out of 5 by from Turn night into day This light will last thru the night, all night on low. Then ramp it up to high when looking for that elusive checkpoint. It turns the woods to daylight with the press of a button. Also waterproof, not just resistant, so it will keep working if conditions are terrible.
