The brightest headlamp in their professional series, Princeton Tec’s Apex LED Headlamp has been a favorite of extreme outdoor adventurers and cavers for years.

The Apex LED Headlamp incorporates a high-output Maxbright LED for intense, long-range spot lighting and four Ultrabright 5mm LEDs for wide-angle, close-in lighting. The focused narrow beams create a long-throw spotlight that’s ideal for night hiking and search and rescue, while the focused wide beams simulate normal daylight conditions so you can take advantage of your peripheral vision. Dual switches on the headlamp’s body make it easy to adjust the lamp’s brightness, beam width, or both to best suit your needs in a given situation. The headlamp’s impact-resistant plastic body offers strong resistance to weather and environmental conditions and is waterproof down to one meter for up to 30 minutes. A longtime favorite of extreme outdoor adventurers and cavers, the APEX headlamp is ideal for camping, caving, climbing, paddling, and working outdoors.

  • Maxbright LED emits smooth, powerful white light for intense long-range spot lighting
  • Ultrabright LEDs emit smooth, wide-beam white light for wide-angle, close-in lighting
  • Built-in heatsink protects LEDs from overheating and enables them to burn at extreme brightness levels for longer periods of time
  • Dual switch design allows easy access to all four brightness levels and the emergency strobe function
  • Level 2 waterproof, impact-resistant plastic body provides waterproof integrity down to 1 meter for up to 30 minutes
  • Additional strap on top holds light securely in place; rear-mounted battery pack holds 4 AA alkaline batteries (included) and features padding for comfort
  • Ideal for camping, caving, climbing, paddling, and working outdoors

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.

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.

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.
