Princeton Tec - Apex Headlamp

The Apex from Princeton Tec is the brightest in the professional series. Apex has been a favorite of extreme outdoorsmen and cavers for years. The pinnacle of waterproof LED headlamp design, Apex incorporates a single Regulated Maxbright LED plus four Regulated Ultrabright LEDs. Apex is capable of a powerful spot beam or a bright flood, and two switches make changing modes intuitive. The four Ultrabright LEDs come in your choice of red, green, or white. Proprietary heatsink technology allows the LEDs to burn brighter and longer. Apex is compatible with alkaline, lithium, and rechargeable batteries.

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.

Underwriters Laboratories Inc. (UL) is an independent, not-for-profit product-safety testing and certification organization. They have been testing products for public safety for more than a century. In order for a product to bear the certified UL Mark, it must pass all UL requirements at their testing facility. Princeton Tec lights that are UL certified fall into one of the following classifications: Class I – Division II – Groups A, B, C, & D or Class II - Division II – Groups F, & G. Refer to the comparison chart in the rear of the catalog. Class I – Division II – Groups A,B,C,& D will be noted with one (+) Class II – Division II – approved for Groups F, & G, will be noted with two (++).

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.

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.

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.

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.

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 effi ciency and brightness of Ultrabright LEDs.
