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.

This beam pattern is an excellent choice for multipurpose activities. At close range, focused wide beams simulate normal daylight conditions and allow you to take advantage of your peripheral vision.

XENON BULBS come closest to replicating the color temperature of daytime light. They also generate about twice the brightness and consume about half the power of traditional halogen bulbs.

Halogen and Xenon Lights are well-suited to applications where a long-throwing beam is required such as caving and search and rescue. They are less desirable for longer-term, backcountry uses, where weight and battery efficiency are a must.

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.

The highest of Princeton Tec’s ratings, Level 3 is assigned to lights that offer a degree of water protection equivalent to IPX8 in the International Electrotechnical Commission (IEC) standards. Lights rated at Level 3 provide waterproof integrity for continual submersion in water at depths down to 100 meters.

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.

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.
