Ultrabright LED

Ultrabright LED
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.


Glossary of Terms

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.
Dimmable LED
This advanced circuitry allows selection of whichever power level suits user requirements.
Focused Narrow Beams
This pattern creates a long, powerful beam of light excellent for illuminating distant areas. The resulting long-throw spotlight is especially well-suited for night hiking and search and rescue.
Focused Wide Beams
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.
Halogen Bulbs
Halogen work in exactly the same way as traditional incandescent bulbs found in your home with one major difference: they contain halogen gas instead of nitrogen or argon. This difference allows the bulb to burn brighter, more efficiently, and for longer periods of time. The bulb needs to be replaced less frequently since filament life is extended.
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.

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.
Lumen
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.
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.
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.
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.
Regulated LED / Constant Brightness
Princeton Tec lights that feature regulated LEDs have a sophisticated regulating circuit that maintains initial brightness as long as the batteries have sufficient voltage. Traditional lights are very bright initially, but immediately begin to dim and continue to dim until the batteries are drained. Constant Brightness is a term used to describe products that have regulated LEDs.
UL Certificatio
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 (++).
Ultrabright LED
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.
Waterproof - LEVEL 1
Level 1 is assigned to lights that offer a degree of water protection equivalent to IPX4 in the International Electrotechnical Commission (IEC) standards. Lights rated at Level 1 are designed for water resistance to splashing and quick dunkings. If a light with a Level 1 rating is accidentally submerged for a longer period of time, the batteries should be removed and the cabinets should be carefully inspected for signs of battery leakage. If water has entered the housing, the light should be dried and batteries replaced.
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.
Waterproof - LEVEL 3
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.
Weight
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.
Xenon Bulbs
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.
