Yukon HL This all-LED headlamp offers extreme brightness and beam distance that rivals the high output typical of incandescent halogen and xenon bulbs. The Yukon HL features a Maxbright LED and 3 Ultrabright LEDs. Switch to the 3 LED mode when you require long burn time, and use the 1 watt LED for spotting at a distance. By using an all LED system, you eliminate the concern of bulb failure. The compact battery pack is mounted onto sturdy elastic webbing that offers ample adjustment for a comfortable fit. Specifications Power 78 Lumens Lamp 1 Maxbright Led, 3 Ultrabright LEDs Burn Time 120 Hours Batteries 3 AA Alkaline Weight 228 Grams UL Rating Approved Class I Division 2 Groups A, B, C & D Class II Division 2 Groups F & G UL Temp Code T3 Technology 3 Ultrabright Leds The highest quality LED available, the Ultrabright LED is bright and effi cient. 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. 3-Aa 3 AA Alkaline Lumen 78 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. 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. UL Certification 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 (++). 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. Weight - 228 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.
