These lamps are technological dynamite. Their core piece is the Advanced Focus System and lens technology. A double-shell reflector-lens allows for stageless transition from broad floodlight to a sharply focused long-distance beam. The initial appeal of the new LED LENSER flash lights lies in its grace and dynamic elegance. But what's inside the beautiful housings is even more enthralling: These lamps are technological dynamite. Their core piece is the Advanced Focus System (starting with LED LENSER® P5). This lens technology, represents a milestone in the history of artificial light. Press the push button gently to make the white beam of LED LENSER® appear before your eyes like a cathedral of light. A double-shell reflector-lens (patent pending) allows for stageless transition from broad floodlight to sharply focused long-distance beam. Most of these lamps are equipped with a new generation of 3 watt chips. The LED LENSER® P14 features a Dynamic Switch (3 levels of brightness) and a 39 mm reflector-lens. In combining them with the new Super Light Chip, LED Lenser have achieved a level of focusing that sends an incredibly sharp light beam into the night. This lamp is world class. But there’s more: When you move the lamp head, the concentrated beam wondrously expands to form a wide, homogeneous circle of light that enables you to evenly illuminate large areas. The LED LENSER® P14 is operated with 4 alkaline Mignon batteries that doesn't really cost much. Hence, this lamp not only sets new standards in luminous efficiency and focusing, but also in economy.
