The LED Lenser V8 Photon Pump Torches from LED Lenser. Our V8 offers more than 200 hours of light with one set of batteries, and its diode has a service life of 100,000 hours and is the first to be equipped with gold-plated contacts, Crystal reflector tube system. High intensity light chip. Length: 6.5cm. Batteries included 3 x AG13. LEDs offer these advantages over conventional incandescent bulbs: Incredibly energy efficient. Longer lasting. More compact. More durable. The LED Lenser advantage. Crystal Reflector Tube System Led Lensers reflector tubes are lined with Italian crystal and precisely shaped to pump up the light produced by the LED for a broader, more powerful beam.Prism Reflector System: LED Lensers prism reflector solves the traditional problem with LEDS: intense up-close, but lacking beam depth and distance. Our patented system harnesses each LEDs power and drives it forward in a beam like traditional incandescent torches, but with all the advantages of LED technology.
