EVOLVA FUTURE TECHNOLOGY T20 IR 38mm Lens Infrared Light Night Vision Flashlight Torch

INVISIBLE IR LIGHT: Evolva T20 is NOT a regular flashlight with white LED for general lighting purpose. Utilizing Osram Oslon infrared light black 850nm LED emitter, Evolva T20 emits invisible but high power IR light with more than one watt of optical power. Please beware that: you won't see any light with your bare eyes (only a small and faint red glow on the Osram LED to show you that the torch is on). LONG RANGE ILLUMINATION: Evolva T20 utilizes the OSLON IR black infrared LED - today's smallest and most advanced infrared LED with high efficiency, low thermal resistance, and more than one watt of optical power. T20 can produce a powerful punch with approximately 150 meters range (approx. 165 yards) with focused beam. With the latest chip technology, integrated lens and an excellent package, lifetimes of up to 50,000 hours are easily obtainable. ASPERICAL LENS: 38MM Lens rotary focusing function enable the ability to focus in for a tight spotlight or back out for a flood effect, especially designed for long range illuminations. T20 can illuminate much farther with focused beam, compared with illuminator without focusing functions. CAN ONLY BE POWERED BY 18650 BATTERY, NEVER USE CR123A: With operating voltage of 3.7-4.2V, T20 is powered by 1 x 18650 Li-Lon rechargeable battery. T20 cannot be powered by 2 x CR123A battery, as 2 x CR123A with 6V voltage will burn the driver board. Please carefully select the 18650 with genuine core as there are many 18650 batteries on the market with fake cores and of inadequate quality. SOLID AMD COMAPCT: Body made of Aircraft Aluminum Alloy.
