Konus KonusLight-5K Features The Konus Optics KonusLight-5K Flashlight delivers a base output of 2500 lumens from its single LED emitter with an instant Turbo mode that doubles output to 5000 lumens for a short burst of maximum brightness. The flashlight offers four operating modes including a 100 percent setting that shuts off automatically after two hours a 40 percent setting lasting eight hours and a 5 percent low setting that extends runtime to roughly ten hours. The Turbo setting itself runs for only ten seconds giving a quick flash of extra light without draining the battery. A zoom function lets the user adjust the beam from flood to spot as the situation requires. Built with an anodized aluminum body the KonusLight-5K is both waterproof and compact enough for a pocket or a pack pouch despite its powerful output. It runs on a single rechargeable 20650 lithium-ion battery included with the light and recharges fully in about five hours using the supplied USB cable. The manual push-button switch keeps operation simple in the field or in low light situations where quick activation matters. At roughly 300 grams this flashlight is a practical choice for hunters outdoorsmen and anyone who wants serious output in a small rechargeable package.
