The NiteCore MT40 Flashlight is an ultra-high intensity hand-held searchlight built for power, flexibility and versatility, capable of reaching a max output of 860 lumens of light from its premium CREE XP-G R5 LED. This handheld search flashlight features four brightness levels and two operating modes easily accessed through the bezel ring twist activation and the pushbutton tailcap switch. The NightCore MT40 Flashlight lets you instantly switch into Turbo Mode for a pre-set output (up to 860 lumens) or to the User-Defined Mode to change the light level and function to suit your requirements. Compact size, combined with high performance and super-solid construction make the NiteCore MT40 MT-Series Flashlight an ideal EDC flashlight - it weights in at only 245 grams, and can be easily clipped onto a shirt, belt loop or bag with the two-way anti-roll titanium plated stainless steel clip. This powerful full-size flashlight draws its energy from four CR123 batteries, giving you a commonly available power source, or two 18650 batteries - and at lower light settings, can run for up to 24 hours on a single set of batteries. The Nitecore MT40 LED Flashlight uses a custom-designed high efficiency reflector to provide a versatile beam profile that provides plenty of floodlighting and a long throw distance - up to 363 meters - that make it ideal as a security light or search light.
