Nitecore's black EC4GT LED Flashlight utilizes a new more energy-efficient Cree LED that maintains the maximum output of its predecessor while extending the runtimes at all outputs. It is die-cast from an aluminum alloy in two parts: the body and tailcap. Using this method reduces overall weight and size while also improving the overall structural strength and effectively making the entire body a heat sink, which helps to regulate the light's temperature - especially at high outputs.

Its CREE XP-L HI V3 LED produces from a minimum of 1 lumen to 1000 lumens on turbo mode. In addition to the five output intensities, the EC4GT has a disorientating strobe, SOS distress signal, and a signal beacon. The outputs and modes are controlled via two push button switches on the body, with instant access to the minimum & turbo outputs and the strobe mode. A lockout function that prevents accidental activation, its integrated battery status indicator ensures you stay appraised of the available power, and last-mode memory automatically returns the light to the last output that was selected.
