Designed to meet the rigorous reliability and durability requirements of the Military, Law Enforcement, and personal defense user, each NovaTac model is available with maximum output of 120 lumens. Lightweight, easy to use and virtually indestructible, the NovaTac EDC flashlights have an intelligent power supply that linearly reduces output as the battery starts to run down, reducing the risk that you will ever be left in the dark. 3 or 4 brightness levels can be selected to meet your mission requirements or to conserve power. Choose your model and your brightness. It could be the last flashlight you will ever need.
