The CORE Equipment 1500 Lumen Rechargeable Flashlight is designed for high-output illumination with adjustable performance for different environments. It uses a CREE LED that delivers up to 1,500 lumens on high, with an approximate 2-hour runtime, and 125 lumens in low mode, with extended runtime up to 21 hours. The beam can reach distances of about 167 meters on high, and an auto-brightness feature adjusts light output based on surroundings to optimize visibility and efficiency. The flashlight is powered by rechargeable lithium-ion batteries and recharges via USB, and it can also function as a power bank for small devices. Built for general outdoor use, home projects, and emergency situations, it combines multiple light modes, long battery life, and consistent LED performance in a handheld design.
