At less than 4 inches in height and only 2.5 ounces in weight, the ML4 is ultra-compact, allowing you to take high-power lighting anywhere you go. Thanks to our latest micro-prism technology, the ML4 provides efficient, glare-free soft, warm white light distribution up to 300 lumens. It's powered by an included rechargeable battery, but can be used with a standard AA alkaline battery when a power source isn't available. The carabiner snap hook provides flexible usage and attachment options, such as on a backpack or hanging from the roof of your tent. Powered by nine LEDs with five light functions, and featuring a red light mode, this versatile lantern provides the perfect illumination for the tent, campervan, attic, shed or anywhere else you need bright, compact area lighting.
