Fifth time's a charm? Maratac thinks so. This fifth version of the popular copper AAA flashlight features an Ultra High 92 Color Rendering Index in a neutral white tint of 4000K, a new Nichia 219 LED, and even brighter output than before (up to 170 lumens). After much feedback, the sequence has also been changed to medium, low, high as well. The Maratac Copper AAA Flashlight is a small, durable, powerful light which has a body constructed purely out of copper and runs off a single AAA battery. With a bulb life up to 50,000 hours and three levels of brightness, it is a powerful tool for EDC, camping, or a professional toolbox.
