Acebeam D20 is an intensely bright and portable underwater scuba diving light. With 2700 lumens of output, it is powerful enough for every underwater task and will bring the ocean to life in a way that you have never experienced before. The smooth reflector directs the beam to easily shine through the dark and murky conditions while still having enough flood to see everything. The D20 is powered by an included Li-ion 21700 battery, but can also be powered by a single 18650 battery. The Acebeam D20 is built for divers that require a flashlight that can operate at depths of up to 200 meters, but can also be used on outdoor adventures. The D20 can compete with the best of the best on land or under water, making it a truly versatile flashlight! By Acebeam.
