A reliable dive light is essential for underwater safety. One of the factors that determine the reliability of a dive light is its lumen output. The more lumens a dive light delivers, the brighter it is. Basic dive lights have a lumen output ranging from 500 to 1000, while medium-range dive lights have 2000 to 3000 lumen outputs. The most powerful lights can reach 25,000 lumens. But for divers of all experience levels, a good medium-range light is a perfect addition to their diving gear.

Here are some of the best 2000-lumen dive lights on the market today.
