The Neptonics 860 Lumen Dive Light is great for spearfishing in holes and is extremely effective at spotting lobsters at night on the reef. The concentrated 8-degree beam really penetrates the holes that fish hide in. Made from solid aluminum, this 860 Lumen LED Dive Light is compact and powerful. The lifetime LED bulb produces a bright white light. The design makes this light bombproof and waterproof to 328 feet. The compact 5-inch-long design allows for it to fit comfortably in the hand. This dive light takes three AAA batteries. You may want to consider the optional rechargeable battery kit that takes the place of the AAA batteries. This rechargeable Samsung battery comes with a charger.
