The D30 is a professional diving flashlight designed for deep-sea exploration. Equipped with the high-performance SFT-90X LED, it delivers a powerful focused beam of up to 5,600 lumens, with a beam distance of 1,454 meters (on land) and a maximum tested depth of 100 meters. Its 5° ultra-narrow beam angle enhances water penetration, making it ideal for spotting marine life and navigating murky waters. Powered by 2 x USB-C rechargeable 21700 batteries, it runs for up to 5 hours in Low Mode(1,100 lumens), and you can swap them out when the battery level is low for extended use. Featuring a simple side switch, the D30 allows for intuitive operation, enabling divers to easily adjust brightness levels for various underwater conditions. Constructed from high-strength aerospace-grade AL6061-T6 aluminum alloy, its surface is treated with anti-corrosive oxidation, ensuring durability and resistance to seawater corrosion.
