Focused light for diving
The smooth reflector and clear glass lens help form a strong, focused beam. The lens has an anti-reflective coating and 98.3% light transmission. In addition, the light uses steady output control and heat protection to manage brightness and surface heat.
Before every dive, inspect the body, lens, seals and switch. Also make sure the light closes fully and test every mode before entering the water. Rinse the Acebeam D20 diving flashlight with fresh water after salt-water use, then dry it before opening or charging.
Finally, use this light as part of a safe dive plan. Carry the backup lighting required for your dive, follow the stated depth limit and maintain the seals as directed by the maker.
