Acebeam D20 2.0 Dive Flashlight
The Acebeam D20 2.0 is a professional dive flashlight built around a Luminus SFT40 LED delivering 2200 lumens through a focused 9° beam that reaches 500 meters underwater or on the surface. Engineered for serious diving, it is waterproof to a 200-meter depth with dual O-ring seals, and its AL6061-T6 aerospace-grade aluminum body wears a diamond-grade anti-corrosion oxidation finish that shrugs off seawater.
A SUS316 stainless steel side switch keeps operation reliable in saltwater, the ultra-clear AR-coated tempered glass lens passes 98.3% of the light, and a rechargeable 21700 Li-ion battery runs the light for up to 5.5 hours. From cave systems to wreck penetration, the Acebeam D20 2.0 is a compact, corrosion-proof workhorse.
