An upgraded version of D20, D20 2.0 is a powerful, high-quality professional diving light designed for underwater lighting.

Powered by a single 21700 rechargeable lithium-ion battery, it can provide 5.5 hours of ultra-long continuous lighting. With a beam angle of 9°, this light effectively allows you to focus the beam to explore undersea environments such as caves and shipwrecks with ease, and can also illuminate colorful marine life from a long distance.

D20
The main power button is raised and oversized on purpose, making it super easy to locate and click by feel alone when wearing thick neoprene diving gloves underwater. The solid casing holds up perfectly to water pressure. The finish is excellent as usually! Great torch for outdoor as well

Looking forward to another holiday
The D20 2.0 is an absolute game-changer for underwater exploration. I love the feel of smooth but rugged body that stands up perfectly to corrosion and the pink color is amaziiiing !! It feels super solid in hand

Stunning
I have the black Acebeam D20 v2 and love it for its compact power and waterproof reliability. Planning to grab the purple one for my girlfriend soon, those gorgeous color options like black and pink/purple really make D20 stand out with beautiful finishes. The sleek anodized colors give each light its own personality while keeping that pro dive torch toughness. Purple and pink would be perfect match for her gear, looks stunning and unique

Also for hunting purposes
Even though the D20 is designed as a dive flashlight, we tested it at a hunting convention and it proved to be excellent far beyond underwater use. It was shown as a perfect light for heavy rain and harsh weather, the kind you can rely on all night long. It’s extremely tough, built to handle anything you throw at it, and the bright colors are a big plus, you can always find it in the dark, even at night or in bad conditions.

A Dive Light also used out of the water
Ok let’s be honest, the lamp can be taken up to 200 meters deep, that’s not going to happened from my use. It is compact but yet easy usable with dive gloves one. Rechargeables battery allow me to quickly switch it when one is empty between dive and to recharge with USB while I swim with the fishies. Website said 5.5h of light with one battery, that’s a long dive ! Did 4.5 hours combo without before recharging it without any problem.
