The Nitecore DL20 underwater flashlight is the perfect light for diving, underwater sport and underwater photography. The light has a dual output consisting of a white light with a maximum output of 1000 lumens from the Cree XP-L HI V3 LED, and an auxiliary red light with a maximum output of 115 lumens. The red and white outputs can be used simultaneously, creating a softer beam that reveals the natural colour of underwater objects and helps take beautiful photos.

The torch can be powered by 1 x rechargeable Li-ion 18650, 2 x CR123 single use or RCR123 (16340) Li-ion batteries.

The DL20 is submersible to 100m with double o-rings and a deepened thread to protect the interior of the light. The torch comes with a diving lanyard for secure attachment to your gear, allowing for handsfree use whilst always ensuring the light can be quickly accessed.

The Nitecore DL20 is constructed from aero-grade aluminium alloy with a HAIII military-grade hard anodised finish which prevents seawater corrosion.
