The DL20 is the second diving light from Nitecore and this version can be submerged up to 100 metres depth, which is an extra 70 metres in comparison to the DL10.
It is designed specifically for underwater use as a diving torch and photography light, offering a maximum output of 1000 lumens from the Cree XP-L HI V3 LED.
Powered by one 18650 rechargeable lithium-ion battery (recommended), two CR123A non rechargeable lithium metal batteries or two 16340 (RCR123A) lithium-ion rechargeable batteries the DL20 provides low and high white outputs, low and high red outputs and a white strobe.
The white light can be turned on simultaneously with the red light which is supplementary for deep underwater photography, providing better colour rendition as red light is scarce in a deep water environment, resulting in photos that are true to colour.
The modes are easily selected with the two push buttons on the head of the torch. Hold down the front button to turn on and off the white light and hold down the back button to turn on and off the red light. Both white and red lights can be turned on at the same time. When the light is on, single pressing the front button changes between high and low white light settings and single pressing the back button changes between high and low red light settings.
With the light on or off, press and hold both the front and back buttons to access the strobe setting. Press any button once to return to the previous status.
The body is constructed using deepened thread for all-dimensional waterproofing and features double O-ring sealing to protect against water ingress so that it can be submerged up to a depth of 100 metres.
A diving wrist lanyard is included to safely keep your torch on your wrist while diving using the adjustable toggle to tighten it, and the lanyard easily attaches to the large hole on the tail of the torch.
