Fenix SD10 Diving Light

The SD10 from Fenix utilizes motion control technology to simplify the user-interface of diving lights. A simple shake of the light is all you need for output selection. The twisty ON/OFF tail switch is locked to the body to prevent the switch being unscrewed too far and thus eliminate the risk of flooding.

Powered by one 18650 or two CR123A batteries, this 100-metre submersible torch puts out 930-lumens of neutral white light for excellent colour rendition.

Max beam distance on land is an impressive 300 metres and the SD10 features intelligent thermal control which reduces output when a high temperature is detected to prevent overheating during use out of the water.

Three lighting levels of 110 lumens (14 hrs), 385 lumens (4 hrs) and 930 lumens (1.5 hrs) can be selected either by a simple shake of the torch or via the twist operated tail cap switch.

SD10's body is constructed using a dual layer anti corrosion design and features twin O-ring sealing to protect against water ingress.
