Fenix SD10

The Fenix SD10 Diving flashlight has a maximum brightness of 930 lumens from the Cree XM-L2 T6 and is powered by one 18650 or two CR123A batteries.

The diving torch employs movement control technology to simplify the user-interface of the SD10 providing a simple shake of the light to change the output selection. The twist action on/off tail-cap switch is secured to the body to prevent the switch being unfastened too far and thus reduce the risk of flooding.

On land, the maximum beam distance is an extraordinary 300 metres. The SD10 highlights intelligent thermal control which reduces output when a high temperature is detected, inhibiting overheating during use out of the water.
