The Fenix SD20 Diving Light has a maximum output of 1000 lumens from the white Cree XM-L2 U2 and can be powered by either 2 x 18650 rechargeable batteries or 4 x single use CR123A batteries. The diving light also has a red XQ-E LED giving 105 lumens of red light.

Whether you are deep-sea exploring, hunting or observing the underwater nightlife, the SD20 is built to cater for all diving activities.

The Fenix SD20 Diving Light is controlled by an innovative rotating magnetic ring for one-handed operation, offering convenience and assured illumination to divers. The magnetic control ring also has a battery level indicator setting. If the diving light detects a low voltage in will shift down in brightness to extend the remaining running time.

The flashlight has built-in overheat protection so can also be used safely out of the water. The Fenix SD20 Diving Light has a smooth reflector and a toughened ultra-clear glass lens with anti-reflective coating. The dual layer body design improves durability and corrosion resistance. The body is sealed with a double O ring system. The lanyard is adjustable & highly visible.
