Illuminate the beauty of the aquatic world at depths as great as 328' with the Fenix SD11 LED Diving Flashlight, which features white and red modes. With a wide 110° beam angle, it works for general underwater illumination or photo/video lighting.

The SD11 outputs white light at brightness levels of 500 and 1000 lumens. It can also emit a combination of white and red light at 250 lumens in R+ mode, which will offer better color correction to make subjects look more natural and vibrant. Powered by a single 18650 lithium-ion battery or a pair of CR123A lithium cells, the SD11 will run for 2 - 3.7 hours, depending on the output level selected.

Built for durability, the SD11 is constructed from an aluminum alloy that has been anodized for extreme resistance to corrosion. The body has a knurled design that helps prevent it from slipping out of wet hands, and it is also shock-resistant against drops up to 3.28' as a second line of defense.

Light Performance
  • CREE XM-L2 U2 neutral white and CREE XQE red LEDs
  • Output levels of 1000 and 500 lumens in white light mode
  • R+ mode combines white and red light and features a 250-lumen output
  • Blend of white and red LEDs creates a warmer color temperature, which helps to restore hues that are absorbed underwater so your subjects look more natural and vibrant
  • Digital output regulation maintains constant brightness
  • If light heats up to a temperature of 65°C or higher at the maximum output, it will automatically reduce the brightness to 700 lumens to prevent overheating. Once it cools down, it will increase the output again
  • Run time of 2 - 3.7 hours with a single 18650 lithium-ion battery or a pair of CR123A lithium cells, depending on the brightness level selected
  • Battery indicator keeps you apprised of the power level
  • Reverse polarity protection prevents damage if batteries are inserted incorrectly
Switching Mechanism
  • Magnetic rotating ring allows you to power the light on/off, cycle through output settings, and check the battery level - all with one hand
Construction Details
  • Dual-layer body structure for durability
  • Made from an aluminum alloy with a type III hard-anodized finish for extreme resistance to corrosion
  • Knurled design helps prevent the light from slipping out of wet hands
  • Shock-resistant against drops up to 3.28'
  • Tail cap with large buckle enables quick and easy extraction from a pocket or case, and serves as a convenient point of attachment to a strap or clip
  • Supplied flashlight clip and camera mount enable connection to most action cameras and DSLRs
