The Fenix SD11 is designed primarily as a diving torch and photography light, offering a maximum output of 1000 lumens, and thanks to the built-in overheat protection it can also be used out of the water.
Powered by two CR123A non rechargeable lithium metal batteries or one 18650 rechargeable lithium-ion battery (recommended), this 100 metre submersible torch provides low and high white outputs and a R+ light output.
The R+ output is a combination of neutral white light and red light which is supplementary for deep underwater photography, providing better colour rendition as red light is scarce in a deep water environment. It is also useful for photography on land.
To aid underwater and on land photography, the SD11 comes supplied with a mount that clamps to the body of the torch and features an adaptor one side that is compatible with the waterproof casing of sports cameras such as a GoPro and the other side has an adaptor that can be mounted directly onto a tripod or inserted into the hot shoe of a camera.
The modes are easily selected by twisting the magnetic selector ring to the desired output. You can also select the battery level indicator with the magnetic ring which will display a constant red light for sufficient power, a slow flashing red light for low power and a quick flashing red light for critical power. From left to right the modes are battery indicator, R+, off, low and high.
Maximum beam distance on land is only 45 metres as the SD11 features a super wide 110° angle beam for soft and uniform lighting, which is perfect for illuminating a photography subject.
The SD11's body is constructed using a dual layer anti corrosion design and features twin O-ring sealing to protect against water ingress.
A diving wrist lanyard is included to safely keep your torch on your wrsit while diving using the adjustable toggle and easily attaches to the large lanyard hole on the tail of the torch
1. When the light works at high and low output, if the detected voltage is lower than the preset level, the output will automatically step down to prolong run-time.
2. When the light works at the R+ light mode, if the detected voltage is lower than the preset level, the red light will go out and the white light will automatically step down to remind you the battery needs replacing.
Double layer body structure protects against corrosion
Intelligent overheat protection to avoid high surface temperature
Battery level indicator to display remaining power
Rotating magnetic ring for one handed selection
Enlarged lanyard hole for quick attachment
Digitally regulated output maintains constant brightness
Low: 500 lumens; 3 hours, 40 minutes run-time; 30 m beam range
High: 1000 lumens; 2 hours run-time; 45 m beam range
R+: 250 lumens; 3 hours run-time; 23 m beam range
Tested to ANSI/PLATO FL1 standard using a Fenix 3500 mAh ARB-L18-3500 18650 lithium-ion battery.
Note: The intelligent overheat protection will automatically lower the output if the internal temperature of the torch reaches 65°C or above, in order to protect the LED from overheating. The output will gradually increase as the torch cools.
