Fenix SD20 is specially designed for diving activities, but also serves as a general purpose torch thanks to built-in overheat protection that controls the flashlights body temperature out of the water. This diving flashlight delivers integrated 1000-lumen white light and 105-lumen red light beams. The rotating magnetic ring mode selector is easy and convenient to operate with one hand. 100-metre waterproofing frees your underwater exploration with a large safety margin.
Battery Level Indicator
When rotating the magnetic ring to the battery level output, there are three states: red light constant-on displays sufficient power level, red light slow flash displays poor battery level, red light quick flash displays critical battery level.
Low-voltage Protection
1. When the light works at High output, if the detected voltage is lower than the preset voltage of 6.2V, the output will automatically downshift to 400 Lumens.
2. When the light works at High or Low output, if the detected voltage is lower than the preset voltage of 6.0V, the output will automatically downshift to 100 Lumens.
3. When the light works at the Red light mode, if the detected voltage is lower than the preset voltage of 6.0V, the output will automatically downshift to 25 Lumens.
Intelligent Over-heat Protection
The light will accumulate a lot of heat when it is working at High output. When the light is overheated internally up to 65c or above, the flashlight will automatically adjust the output to prevent the light from overheating.
