The SD20 is a versatile diving lamp from Fenix. With both red and white light you will get along well in both clear and cloudy water. Via the magnetic rotary switch, you can easily operate the 3 light levels with one hand or choose to display the battery voltage. The 2 18650 Li-ion batteries or the 4 CR123As provide sufficient capacity to illuminate your dive for 3-7 consecutive hours, depending on the chosen position.

The insulated body ensures a longer burning time at low water temperature and protects against corrosion. Because of the extra large wrist loop hole, it is easy to attach a thicker wrist loop or other string. The sturdy design and the double O-rings ensure that the lamp can be used on all underwater adventures up to a depth of 100 meters.
