The Fenix FD20 is a compact AA powered flashlight which produces a maximum output of 350 lumens and a beam throw distance of 115 meters. The FD20 features a focusing ring around the head which allows a user to manipulate the light beam from a spot to floodlight. The flashlight measures 153.2mm long with a head diameter of 25.4mm. The FD20 weighs 87 grams without any batteries installed. The flashlight is constructed from an aerospace-grade aluminum alloy which features diamond knurling for a firm grip and a Type Ⅲ hard-anodized anti-abrasive finish.
The FD20 utilizes a Cree XP-G2 S3 LED and an inner and outer dual reflector optical system. Rotating the focusing ring 360° moves the head and the reflector forward and backward from the LED alternating the focus between a spot and floodlight. The flashlight is powered by two AA (NiMH/Alkaline) batteries. Reverse polarity protection guards against incorrectly inserted cells.
