SKU: FD65XPBK Category:

The Fenix FD65 Focus Flashlight is a beast of a light in fairly compact form.  Its neutral white LEDs and high-efficient TIR optical lens allow this flashlight to blast 3800 lumens of light one-quarter of a mile when focused to a tighter 10° spotlight. For a wider beam, simply twist the flashlight’s head to transition to a 90° floodlight (for greater close-in visibility). The simple operation of switching through its 5 light levels and 2 strobe modes are done by its highly functional side switches that are built into the compact 6″ long and 2″ diameter body. Waterproof/dustproof design continues the long list of attributes that make this the ultimate tool for search/rescue, security and professional applications.

Output Selection
With the light on, single click the L switch for brightness decrease, and single click the H switch for brightness increase.

Flash Mode
In any state, press and hold the L switch for 1.2 seconds to enter SOS; press and hold the H switch for 1.2 seconds to enter strobe; click one of the switches once again to turn back to general brightness level.

Spot- and Floodlight Adjustment
Rotate the focusing ring to regulate between spotlight and floodlight. Counterclockwise to gradual spotlight, clockwise to gradual floodlight. (The factory default is floodlight, and it will be a little tight for first focusing ring rotating)

Lockout Function
Lock: with the light unlocked, simultaneously press and hold the two switches for over 2 seconds.  Light will blink twice on Low and then switch off to indicate locked status.
Unlock: with the light locked, simultaneously press and hold the two switches for over 2 seconds.  The light will be unlocked and activated on last used brightness.

With the light locked, press any switch will activate 2 blinks and then switch off to indicate locked status.

Intelligent Overheat Protection
The light will accumulate a lot of heat when used on Turbo output level for extended periods. When high temperature(≥ 65℃ ) is detected or after 3-minute working on Turbo, the light will automatically step down by a few lumens to reduce temperature.

Low-voltage Warning
When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached. When this happens in Eco output mode, the flashlight blinks three times every five minutes to remind you to replace the batteries. To ensure normal use, the flashlight will not turn off automatically and will work until the batteries protection activate.

Battery Replacement
Unscrew the tail cap to insert the battery with the polarity markings in the correct direction according to the signs on the bottom with the anode side (+) towards the light head, then screw the tail cap back on.

    The focus ring is too tight. It needs updating with a battery condition LED like some of the other lights but other than that, it is a great light.
