Tactical lights with their multiple lighting modes have always been hamstrung by their control, usually having to resort to multiple clicks or one or two buttons to cycle modes and brightness. With the PD40R, Fenix developed a duty light whose controls are an intuitive selector ring, allowing the user to precisely dial in their desired brightness or set the flashlight into SOS and strobe.

The PD40R v3.0 steps up in run time and throw distance from the v2.0. Physically the PD40 is just a little bit larger than the PD30 at a little over 6" long. It runs of a 5000mAh 21700 lithium battery. The PD40R has a USB-C charging port allowing the battery to be charged inside the flashlight (which is fortunate because none of my LiPO chargers is large enough to fit a 21700 battery).

The PD40R has a slightly crenelated crown to assist in breaking glass and as a pressure point when used a self-defense tool. Because of its control ring, the unit lacks a tail click button and thus easily tail stands. Fenix included a removable pocket clip though the unit is a bit oversized.

In my testing, I measured 2600 lumens from a freshly recharged battery, which is close enough to its stated 3000 lumen output that I consider my reading well within a margin of error. In addition, the PD40 lasted well past Fenix's 2hr and 40min runtime in Turbo brightness; I stopped my test at 3hrs and 40min and it was still not exhausted.

The only disappointing aspect of the flashlight is its control ring. I prefer the PD40's control ring system which is much more intuitive and precise than pressing button combinations. Fenix claims the ring has a hard stop at TURBO to prevent the user from accidentally activating the SOS or strobe function. But in my testing, I too often accidentally turned the unit past TURBO into SOS. My suggestion is that Fenix add additional separation space between TURBO And the intermittent modes.

Suggestions about the SOS mode in the ring control aside, the PD40Rs exceeded expectations for "professional" performance.
