The Fenix PD36 TAC is a 5.5-inch, pocket-clip tactical light that puts out 3,000 lumens and reaches 898 feet, with a tactical tail switch, a mechanical toggle to change modes, and two operating modes so it can be a duty light or an everyday light depending on how you set it. It runs on a USB-C rechargeable 21700 with a 160-hour Eco runtime. Here is what makes it different from the PD36R and who should buy it.

TAC versus PD36R
The PD36R is Fenix's everyday 21700 light with a side switch. The PD36 TAC takes the same size and power and moves everything to the tail: a tactical switch for momentary and constant on, and a mechanical toggle that flips between two operating modes. In tactical mode you get instant turbo and strobe; in the other mode you get a normal light with a full range of levels. You choose once, with the toggle, and the tail switch does what you expect after that. The trade is that the TAC has no side switch, which is exactly what tactical users want.
The battery charges itself
The ARB-L21-5000U is a 21700 cell with the USB-C port on the battery, so it charges in or out of the light in about four hours. That also means a spare cell is a spare charger. 160 hours on Eco means the light is ready when you pick it up weeks later.
Build
A6061-T6 aluminum with double springs at both ends of the battery tube, which is the detail that keeps the light from flickering under recoil or impact. At 5.5 inches with a clip it rides in a pocket or on a belt.
Carrying it
Pocket clip for daily carry. For belt carry with the tail switch exposed for momentary from the holster, see our flashlight sheath collection.
Who should buy it
Anyone who wants a tactical interface in a light that still fits a front pocket: duty, defensive carry, or simply a preference for tail switches. If you want a side switch for everyday convenience, the PD36R or E35R fit better. If you want more throw in a bigger body, the TK20R V2.0.
