The Fenix PD36 TAC Tactical Flashlight delivers up to 3,000 lumens and a maximum beam distance of 274 meters in a compact, durable design. Its mechanical rotary selector switches between Tactical, Duty, and Lockout modes, providing quick access to high output, strobe, or a wider range of brightness levels. Powered by an included rechargeable 21700 battery, this tactical flashlight features a dual-function tail switch, an aluminum body, and IP68-rated protection.
The Fenix PD36 TAC is a tactical flashlight designed for users who need direct control over light output and activation. Its Luminus SST70 LED produces up to 3,000 lumens with a maximum beam distance of 274 meters. The compact aluminum body is suited to duty use, emergency preparedness, outdoor activities, and situations where a dedicated tactical control layout is preferred.
A mechanical rotary selector on the tail switches between Tactical, Duty, and Lockout modes. Tactical mode simplifies operation by prioritizing high output and strobe, while Duty mode provides access to five brightness levels. The dual-function tactical tail switch supports momentary activation and constant-on operation. The included 21700 rechargeable lithium-ion battery powers the flashlight, but charging requires an external compatible charger because the PD36 TAC has no built-in charging port.
The PD36 TAC's rotary selector makes its operating configuration easy to identify by position. Tactical mode prioritizes direct access to high output and strobe, while Duty mode provides a broader selection of brightness levels for general work and everyday use. Lockout mode helps prevent accidental activation when the flashlight is stored or carried.
| Selector Mode | Available Functions |
| Tactical | High output and instant strobe |
| Duty | Eco, Low, Medium, High, Turbo, and strobe |
| Lockout | Disables the switch to help prevent accidental activation |
In Tactical or Duty mode, the tail switch supports momentary activation and constant-on operation. Holding the switch for the specified interval activates strobe. Refer to the manufacturer's instructions for the exact switching sequence.
The PD36 TAC offers different output levels according to the selected mode. Turbo delivers the maximum 3,000 lumens, while the lower brightness settings extend runtime for tasks that do not require maximum output.
| Mode | Output | Runtime | Beam Distance |
| Turbo | 3,000 lumens | Up to 1 hour 30 minutes* | 274 meters |
| High | 1,000 lumens | 3 hours 15 minutes | 160 meters |
| Medium | 350 lumens | 10 hours 10 minutes | 92 meters |
| Low | 150 lumens | 18 hours 45 minutes | 59 meters |
| Eco | 30 lumens | 43 hours 10 minutes | 25 meters |
*Turbo runtime includes periods when output is reduced by the flashlight's thermal protection. Strobe output is rated at 2,000 lumens. Actual runtime varies with temperature, battery condition, and operating conditions.
The Fenix PD36 TAC includes an ARB-L21-5000U rechargeable 21700 lithium-ion battery. Unlike the PD36R V2.0 and PD36R ACE, the PD36 TAC does not have a built-in USB charging port. Remove the battery and recharge it using a compatible external charger, following the manufacturer's battery-handling instructions.
Fenix also lists the ARB-L21-4000P as a compatible battery. The ARB-L21-6000 and ARB-L21-6000B are not compatible with this flashlight. Use only batteries approved for the PD36 TAC, and observe the manufacturer's recommendations for charging and storage.
