The Fenix PD45R ACE is a high-output rechargeable tactical flashlight designed for users who want precise control over how their light operates. Its Luminus SFT70 Gen2 LED produces up to 3,200 lumens and a maximum beam distance of 410 meters, making it suitable for professional use, outdoor activities, emergency preparedness, and long-range illumination.
The PD45R ACE features a mechanical selector ring with General, SET, and Lock modes. Its customizable SET system offers six configurations, allowing you to choose how many brightness levels are available. The tactical tail switch provides momentary and constant-on activation, while the included 6,000mAh rechargeable 21700 battery charges through a concealed USB Type-C port. The CNC-machined aluminum body and IP68-rated construction are designed for demanding conditions.
The PD45R ACE is designed for users who want to tailor their flashlight's controls to their preferred tasks. Its SET mode offers six configurations, each providing access to a different number of brightness levels. This lets you simplify operation by limiting the available outputs or retain a broader selection for general-purpose use.
| SET Option | Available Brightness Levels |
| Option 1 | One brightness level |
| Option 2 | Two brightness levels |
| Option 3 | Three brightness levels |
| Option 4 | Four brightness levels |
| Option 5 | Five brightness levels |
| Option 6 | All six brightness levels |
To select a SET configuration, rotate the selector ring to SET and follow the manufacturer's switch sequence. The number of flashes indicates the current option. Press the tactical tail switch the required number of times to select a new option, then return the selector to General mode to save and use the configuration.
The mechanical selector ring provides three primary operating positions:
Holding the tail switch for the specified interval activates strobe. Follow the manufacturer's instructions for mode switching, configuring SET options, and locking or unlocking the flashlight.
The PD45R ACE offers six brightness levels, from Eco for extended runtime to Turbo for maximum illumination. Its maximum beam distance of 410 meters makes it suitable for situations where reaching distant objects is important, while lower settings help conserve battery power for routine tasks.
| Brightness Level | Output |
| Eco | Low-output illumination for extended runtime |
| Low | Reduced output for close-range tasks |
| Medium | Balanced output for general use |
| High | Higher output for outdoor illumination |
| Ultrahigh | Very high output for demanding tasks |
| Turbo | 3,200 lumens |
| Strobe | Flashing mode accessed through the tail switch |
Fenix specifies a maximum runtime of up to 57 hours under its stated test conditions. Runtime varies by brightness setting, battery condition, temperature, and operating conditions. High-output operation can trigger thermal regulation, which reduces output to manage heat.
The Fenix PD45R ACE includes an ARB-L21-6000 rechargeable 21700 lithium-ion battery with a capacity of 6,000mAh. Its hidden USB Type-C charging port is exposed by loosening the flashlight's neck as directed in the manual. The charging indicator displays red while charging and green when the battery is fully charged.
Fenix recommends using an appropriate protected Fenix ARB-L21-series battery. The manufacturer specifies a typical charging time of approximately three hours with an 18W-or-higher charging adapter. After charging, tighten the neck securely to maintain the flashlight's intended dust and water protection. The flashlight cannot be operated while charging.
