Category: Comparisons
Compare the Fenix PD36 TAC and PD35R ACE tactical flashlights. Key differences in mode control, battery type, and intended use help you decide between a dedicated duty light and a versatile EDC.
Quick Answer
For dedicated tactical or duty use with instant access to strobe and max output, choose the Fenix PD36 TAC. For a more versatile everyday carry (EDC) with a broader mode range and smaller battery, the Fenix PD35R ACE is the better fit.
Mode Control: Dedicated Tactical vs Versatile Duty
The PD36 TAC features a rotary toggle switch on the tail that lets you instantly switch between Tactical Mode (limiting output to strobe and max brightness) and Duty Mode (accessing all brightness levels). This is ideal for users who need a predictable, no-fuss response in high-stress situations.
The PD35R ACE uses a side switch to cycle through all modes. While it offers more flexibility for everyday tasks, it may require a moment of attention to select the desired mode, which could be a drawback in a fast-paced tactical scenario.
Battery and Runtime
The PD36 TAC is powered by a 21700 battery, providing longer runtime and higher capacity compared to the PD35R ACE's 18650 battery. This makes the PD36 TAC better suited for extended duty shifts or prolonged use without recharging.
The PD35R ACE uses a more common 18650 battery, which is widely available and compatible with many other flashlights. It also includes a USB Type-C charging port for convenient recharging, similar to the PD36 TAC.
