Fenix PD36R V2 vs. Pro vs. ACE: Which Successor Should You Buy?
The original Fenix PD36R was, for years, one of the best-selling flashlights Fenix made — a genuine fan favorite among EDC and duty users. It's since been discontinued, but not replaced by a single light. Instead, the PD36 lineup now includes three current models: the PD36R V2, the PD36R Pro, and the PD36R ACE. Here's how they actually differ, and which one is worth your money.
Quick Answer
- Choose the PD36R V2 if you want the direct, best-value successor to the original — nearly identical beam distance, the lowest price of the three, and a compact everyday-carry-friendly size.
- Choose the PD36R Pro if you want more output than the V2, a duty-ready dual tail-switch layout, and remote-switch compatibility for mounted use.
- Choose the PD36R ACE if you want the most output and the longest beam distance of the three, plus the ability to customize exactly which modes the light offers.
Fenix PD36R V2 — The Direct, Best-Value Successor
The Fenix PD36R V2 is Fenix's own description of "the update to one of Fenix's best-selling flashlights" — the closest like-for-like replacement of the original PD36R. It delivers 1,700 lumens with a genuinely impressive 396-meter (1,299-foot) beam distance, runs on a 5,000mAh battery (21700, or 18650 with the ALF-18 adapter), and charges via 18W USB-C fast charging in about 2.5 hours. It's IP68-rated with a 60-day runtime on its lowest mode and a two-way body clip for flexible carry. At $99.95, it's the most affordable of the three.
Fenix PD36R Pro — The Higher-Output, Duty-Ready Option
The Fenix PD36R Pro pushes output up to 2,800 lumens, reaching 380 meters (1,247 feet). It runs on a 5,000mAh 21700 battery for up to 42 hours on its lowest setting, and charges via USB-C. The dual tail-switch layout — a tactical switch for on/off and momentary activation, plus a smaller e-switch for cycling modes and instant strobe — is built for one-handed, glove-friendly operation, and it's compatible with the AER-05 remote pressure switch for mounted use. It's IP68-rated, submersible to 2 meters, and rated for 1.5-meter impact resistance. At $119.95, it comes bundled with a free E03R V2 keychain light. Real customer reviews consistently praise the light quality and beam strength specifically.
Fenix PD36R ACE — The Most Powerful, Most Customizable Option
The Fenix PD36R ACE tops the lineup on nearly every spec: 3,000 lumens, a 415-meter (1,362-foot) beam distance — the longest of all three — and up to 63 hours of runtime on Eco mode. What sets it apart is the hidden SET button, which lets you choose between three preset configurations: Turbo and Strobe only (built for tactical use), Eco/Medium/Turbo/Strobe (general duty use), or the full range of brightness levels (everyday carry). That means the light can be configured to match exactly how you use it, rather than forcing you to cycle through modes you don't need. It runs on the same ARB-L21-5000 V2.0 battery as the Pro, charges via a hidden USB-C port in about 3 hours, and is IP68-rated with 1.5-meter impact resistance. At $109.95, it sits between the V2 and Pro on price. Independent reviewers have taken notice — GearJunkie called it "one of the best flashlights you can buy today" after a month of testing.
The Detail Most Buyers Miss: Lumens Aren't the Whole Story
Comparing beam distance across all three tells a more interesting story than lumens alone. The ACE (415m) and V2 (396m) both out-throw the Pro (380m) despite the Pro sitting in the middle on total lumens. That's because beam distance depends on how tightly the light is focused, not just how much light it produces in total. A light tuned for flood (wider, more even coverage up close) will have a shorter rated throw than one tuned for a tight, far-reaching beam, even at a lower lumen count. If maximum reach matters more to you than total brightness, don't assume the highest lumen count automatically wins.

What About the PD36 TAC?
If you've also come across the Fenix PD36 TAC, it's easy to assume it's a fourth PD36R successor — but it isn't. The PD36 TAC is a separate model in Fenix's tactical lineup, not a replacement for the original PD36R. It delivers 3,000 lumens and an 898-foot beam in a more compact 5.5-inch body, with a tactical switch plus a mechanical toggle switch for quick mode control. If a smaller, EDC-friendly tactical light is what you're after — rather than a direct PD36R successor — it's worth a look alongside the three above.
Still Have the Original PD36R?
If your original PD36R is still working fine, there's no urgent need to replace it — Fenix's warranty support and battery compatibility (all three current models use the same 21700 battery family) mean it's still a usable light for now. But if you're due for a battery replacement or the light itself has started showing its age, any of the three successors is a straightforward upgrade path. The V2 is the closest match to what you're used to; the Pro and ACE both offer more brightness than the original ever did.
Which One Should You Buy?
Start with how you'll actually use it. If you just want the closest match to the original PD36R at the best price, the V2 is the easy choice. If you want more raw output and a duty-ready dual-switch layout with remote switch support, the Pro is built for that. And if you want the most output and the longest throw of the three — plus the flexibility to configure exactly which modes are available — the ACE's SET customization makes it the most capable option, particularly if multiple people with different preferences might use the same light.
Frequently Asked Questions
Q: What replaced the original Fenix PD36R?
A: The original PD36R has been discontinued and replaced by three current models: the PD36R V2 (direct successor), the PD36R Pro (higher output, duty-focused), and the PD36R ACE (highest output, customizable modes).
Q: What makes the PD36R ACE different from the Pro?
A: The ACE has more total output (3,000 vs. 2,800 lumens) and a longer beam distance (415m vs. 380m), plus a unique SET button that lets you customize which brightness modes the light offers. The Pro instead offers remote-switch compatibility and comes bundled with a free keychain light.
Q: Is the PD36R Pro worth the extra cost over the V2?
A: It depends on your priorities. The Pro offers significantly more total output and a duty-ready dual-switch layout with remote switch compatibility. The V2 actually has a slightly longer beam distance and costs $20 less, making it the better value pick for most everyday use.
Q: Can I still buy the original PD36R?
A: No, the original PD36R is discontinued. The V2, Pro, and ACE are the current models in this line.
Q: Is the PD36 TAC the same as the PD36R?
A: No. The PD36 TAC is a separate tactical model, not a PD36R successor. It's more compact (5.5 inches), delivers 3,000 lumens, and uses a tactical switch plus mechanical toggle switch rather than the PD36R line's switch layouts.
