Head-to-Head Comparison Between Fenix UC35 and PD35 Flashlights
Durable Construction
Both the Fenix PD35 and UC35 are constructed with tough aircraft-grade aluminum. This ensures longevity even when exposed to harsh environments or accidental drops. To further enhance durability, each flashlight features a Type III hard-anodized anti-abrasive finish. This coating resists corrosion and wear, allowing your flashlight to maintain its sleek, tactical appearance for years.
A key design advantage of both models is the anti-roll design. This prevents the flashlight from rolling away on flat surfaces—an underrated but important feature during tactical or outdoor use.

Weight and Size
Here’s how the Fenix PD35 vs UC35 compare in terms of size and weight:
| Flashlight | Length | Diameter | Weight (without battery) |
|---|---|---|---|
| Fenix PD35 | 138mm | 25.4mm | 88g |
| Fenix UC35 | 150mm | 25.4mm | 99g |
The PD35 is slightly shorter and lighter, making it a more pocket-friendly option, while the UC35 has a longer body to accommodate its USB recharging feature. This makes the PD35 easier to carry, especially for EDC or on-the-go use.

In the comparison of Fenix PD35 vs UC35, LED technology is one area where noticeable differences begin to emerge.
- The older versions of both models came with the Cree XM-L2 (U2) LED, offering a long lifespan of up to 50,000 hours.
- However, the updated Fenix PD35 2018 Edition now features the Cree XP-L HI V3 LED, which is more powerful and offers improved beam focus and intensity without increasing power consumption.
So, while the UC35 sticks with the tried-and-true XM-L2, the PD35 pulls ahead slightly with a more modern and efficient LED system.

Maximum Lumen Output
Lumens measure brightness—and brightness is essential when you’re relying on a flashlight in dark or tactical environments.
| Flashlight | Max Lumens |
|---|---|
| Fenix PD35 | 1000 Lumens (XP-L HI V3) |
| Fenix UC35 | 960 Lumens (XM-L2 U2) |
With 1000 lumens, the PD35 has a slight edge in output. While 40 lumens may not seem like much, the newer LED in the PD35 provides a more concentrated beam and slightly better throw.
However, both flashlights are extremely bright and suitable for tactical, emergency, or everyday carry scenarios.
Beam Distance and Coverage
The brightness advantage of the PD35 translates into greater beam throw:
- PD35 Beam Distance: Up to 250 meters
- UC35 Beam Distance: Up to 200 meters
This makes the PD35 ideal for long-range visibility, while the UC35 is still a reliable performer for mid-range applications such as hiking, camping, or home security.

- Eco
- Low
- Mid
- High
- Turbo
- Strobe
These multiple modes give users the flexibility to adapt to different environments, from conserving battery during low-light indoor use to using turbo or strobe in emergency situations.
Each flashlight uses digitally regulated output to maintain consistent brightness throughout the battery life—no unexpected dimming halfway through use.
📌 Both lights also feature instant strobe access via the tactical tail switch, making them ideal for self-defense or disorienting threats.
Impact and Water Resistance
As tactical tools, both models maintain high durability standards:
- Impact Resistance: Up to 1 meter
- Waterproof Rating: IPX8 (submersible up to 2 meters for 30 minutes)
This makes them great options for all-weather use, from stormy nights to rugged outdoor adventures.

Runtime Comparison
Battery runtime plays a significant role when choosing between these two flashlights. Here’s a detailed breakdown of their maximum runtimes:
| Flashlight | Max Runtime | Eco Mode Runtime |
|---|---|---|
| PD35 | Up to 430 hours (Eco Mode) | Yes |
| UC35 | Up to 150 hours (Eco Mode) | Yes |
The Fenix PD35 clearly wins in the runtime category, lasting nearly three times longer than the UC35 on its lowest setting. This makes it a preferred choice for users who want fewer interruptions between charges or battery replacements.
📌 Runtime will vary depending on the mode used. In turbo mode, both flashlights will drain faster, but the PD35 maintains a slightly more efficient power usage overall.
Charging Capabilities: Built-In vs. External
Here’s where the UC35 takes the lead. Unlike the PD35, the UC35 includes built-in USB charging. This makes it much more convenient for users who don’t want to carry around a separate charger.
Fenix UC35 Charging Features:
- Comes with a micro-USB port built into the body
- Includes a USB charging cable
- Charges directly with any USB wall adapter, power bank, or laptop
- Battery can stay inside the flashlight during charging
Fenix PD35 Charging:
- No built-in charging port
- Requires external battery charger to recharge the 18650 battery
- Battery must be removed each time you recharge
⚡ So, if charging convenience is a priority, the UC35 is the better option.
Battery Status and Protection
Both the UC35 and PD35 come with important battery-related safety features:
- Reverse Polarity Protection: Prevents damage from incorrect battery installation
- Overheat Protection: Prevents the flashlight from getting too hot during extended use
- Low Voltage Warning: Alerts users when battery needs to be recharged or replaced
- Last Mode Memory: Remembers the last brightness setting used when turned back on
These features make both models reliable and user-friendly, especially for beginners or anyone using the flashlight in time-sensitive or mission-critical situations.

Portability & Everyday Carry (EDC)
Both flashlights are marketed as compact tactical lights, but one has a slight edge for everyday use.
| Flashlight | Length | Weight (No Battery) | Pocket-Friendly |
|---|---|---|---|
| PD35 | 138 mm | 88 grams | ✅ Yes |
| UC35 | 150 mm | 99 grams | ⚠️ Slightly bulky |
- The PD35 is noticeably shorter and lighter than the UC35, making it a better fit for pockets, EDC holsters, or tactical pouches.
- The UC35, while only 12mm longer, feels bulkier due to its built-in charging port and slightly wider mid-section.
If stealth and compactness are your top priorities (such as for law enforcement or self-defense carry), the PD35 wins here.

Real-World Usage Scenarios

Both models include:

That said, if you’re likely to use your flashlight frequently and recharge it on the go, the UC35 is more convenient thanks to the USB charging capability.

Now, let’s compare their cost-effectiveness.
| Flashlight | Average Price Range | Value for Money |
|---|---|---|
| PD35 | $65 – $75 | ✅ Excellent |

- The PD35 is generally more affordable and still delivers top-tier performance, making it an excellent value for budget-conscious buyers.

My Recommendation
The pd35 and uc35 LED flashlights are two excellent flashlight models from Fenix. They both have outstanding features and can be used for various activities. Both flashlights can be utilized for hunting, hiking, mountaineering, cycling, camping, for military personnel, or for general use. They are sturdily built and have safety features for prolonged use. The only difference they have is that the pd35 flashlight is brighter than the uc35. On the other hand, the uc35 can be recharged directly via its USB port, while the pd35 doesn’t have a USB port for recharging directly. In the battle of Fenix PD35 vs UC35, your final choice depends on whether you prioritize a built-in USB charging port (UC35) or a slightly more compact and tactical-ready design (PD35).
Moreover, both flashlights are wonderful for daily use, but the Fenix pd35 is easier to keep and handle as it is some length shorter than the uc35. I hope this Fenix PD35 VS UC35 article has given you a clear idea about their differences. However, whatever choice you make, you will get a quality light with constant brightness.
