For a compact flashlight with substantial published output, the Fenix PD36R PRO is the clearest high-output option in the available specifications: Fenix rates it at up to 2,800 lumens and a maximum beam distance of 380 meters. Those are manufacturer figures, not independent comparative test results, and Turbo output can step down as the light heats up. For a much smaller pocket light, the Streamlight MicroStream USB is only 3.87 inches long and weighs 1.2 ounces, but its high mode is rated at 250 lumens.
Compact flashlight comparison
These two lights serve different priorities, rather than representing equivalent performance tiers. The PD36R PRO is the documented high-output example; the MicroStream USB favors pocketable size. Specifications below are from the manufacturers.
| Model | Published output | Published beam distance | Dimensions and weight | Power and runtime |
|---|---|---|---|---|
| Fenix PD36R PRO | Up to 2,800 lumens | Up to 380 m | 5.74 in long; 5.96 oz including battery | 5,000 mAh 21700 rechargeable battery; USB-C charging. Turbo runtime includes time at reduced output as the light heats up, according to Fenix. |
| Streamlight MicroStream USB | 250 lumens high; 50 lumens low | 68 m high; 31 m low | 3.87 in long; 1.2 oz | Rechargeable lithium-ion battery built into the light. Manufacturer-listed runtime: 1.5 hours on high and 3.5 hours on low. |
What matters beyond peak lumens
Beam distance and usable light
Lumens describe light output; beam distance describes how far the beam reaches under the manufacturer’s stated conditions. A high maximum-lumen figure alone does not tell you how much light the flashlight sustains, how broadly it illuminates a nearby work area, or how well it suits a particular task. Match the beam to the job: a more focused beam can help when looking farther ahead, while close, sustained work may be better served by a practical lower mode.
Runtime at the mode you will use
Compare runtime mode by mode, not as a single headline number. The MicroStream USB’s published figures distinguish high from low. For the PD36R PRO, Fenix notes that Turbo output steps down as temperature rises and that the stated Turbo runtime includes operation at reduced levels. That qualification matters if you need prolonged bright output rather than a short peak.

Size, weight and carry
The MicroStream USB is 1.87 inches shorter and 4.76 ounces lighter than the PD36R PRO, based on the manufacturers’ listed dimensions and weights. That makes it the more pocket-oriented comparison here; the larger PD36R PRO accommodates a higher-capacity battery and a substantially higher published maximum output. Consider whether the extra bulk is worthwhile for your usual tasks, and check the full dimensions and weight with battery before choosing a carry method.
Charging and battery compatibility
Fenix lists a 5,000 mAh 21700 battery and USB-C charging for the PD36R PRO. Streamlight lists a rechargeable lithium-ion battery built into the MicroStream USB. If replaceable batteries or spare-battery planning matter to you, verify the exact model’s documentation rather than assuming a battery can be swapped or shared across a product family.

Which one suits your work?
Choose the Fenix PD36R PRO when output is the priority
Its published 2,800-lumen maximum and 380-meter beam distance make the PD36R PRO the high-output choice among these two documented examples. It is also the longer, heavier light. Treat the headline output as a peak specification rather than a guarantee of sustained Turbo brightness; Fenix explains the thermal step-down on its specifications and FAQ page.
Choose the Streamlight MicroStream USB when pocket size leads
At 3.87 inches and 1.2 ounces, the MicroStream USB is the compact comparison for everyday carry. Its published 250-lumen high mode is far below the PD36R PRO’s maximum, so it is not a like-for-like high-output alternative. Its manufacturer page also lists water resistance; check the product specifications for the exact rating and conditions before relying on it in wet work.

Check the exact model and its controls before buying
Names within a flashlight family can conceal meaningful specification differences. Fenix lists multiple PD36 models with different maximum output figures, so compare the exact model rather than applying one PD36 specification to the whole range. Fenix’s PD36 model comparison is useful for distinguishing variants.
Compatibility is model-specific, too. Fenix lists the AER-05 remote switch as compatible with the PD36R PRO, while explicitly stating that the ARB-L21-6000 and ARB-L21-6000B batteries are not compatible. Confirm battery, accessory, charging, water-resistance, impact, and control details on the exact model’s official product information. A published durability rating is not a substitute for matching the light to the conditions in which it will be used.

- Compare length, head diameter, and weight with the battery installed against your preferred pocket, belt, or tool-bag carry.
- Check beam distance as well as lumens, and consider whether your work is mainly close-range or distance-oriented.
- Read runtime figures for the modes you expect to use, including any stated thermal reduction.
- Verify battery type, capacity, charging port, replaceability, and model-specific compatibility.
- Check the manufacturer’s water-resistance and impact specifications, switch arrangement, and any lockout instructions before use.
