When choosing a powerful flashlight, maximum brightness is only part of the decision. The beam must reach far enough for the intended activity, the battery system needs to support practical use, and the controls should make it easy to switch between a low-light setting and full output when necessary.
The Sofirn SP36 Pro approaches these requirements with four SST40 LEDs, an advertised maximum output of 8,000 lumens, three rechargeable 18650 batteries, USB-C charging, and the Andúril 2.0 interface. Its aluminum body and IPX8 water-resistance rating also position it as an option for camping, hiking, emergency kits, and other outdoor situations.
Unlike a compact pocket torch designed mainly for finding keys or lighting a short path, the SP36 Pro is built around higher-output illumination and configurable lighting modes. That makes it worth considering for users who need more lighting capability than a basic everyday flashlight can provide.
This review looks at the features that matter most, explains where the SP36 Pro may be useful, and highlights the limitations buyers should understand before purchasing.

The exact brightness, beam distance, and runtime achievable in practice depend on the operating mode, battery condition, thermal regulation, and environmental conditions. The product listing should also be checked for the precise battery configuration and accessories included in the selected package.
Four SST40 LEDs: What Does 8,000 Lumens Mean in Practice?
The SP36 Pro’s main selling point is its advertised maximum output of 8,000 lumens. Four SST40 LEDs provide the light source, allowing the flashlight to produce a high level of illumination when maximum output is selected.
Lumens measure the total amount of visible light emitted by a source. However, a higher lumen rating does not automatically mean a flashlight will illuminate distant objects more clearly. Beam intensity, reflector design, light distribution, and the surrounding environment also influence how useful the light appears.
For example, a wide beam can be helpful when illuminating a campsite, checking equipment, or looking across a large outdoor area. A more concentrated beam is often preferable when trying to identify objects farther away.
The SP36 Pro is marketed as a high-output flashlight for situations that require substantial illumination. Its four-emitter configuration makes it worth considering for users who regularly work or spend time outdoors after dark.
However, 8,000 lumens is a maximum-output claim, not a promise that the flashlight will maintain that brightness continuously. High-output LEDs generate heat, and thermal regulation can reduce output as the flashlight warms up. Battery charge and operating conditions also affect performance.
For this reason, buyers should consider both maximum brightness and the lower settings they can use for longer periods.
Beam Distance: Is 450 Metres Enough for Outdoor Lighting?
The Banggood listing advertises a beam distance of up to 450 metres. The manufacturer’s product information lists approximately 423 metres, so the exact quoted distance varies between listings.
Either figure should be understood as a specification under particular test conditions rather than a guarantee of clear visibility at that distance.
Actual visibility depends on atmospheric conditions, surrounding light, the size and reflectivity of the object being illuminated, and the user’s eyesight. Fog, rain, dust, and other environmental factors can substantially reduce the usefulness of a distant beam.
For camping and hiking, beam distance can help when checking a trail ahead or looking across an open area. Around a campsite, the flashlight may also be useful for inspecting equipment, locating objects, or illuminating a wider area.
For routine indoor tasks, however, maximum output may be unnecessary. Lower brightness settings can reduce glare and help conserve battery power.
The key advantage of a flashlight with adjustable output is the ability to match brightness to the task instead of using the highest setting all the time.
Andúril 2.0: More Control Over Brightness
The SP36 Pro uses Andúril 2.0, a configurable flashlight interface that offers more control than a simple on-and-off switch.
Depending on the selected mode and configuration, Andúril supports brightness adjustment, different operating modes, and additional functions. Users can tailor the flashlight’s behaviour to their preferences instead of being restricted to a small set of fixed brightness levels.
This flexibility can be useful in different situations. A low setting may be appropriate inside a tent, while a brighter setting can help illuminate a trail or inspect a distant object.
However, Andúril has a learning curve. Its button combinations and operating logic may be unfamiliar to people accustomed to basic flashlights. Users who prefer straightforward controls should take time to learn the essential operations before relying on the light during an emergency.
It is also important to understand thermal regulation. At high output, the flashlight can become hot, and its brightness may automatically decrease to control temperature. Maximum output is therefore best treated as a mode for situations that need intense light rather than a setting for uninterrupted use.
Before using the SP36 Pro for the first time, consult the manufacturer’s instructions for its controls, temperature calibration, and battery-related functions.
Three 18650 Batteries: Power for a High-Output Flashlight
The SP36 Pro uses three 18650 rechargeable lithium-ion batteries. This configuration provides the power needed for its high-output lighting system.
Rechargeable 18650 cells are widely used in flashlights and other electronic devices because they offer a practical balance of size and energy capacity. Using three cells also means that battery compatibility and charging condition deserve particular attention.
Battery performance is not determined by cell count alone. Runtime depends on the capacity and condition of the batteries, the selected brightness level, the flashlight’s efficiency, and how much output the device maintains during use.
A maximum-output setting will generally consume energy much faster than a low setting. For overnight camping or extended outdoor activities, it is sensible to use lower brightness when full output is unnecessary and carry a suitable backup light.
Buyers should confirm whether batteries are included in the Banggood package they select. They should also check the required battery type and physical compatibility rather than assuming any 18650 cell will work correctly.
Use reputable batteries that meet the manufacturer’s requirements. Never mix incompatible or damaged cells, and follow the supplied charging and battery-safety instructions.
USB-C Charging for Everyday Convenience
The built-in USB-C charging port is another practical feature of the SP36 Pro.
Instead of requiring users to remove the batteries every time they want to recharge, integrated charging provides a more convenient option for routine use. The manufacturer’s specifications also describe USB-C charging with a compatible cable.
This can be useful when preparing for a camping trip, keeping an emergency flashlight ready at home, or recharging after an evening outdoors.
Nevertheless, USB-C describes the connector, not necessarily the charging speed. Buyers should check the recommended power input and charging instructions rather than assuming the flashlight supports every fast-charging standard.
Charging time will also depend on the batteries’ remaining capacity, the power source, and the charging system.
For emergency preparedness, the most useful approach is to charge the flashlight before storing it, check its battery condition periodically, and follow the manufacturer’s recommendations for long-term storage.
Because the SP36 Pro uses rechargeable lithium-ion cells, it should be charged and stored responsibly. Avoid damaged batteries, unsuitable chargers, excessive heat, and unattended charging in unsafe conditions.
IPX8 Water Resistance and the Aluminum Body
Outdoor equipment needs to cope with more than darkness. Rain, damp ground, and accidental exposure to water can all affect a flashlight’s usefulness.
The SP36 Pro is advertised with an IPX8 water-resistance rating and an aluminum-alloy body. These features make it a potential candidate for outdoor activities where durability matters.
IPX8 indicates protection against immersion under conditions specified by the manufacturer or applicable testing arrangement. It does not mean that every flashlight with this rating can be submerged to the same depth for the same duration.
The actual limits depend on the manufacturer’s specifications. Water resistance can also be affected by damaged seals, worn components, loose parts, or an improperly closed charging-port cover.
Before exposing the flashlight to water, verify the instructions for the specific model and make sure all relevant covers and seals are correctly fitted.
The aluminum body offers a solid housing for the flashlight, but it does not make the device indestructible. Avoid unnecessary drops, inspect the body for damage, and keep the charging area clean.
These precautions are particularly important if the flashlight will be used in wet outdoor environments or stored as part of an emergency kit.
Where Does the Sofirn SP36 Pro Make the Most Sense?
The SP36 Pro’s combination of high advertised output, adjustable lighting modes, rechargeable batteries, and configurable controls makes it suitable for several potential applications.
Camping: It can provide strong illumination for setting up a campsite, checking equipment, and looking around an outdoor area after dark. Lower settings may be more comfortable for tasks close to the user.
Hiking and outdoor exploration: Its advertised beam distance may be useful for looking farther along a trail or inspecting open terrain. However, users should not rely on a flashlight alone for navigation or personal safety.
Home emergency supplies: A rechargeable high-output flashlight can be useful during power interruptions or when checking poorly lit areas around a property. Keep it charged and check its condition periodically.
Vehicle emergencies: It may help illuminate a roadside repair or allow the user to inspect an area around a parked vehicle. A dedicated warning light and other roadside safety equipment may still be necessary.
General utility work: Adjustable brightness can help with tasks ranging from close-up inspection to illuminating a larger work area. For prolonged close-range work, lower output may be preferable to avoid glare and unnecessary heat.
The SP36 Pro is less compelling if your main requirement is the smallest possible everyday-carry flashlight. Its three-battery configuration and larger light assembly are better suited to users who prioritize lighting capability over minimal size and weight.

What Are the Limitations of the SP36 Pro?
A useful product review should consider the compromises as well as the advertised benefits.
1. Maximum output does not equal sustained output
The 8,000-lumen figure describes the advertised maximum. Heat management can reduce brightness during extended high-output operation, so it should not be interpreted as continuous performance.
2. The controls require some learning
Andúril 2.0 provides flexibility, but its interface is more involved than a basic flashlight switch. Users should become familiar with its essential functions before taking the light into situations where quick operation matters.
3. The battery configuration affects portability
Three 18650 batteries support the flashlight’s power requirements, but the overall package is less compact than a small single-cell torch. Consider the size and weight if you intend to carry it for long periods.
4. Battery runtime depends on how you use it
The manufacturer’s listing advertises extended operation in Eco mode, but this should not be confused with runtime at maximum brightness. Actual performance varies with the selected output, batteries, and conditions.
5. Water resistance has limits
IPX8 is a useful advertised feature, but users should follow the manufacturer’s specific immersion limits and keep seals and covers in good condition.
Understanding these limitations makes it easier to decide whether the SP36 Pro is the right tool for your needs.
Sofirn SP36 Pro vs. a Basic Everyday Flashlight
A small everyday flashlight and a high-output model such as the SP36 Pro serve different purposes.
A compact torch is generally easier to carry in a pocket, handbag, or small emergency pouch. It may be the more convenient choice for finding items, walking to a car, or handling occasional household tasks.
The SP36 Pro places greater emphasis on output, battery capacity, and adjustable lighting behaviour. Its multiple emitters and three-cell configuration may be more attractive for camping, outdoor work, and situations where a stronger beam is useful.
Neither design is automatically better. The right choice depends on how often you need intense illumination, how much equipment you are willing to carry, and whether you value advanced controls.
If portability is your main concern, a smaller flashlight may be sufficient. If you regularly need a more powerful rechargeable light and appreciate configurable modes, the SP36 Pro deserves a closer look.
If portability matters more than maximum brightness, the Astrolux K3 EDC flashlight offers a compact alternative with a different combination of lighting features.
Final Verdict: Should You Buy the Sofirn SP36 Pro?
The Sofirn SP36 Pro is a high-output rechargeable flashlight built around four SST40 LEDs, an advertised maximum brightness of 8,000 lumens, three 18650 batteries, USB-C charging, Andúril 2.0, and an IPX8 water-resistance rating.
Its strongest appeal is the combination of substantial advertised output and flexible control. These characteristics make it worth considering for camping, hiking, emergency preparation, and other tasks where a compact household torch may not provide enough illumination.
The main trade-offs are its battery configuration, the learning curve associated with Andúril, and the fact that maximum brightness cannot be assumed to remain constant throughout extended use. Buyers should also confirm the package contents and the manufacturer’s water-resistance and battery requirements.
Our recommendation: Consider the Sofirn SP36 Pro if you want a powerful rechargeable flashlight with multiple lighting modes and USB-C charging. It is a less obvious choice if your priority is a lightweight pocket torch for occasional everyday tasks.
Before ordering, compare the current Banggood price with the manufacturer’s specifications and verify whether the selected package includes the batteries and accessories you need.
The best flashlight is not necessarily the one with the highest lumen rating. It is the one that delivers the right combination of brightness, runtime, portability, and control for the situations in which you will actually use it.
