What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Before buying a 4-in-1 EDC flashlight, check what the four functions actually are, whether its beam and useful runtimes suit your tasks, how it is powered, and whether its size, controls and durability claims fit everyday carry. “4-in-1” is not a standard feature bundle: it can describe a pocket light with UV and RGB modes, a flashlight with a laser and emergency signals, or a much larger work light.
1. Confirm what the four functions are
Read the mode list for the exact model and version rather than relying on “4-in-1” in the product name. Decide which functions you would use and whether they are genuine separate capabilities or variations on one kind of light.

- IMALENT GR35: a white beam, a red or green laser depending on version, 365nm UV, and red/blue emergency signals. IMALENT also describes different versions and kits, so check the selected SKU. These are manufacturer descriptions, not independent test results.
- Lumintop Black Cat: warm-white, UV and RGB modes in a keychain light. Its advertised 400 lumens are a manufacturer figure.
- WORX WX027L: flashlight, 360-degree lantern, desk lamp and emergency strobe. It is an area/work light, not a pocket-sized equivalent to a keychain torch.
For any model with a laser, confirm the exact version and its laser classification in the documentation for the item you are buying, and check the current rules that apply where you live. The GR35 product information cited here does not specify a classification.

Think first about where the light needs to go. A broad flood is useful for nearby repairs, reading or lighting a room; a more focused beam helps you see farther along a path. Look for beam distance and output in the modes you expect to use, not just the headline maximum. A peak-output figure alone does not tell you how long that brightness lasts or what the light sustains during ordinary use.

Manufacturers do not necessarily measure or present their figures under identical conditions, so treat figures from different brands as product-specific rather than as a controlled comparison.
| Example | Published light figures | What the figures help you assess |
|---|---|---|
| IMALENT GR35 | IMALENT lists 2,800 lumens and 426m reach. | Whether the stated output and reach fit your distance-lighting needs; check the mode and runtime details for your intended use. |
| WORX WX027L | WORX lists 130 lumens for flashlight mode and 480 lumens for lantern mode. | The difference between a directional flashlight and a broad area-light function. |
| NITECORE EDC09 | NITECORE’s manual lists mode-specific figures. | A reminder to read the mode-by-mode data and its stated test conditions, rather than comparing only the biggest number. |
3. Check the battery, charging and runtime together
Look for the battery type and capacity, whether it is built in or replaceable, how easy it is to obtain a compatible replacement, and the runtime at the brightness levels you will actually use. Check the charging connector or system and how the light indicates remaining charge. If charging accessories are part of the setup, count their size and weight as part of what you carry.

- IMALENT describes a 7,000mAh magnetic charging case that also works as a power bank. Check whether that case comes with your chosen package and whether its added bulk makes sense for your routine.
- NITECORE lists the EDC09’s built-in 1,100mAh Li-ion battery, USB-C charging and power indicators; its PDF also lists an included USB-C cable and diffuser. The PDF gives an approximate charge time of 1 hour 20 minutes using a 5V/2A adapter. Its listed runtime and performance data were measured using the built-in battery under ANSI/PLATO FL 1-2019, at 26°C in NITECORE’s lab; the manual cautions that real-world results may vary with environmental conditions. It lists up to 250 hours in the lowest mode, so check that mode’s output before treating the runtime as useful for your needs.
- SOFIRN describes the SR15 as using one 21700 cell, charging through USB Type-C at 5V/3A, and providing a power-bank function. Its page lists 4,500 lumens, a 510m beam and 128g without the battery; these are manufacturer-published figures.
A stated battery capacity does not establish how many times a light can charge a phone. Usable energy, conversion losses and the phone’s battery all affect that result; the GR35 page does not quantify phone-charge count.
4. Decide whether it is really practical to carry
Check dimensions and weight for the complete setup, not only the bare light. Consider whether the body fits your pocket, snags on fabric, rolls on a work surface, or is comfortable to retrieve quickly. A clip, magnet, charging case or extra battery may improve utility but also changes what you carry.
Rank #3
- [4 Powerful Light Sources for Versatile Use] This flashlight features four light sources: a 1300-lumen main white light, a green laser (<5mW), UV light (<2100mW), and a 1300-lumen side warm light. The side warm light also can switch to red warning light strobe for emergency signaling.(Black)
- [Multiple Brightness Modes for All Conditions] The white and warm lights come with three brightness levels (low, medium, high) and a strobe mode. The side warm light strobe mode, making it ideal for emergency situations.(Black)
- [Easy Operation with Simple Controls] Equipped with just two buttons, one for switching between light sources and another for toggling between white and warm light modes. The intuitive design makes it easy to use, even in the dark.(Black)
- [Long Battery Life and Fast Charging] Powered by a 1200mAh large capacity battery, this flashlight offers long-lasting performance. It features a Type-C charging port for quick and convenient recharging and includes a battery percentage display for real-time monitoring. The product uses a prismatic lithium-ion polymer pouch battery, model HC102060, which has passed UN38.3 testing, is supported by an MSDS, and complies with applicable safety standards. (Black)
- [Magnetic Base for Hands-Free Use] The flashlight is equipped with strong magnets on both the front and the bottom, allowing it to attach to metal surfaces. This hands-free feature is perfect for tasks that require both hands, such as repairs or emergency work.(Black)
The size difference between product types can be substantial: Lumintop advertises the Black Cat at 22g, while WORX lists 0.78kg machine weight for the WX027L, which has a telescoping shaft and pivoting head. The first is a keychain-light example; the second is designed as a larger work/area light. Those weights and designs are not like-for-like EDC choices.
5. Read the durability claims and carrying safeguards
Check the precise ingress-protection and impact claims for the selected model. Do not treat a general word such as “waterproof” as a promise about every kind of water exposure or use; rely on the manufacturer’s exact rating and explanation.

- IMALENT lists IPX7 for the GR35 on its product page.
- Lumintop lists IPX4 for the Black Cat on its product page.
- NITECORE lists IPX6 and 2m impact resistance for the EDC09 in its manual.
Find out whether the controls can be locked or otherwise protected from accidental activation in a pocket or bag. SOFIRN advises loosening the tailcap or using lockout if available to prevent accidental activation during carry. NITECORE says the EDC09’s ATR module regulates output according to working conditions and ambient environment; read the manual for the behavior of the particular light you are considering.

Work out how you reach the mode you need and whether doing so requires cycling through modes you would rather avoid. If possible, try the interface with the hand you plan to use and with gloves. For reference, NITECORE documents a slide switch and M button for the EDC09, while WORX says the WX027L’s functions are selected with a button. Those descriptions alone do not establish which light is easier to use.
