Before buying a 4-in-1 EDC flashlight, verify what its four functions actually are, whether its beam and runtime suit your tasks, how it is powered and charged, and whether its size, controls and durability claims fit everyday carry. “4-in-1” is not a standard feature bundle: it can describe anything from a pocket light with UV and RGB modes to a larger work light with a lantern and desk-lamp function.
1. Confirm what the four functions are
Read the exact model and version description rather than relying on “4-in-1” in a product name. Manufacturers use the phrase for different combinations, and some modes may be useful only for specific tasks.
| Example | Functions or modes the manufacturer describes | Useful distinction |
|---|---|---|
| IMALENT GR35 | White beam, red or green laser depending on version, 365 nm UV light, and red/blue emergency signals | The product page describes separate versions and kits. Confirm the exact SKU and package contents. The figures and functions are manufacturer claims, not independent test results. IMALENT GR35 product page |
| Lumintop Black Cat | Warm-white light, UV and RGB modes | A keychain-style light aimed at minimal carry; Lumintop advertises 400 lumens, 22 g and IPX4. Lumintop Black Cat product page |
| WORX WX027L | Flashlight, 360-degree lantern, desk lamp and emergency strobe | A larger work/area light, not a keychain-sized EDC. WORX Canada lists 130 lumens in flashlight mode, 480 lumens in lantern mode and a machine weight of 0.78 kg. WORX WX027L product page |
Make a short list of the functions you would genuinely use—such as close-up work, finding something in a dark room, signaling, or UV inspection. If two of the advertised functions would rarely leave the menu, a simpler light may be a better fit.
2. Match the beam and brightness to your tasks
For nearby tasks such as reading, working on equipment or lighting a tent, look for a broad flood or area-light mode. For seeing farther down a path, check beam distance and whether the light has a more focused beam. Lumens describe light output; they do not by themselves tell you how far the beam reaches or how well it illuminates a particular area.

- Check the mode you will use: Compare output and runtime for low and medium settings as well as maximum. A peak-brightness figure does not establish how long that level lasts.
- Look for separate beam figures: A product may publish different output for its flashlight and lantern modes. For example, WORX lists 130 lumens for the WX027L flashlight and 480 lumens for its lantern; those figures describe different functions, not directly interchangeable performance.
- Read the test conditions: NITECORE’s EDC09 manual reports mode-specific figures measured with its built-in 1100 mAh Li-ion battery at 26°C in NITECORE’s lab under ANSI/PLATO FL 1-2019. It warns that real-world results can vary with environmental conditions. These are manufacturer-reported results, not an independent comparison across brands. NITECORE EDC09 manual
As examples of manufacturer-published specifications, IMALENT lists 2800 lumens and 426 m reach for the GR35, while the WORX figures above distinguish flashlight and lantern modes. Do not treat those numbers as directly comparable measurements from one shared test.
3. Check the battery, runtime and charging setup
Find out whether the battery is built in or replaceable, what type and capacity it is, and whether a compatible replacement is available where you live. Then check runtime at the brightness levels you expect to use, the charging method, and how the light indicates remaining charge.

- Built-in battery: NITECORE lists a built-in 1100 mAh Li-ion battery and USB-C charging for the EDC09, with power indicators and a USB-C cable and diffuser included. Its manual gives an approximate charging time of 1 hour 20 minutes using a 5 V/2 A adapter. The manual reports up to 250 hours in its lowest listed mode; runtime and charging figures are manufacturer-published, and the manual’s test conditions and real-world-variation caveat apply.
- External cell: SOFIRN describes the SR15 as using one 21700 cell, charging via USB Type-C at 5 V/3 A, and supporting a power-bank function. The product page lists 4500 lumens, a 510 m beam and 128 g weight without the battery; these are manufacturer specifications. SOFIRN SR15 product page
- Charging case: IMALENT describes a 7000 mAh magnetic charging case for the GR35 that also works as a power bank. Include the case in your carry-size and weight assessment, and do not infer a specific number of phone charges from its capacity: the GR35 page does not quantify that.
Check whether a stated runtime applies to a particular mode, whether a battery is included, and which cable or adapter is required. Capacity alone does not establish how long the light will run at a chosen brightness.
4. Decide whether it is genuinely pocketable
“EDC” can mean a pocket light, keychain light or a tool carried in a bag or vehicle. Check dimensions and weight with the battery and any case or clip fitted, then consider whether the shape will snag, roll, or sit comfortably in your pocket.

- [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)
- A 22 g keychain light such as the Black Cat is a different carry proposition from the 0.78 kg WORX WX027L.
- For flat or wedge-shaped lights, consider whether the clip and controls work in the pocket orientation you prefer. For round-bodied or larger lights, check whether they roll or need a dedicated spot in a bag.
- If the light has a magnetic base, stand or telescoping shaft, decide whether those features help with your real tasks enough to justify their size.
5. Verify durability, carry safety and laser details
Check the exact ingress-protection and impact claims for the model rather than treating “waterproof” as a universal promise. The cited manufacturers list IPX7 for the IMALENT GR35, IPX4 for the Lumintop Black Cat and IPX6 plus 2 m impact resistance for the NITECORE EDC09. Ratings and impact claims are manufacturer specifications; understand what the stated rating covers before exposing a light to water or drops.
Review the manual for accidental-activation protection and heat management. SOFIRN advises loosening the tailcap or using lockout if available to prevent accidental activation while carrying its light. NITECORE says the EDC09’s ATR module regulates output according to operating conditions and ambient environment. Consult the documentation for the exact light you plan to buy; control behavior and protection can differ by model.

If a model includes a laser, verify the exact version, its classification in the product documentation and the rules that apply where you live. The GR35 page describes red- and green-laser versions, but the cited product information does not state a laser classification.

Work out how you reach the modes you need. Check whether the main white light can be activated directly or whether you must cycle through other functions, and whether the switches are practical with gloves or in low light. NITECORE documents a slide switch and M button on the EDC09; WORX says the WX027L functions are selected with a button. Those descriptions alone do not establish which control layout is easier.
