A modern EDC flashlight can do much more than provide white light.

Flat multifunction flashlights now combine several useful tools into a pocket-sized body, including UV light, green lasers, auxiliary lighting, magnetic mounting, rechargeable batteries, and multiple white-light modes.

Three models that represent this category particularly well are the RichFire SFA-154 CORE, Wurkkos HD01 Pro, and Olight Arkfeld Pro.

Although they share a similar flat-body concept, they are not identical. Each emphasizes a different type of everyday use.

The SFA-154 CORE combines six selectable light functions, including dedicated red and blue auxiliary lighting. The HD01 Pro focuses heavily on UV and side-light versatility. The Arkfeld Pro uses a simpler three-source design with strong white-light output and a premium control system.

This comparison breaks down their differences without assuming that one flashlight is automatically the best choice for every user.

Specifications can change between production versions, so buyers should check the manufacturer's current product specifications before purchasing.

What Is a Multifunction EDC Flashlight?

Traditional EDC flashlights usually prioritize one job: producing useful white light in the smallest practical package.

Multifunction EDC lights take a different approach.

Instead of carrying a flashlight, UV light, laser pointer, and signal light separately, these designs combine several functions into one rechargeable device.

This can be useful for:

• General everyday illumination

• Looking inside vehicles, cabinets, and equipment

• Emergency preparation

• Outdoor and campsite tasks

• Fluorescence inspection

• Presentation and pointing applications

• Hands-free lighting on magnetic surfaces

• Red or colored auxiliary illumination

The tradeoff is that adding more functions can make the interface more complicated. The best design therefore depends on whether you prioritize maximum versatility, specialized UV capability, compactness, or simplicity.

RichFire SFA-154 CORE: The Broadest Mix of Lighting Functions

[Internal link: RichFire SFA-154 CORE product page]

The RichFire SFA-154 CORE uses a flat aluminum-alloy body with a rotary selector and central button.

Its main white LED produces up to 1,000 lumens with a beam distance of approximately 100 meters.

Where the SFA-154 differs most from a conventional EDC flashlight is the number of separate functions built into the body.

It provides:

• Main white light

• Green laser

• 395nm UV light

• COB white light

• COB red light

• COB blue light

• Red/blue alternating flash

• Lock mode

The main white light supports High, Low, and Strobe, while the laser can also operate together with the main white light.

That combination makes the SFA-154 especially relevant to buyers searching for a multifunction EDC flashlight rather than simply the highest-output pocket flashlight.

SFA-154 Charging and Battery

The SFA-154 uses a built-in 1500mAh rechargeable battery and charges through USB-C.

A four-level battery indicator displays approximately:

• 25%

• 50%

• 75%

• 100%

A low-battery warning is also built into the indicator system.

USB-C can be convenient for travelers and everyday users because the same type of charging cable may already be used for phones, power banks, and other portable electronics.

Where the SFA-154 Stands Out

Its biggest advantage is not maximum lumens.

It is the combination of main illumination + UV + laser + COB white + dedicated red and blue auxiliary lighting.

For users who want one device to perform several different lighting and signaling jobs, this configuration offers substantially more mode variety than a conventional three-source EDC light.

Wurkkos HD01 Pro: Strong UV and Side-Light Versatility

The Wurkkos HD01 Pro is another flat multifunction EDC flashlight with a closely related overall concept.

Its main white light reaches up to 1,200 lumens, giving it a slightly higher rated maximum output than the SFA-154.

It also includes:

• 365nm UV

• Green laser

• White side illumination

• RGB auxiliary lighting

• Magnetic tail

• USB-C charging

• Battery-status indicator

One important difference is its 365nm UV emitter.

For users who specifically prioritize fluorescence inspection, a 365nm UV source is generally more specialized than the 395nm UV found on many general-purpose multifunction flashlights.

That makes the HD01 Pro particularly interesting for users whose primary secondary function is UV rather than colored signaling.

Compact Flat Design

At approximately 111.5 × 27 × 17 mm and around 100 grams, the HD01 Pro is also thinner and slightly lighter than the SFA-154.

Its relatively slim dimensions make it attractive for users who want a multifunction flashlight that occupies less pocket space.

The HD01 Pro therefore has a strong position for users whose priorities are:

compactness + 365nm UV + laser + side lighting.

Olight Arkfeld Pro: A Refined Three-Source Approach

The Olight Arkfeld Pro takes a somewhat different approach.

Rather than adding a large number of auxiliary lighting modes, Olight centers the design around three major functions:

• White light

• 365nm UV

• Green laser

The white light reaches a rated maximum output of 1,300 lumens, the highest of the three models compared here.

Its UV system is rated at 365nm and up to 900mW, while a rotary selector provides quick switching between the major light sources.

The Arkfeld Pro also uses a built-in 1500mAh battery.

Instead of USB-C, however, it charges through Olight's proprietary magnetic charging system.

Magnetic Charging: Convenient but Different

Magnetic charging is convenient at a desk, nightstand, or workbench. The connector can be attached quickly without opening a charging-port cover.

However, travelers who prefer to carry one standard cable for multiple electronics may favor the USB-C systems found on the SFA-154 and HD01 Pro.

This is less a question of which system is objectively better and more a question of charging preference.

Higher Water Resistance

The Arkfeld Pro carries an IPX7 water-resistance rating, compared with IPX5 for the SFA-154 and IP65 for the HD01 Pro.

For buyers who frequently use their EDC equipment around rain, wet outdoor conditions, or work environments where stronger water protection is important, this may be a meaningful difference.

White-Light Performance: Do You Need 1,000 or 1,300 Lumens?

Maximum output numbers are easy to compare, but a difference of a few hundred lumens does not automatically determine which EDC flashlight is more useful.

The rated outputs are:

• RichFire SFA-154: 1,000 lumens

• Wurkkos HD01 Pro: 1,200 lumens

• Olight Arkfeld Pro: 1,300 lumens

For common EDC situations—walking through a dark parking area, checking under a vehicle, locating an object outdoors, or illuminating a room—1,000 lumens is already substantial output for a compact flashlight.

The Arkfeld Pro has the advantage in maximum rated brightness, while the SFA-154 trades some peak output for additional auxiliary-light functions.

If maximum white-light output is your main buying criterion, the Arkfeld Pro has the stronger specification.

If you care more about the number of different lighting tools available in one body, lumen output alone tells only part of the story.

365nm vs 395nm UV: What's the Difference?

This is one of the most important distinctions in the comparison.

Both the HD01 Pro and Arkfeld Pro use 365nm UV, while the SFA-154 uses a 395nm UV emitter.

A 365nm UV light generally produces less visible purple spill and is commonly preferred when fluorescence visibility is the primary goal.

A 395nm source produces more visible violet light. It can still reveal many fluorescent materials and can be practical for casual inspection and general-purpose EDC use.

Therefore:

Choose 365nm if UV inspection is one of your main reasons for buying the flashlight.

395nm can be sufficient if UV is one useful feature among many and your priority is a broader multifunction tool.

This distinction is more meaningful than simply asking whether a flashlight "has UV."

Auxiliary Lighting: Where the SFA-154 Changes the Comparison

The biggest functional difference appears when you move beyond the three primary light sources.

The Arkfeld Pro focuses on white + UV + green laser.

The HD01 Pro adds a side-light system with white and RGB functions.

The SFA-154 includes separate COB white, red, and blue lighting, along with a red/blue alternating flash mode.

Red light can be useful when a lower-impact auxiliary light is preferred, while the additional colored-light modes provide signaling options that are not part of the Arkfeld Pro's core design.

This makes the SFA-154 particularly relevant to users who want multiple independent lighting functions rather than only white light, UV, and laser.

USB-C vs Magnetic Charging

The charging method may seem like a small specification, but it affects daily convenience.

RichFire SFA-154

Uses standard USB-C charging.

Wurkkos HD01 Pro

Also uses USB-C charging.

Olight Arkfeld Pro

Uses Olight's magnetic MCC charger.

USB-C has the advantage of cable compatibility. If you already carry USB-C cables for other electronics, you may not need another dedicated cable.

Olight's magnetic system offers convenient snap-on charging but requires its compatible charging cable.

For home or desk use, magnetic charging can be extremely convenient. For travel and cable consolidation, USB-C may be preferable.

Size and Everyday Carry

All three flashlights use a flat profile designed to sit more comfortably in a pocket than many traditional cylindrical flashlights.

The HD01 Pro is approximately 17mm thick, making it the thinnest of the three based on their listed dimensions.

The SFA-154 is approximately 25mm thick and weighs 107 grams.

The Arkfeld Pro weighs approximately 111 grams and also uses a relatively slim flat-body design.

If minimizing pocket thickness is the priority, the HD01 Pro has the strongest specifications.

If the additional COB lighting functions matter more, the slightly larger SFA-154 may make sense despite the extra thickness.

Which Multifunction EDC Flashlight Should You Choose?

There is no universal winner because the three models emphasize different priorities.

Choose the RichFire SFA-154 CORE if:

• You want numerous lighting functions in one device

• You want a green laser and UV light

• You want dedicated COB white, red, and blue lighting

• You prefer USB-C charging

• You want a magnetic tail

• You value signaling and auxiliary-light options in addition to normal illumination

The SFA-154 is best understood as an all-in-one multifunction EDC light, rather than simply a flashlight competing on maximum lumen output.

Choose the Wurkkos HD01 Pro if:

• 365nm UV is important to you

• You want USB-C charging

• You prefer a thinner flat EDC body

• You want RGB and side-light functions

• You want slightly higher rated white-light output

The HD01 Pro offers an especially compelling combination for users interested in UV inspection and compact multifunction carry.

Choose the Olight Arkfeld Pro if:

• You prioritize maximum white-light output among these three models

• You want 365nm UV

• You prefer a simpler three-function system

• You like magnetic charging

• Stronger water resistance matters

• You prefer the Arkfeld control interface and ecosystem

The Arkfeld Pro is a strong option for buyers looking for a more streamlined white + UV + laser combination.

Final Verdict

The RichFire SFA-154 CORE, Wurkkos HD01 Pro, and Olight Arkfeld Pro all demonstrate how much functionality can now fit into a compact flat EDC flashlight.

But they solve the problem differently.

The Olight Arkfeld Pro emphasizes strong white-light performance, 365nm UV, a green laser, and a streamlined interface.

The Wurkkos HD01 Pro combines 365nm UV and laser functionality with a particularly thin body and versatile side lighting.

The RichFire SFA-154 CORE focuses on the broadest range of independently selectable lighting functions, combining its main white LED, green laser, 395nm UV, COB white, red, and blue lighting in one rechargeable platform.

For buyers comparing multifunction EDC lights, the best choice therefore depends less on a single lumen number and more on which secondary functions you will actually use.

If you mainly want premium white-light, UV, and laser functionality, the Arkfeld Pro is a logical choice.

If 365nm UV and thinness are priorities, consider the HD01 Pro.

If you want an EDC flashlight that combines conventional illumination with the widest variety of auxiliary and signaling modes in this comparison, the RichFire SFA-154 CORE deserves consideration.
