The Olight Arkfeld Pro and Olight Arkfeld Ultra represent the company's latest generation of EDC (Everyday Carry) flashlights, designed for users who need reliable illumination without sacrificing portability. Both models share a similar core design philosophy but target slightly different user needs through their performance specifications.
The Arkfeld Pro serves as Olight's balanced EDC solution, offering 1000 lumens of output with a 135-meter beam distance while maintaining a compact 2.47-ounce weight. This makes it ideal for users who prioritize portability and all-day carry comfort. The best Olight flashlights for EDC typically excel in this balance between performance and size.
The Arkfeld Ultra, positioned as the premium variant, pushes performance boundaries with 1200 lumens and a 150-meter beam distance while only adding 0.18 ounces to the weight. This makes it suitable for users who occasionally need that extra burst of light for demanding tasks while still valuing EDC practicality. Both models inherit Olight's signature features including magnetic tail switches, USB-C charging, and IPX8 water resistance.

The Arkfeld Pro and Ultra share identical construction materials that contribute to their robust feel despite their small size. Both flashlights feature a 6061-T6 aluminum alloy body with a type III hard-anodized finish, providing excellent corrosion resistance and durability. The anodizing process creates a scratch-resistant surface that maintains its appearance over time, crucial for an EDC item that lives in your pocket or bag daily.
The tactical bezel on both models serves dual purposes: it provides impact resistance while also offering a secondary grip option for emergency use. The bezels are designed with rounded edges to prevent snagging in clothing, a thoughtful detail for everyday carry. Both flashlights utilize quality o-rings throughout their construction, ensuring consistent water resistance and preventing dust ingress.
The magnetic tail cap represents one of Olight's signature innovations, serving multiple functions beyond simple on/off switching. This patented design allows the flashlight to magnetically attach to metal surfaces, providing hands-free illumination-a feature particularly useful for mechanics, hobbyists, or anyone working in tight spaces. The tail cap also incorporates a stainless steel strike bezel for emergency glass-breaking capability, adding practical utility to an already feature-rich design.
The size difference between the Pro and Ultra is subtle but noticeable when comparing them side-by-side. The Arkfeld Pro measures 2.56 inches in length, 1.18 inches in diameter, and 0.63 inches in thickness, while the Ultra is slightly larger at 2.68 inches long, 1.22 inches in diameter, and 0.67 inches thick. These dimensions place both models in the "pocketable" category, though the Pro fits more comfortably in smaller pockets.
| Specification | Olight Arkfeld Pro | Olight Arkfeld Ultra |
|---|---|---|
| Length | 2.56 in (65 mm) | 2.68 in (68 mm) |
| Diameter | 1.18 in (30 mm) | 1.22 in (31 mm) |
| Thickness | 0.63 in (16 mm) | 0.67 in (17 mm) |
| Weight (without battery) | 2.47 oz (70 g) | 2.65 oz (75 g) |
| Weight (with battery) | 3.53 oz (100 g) | 3.70 oz (105 g) |
The weight difference of just 0.18 ounces (5 grams) between models is barely noticeable in daily carry, making both options equally viable for EDC use. In real-world terms, this weight difference is less than a standard AA battery, making the choice between models more about performance preferences than practical carry considerations.
The performance gap between the Arkfeld Pro and Ultra becomes most apparent when examining their light output specifications. The Arkfeld Pro delivers 1000 lumens of maximum brightness with a 135-meter beam distance, while the Ultra pushes these numbers to 1200 lumens and 150 meters respectively. This 20% increase in both output and throw distance represents the most significant hardware difference between the two models.
Both flashlights utilize a Luminus SST70 LED, which is one of the most efficient high-output LEDs available for flashlight applications. The SST70 provides a neutral white color temperature (approximately 5700K) that offers good color rendering without being overly cool or warm. The beam profile on both models features a slightly floody throw with a hotspot in the center, making them versatile for both close-up tasks and medium-range illumination.
| Specification | Olight Arkfeld Pro | Olight Arkfeld Ultra |
|---|---|---|
| Max Brightness | 1000 lumens | 1200 lumens |
| Beam Distance | 135 m (443 ft) | 150 m (492 ft) |
| LED Type | Luminus SST70 | |
| Color Temperature | 5700K (Neutral White) | |
| Beam Type | Slightly floody throw with hotspot | |
Battery performance represents one of the few areas where the Pro actually outperforms the Ultra. Both flashlights use a single 18650 rechargeable lithium-ion battery, with the Pro rated for 50 minutes of runtime at maximum brightness, while the Ultra offers 45 minutes. This difference is minimal in real-world use but may be noticeable during extended outdoor activities.
The battery situation becomes more nuanced when considering power modes. Both models feature a sophisticated 6-mode UI that includes:
The Ultra's higher power consumption on Turbo mode (1200 vs 1000 lumens) reduces its effective runtime across all higher brightness levels. However, both flashlights offer excellent efficiency on lower modes, with the Eco mode providing an impressive 40 hours of runtime on a single charge.
| Mode | Olight Arkfeld Pro | Olight Arkfeld Ultra |
|---|---|---|
| Turbo Runtime | 50 min | 45 min |
| High (300lm) Runtime | 3h 30min | 3h |
| Mid (100lm) Runtime | 8h | 7h 30min |
| Low (30lm) Runtime | 20h | 18h |
| Eco (5lm) Runtime | 40h | 36h |
Both flashlights feature USB-C charging with a maximum charge rate of 1A, replenishing the battery in approximately 3 hours from a 5V source. The charging port is conveniently located on the tail cap, protected by a rubber cover that maintains the IPX8 water resistance rating. The battery level indicator provides a 4-level charge status display through a single LED on the tail cap, though this feature requires the flashlight to be in standby mode.
An important compatibility note: while both flashlights are designed for 18650 batteries, the Pro can also use a 16340 battery with slightly reduced performance. This flexibility can be useful in emergencies or when traveling light, though 16340 batteries typically offer lower capacity than 18650s.
Beyond their core performance specifications, both the Arkfeld Pro and Ultra incorporate several features that enhance their practical utility as EDC flashlights. One of the most innovative is the magnetic tail switch, which serves multiple functions:
Both models also feature IPX8 water resistance, rated for submersion up to 2 meters for 30 minutes. This rating makes them suitable for use in rain, snow, or even brief accidental immersion without damage. The waterproofing is achieved through quality o-rings and precision-machined components that maintain their seal under pressure.
The UI design on both flashlights represents Olight's latest interface evolution. The 6-mode system is accessed through a side switch that cycles through modes in both forward and reverse directions for intuitive operation. The modes include:
The strobe mode on both models operates at 10Hz, providing an effective disorientation/strobe effect for self-defense or emergency signaling. Both flashlights include a lockout mode that prevents accidental activation by holding the side switch for 1 second, a crucial safety feature for pocket carry.
