Olight Anniversary Releases: Baton 4 Pro, Baton Ultra, and Arkfeld Ultra Onyx Black Compared

Introduction

Olight is marking its 19th anniversary with a sale and a handful of new flashlights, and three of them stand out as genuinely interesting for everyday carry. Two are new Baton models: the Baton 4 Pro and the Baton Ultra, which are nearly identical twins separated by a few key specs. The third is the Arkfeld Ultra in a new Onyx Black finish, which swaps in the same new LED found in the Baton Ultra while keeping everything that made the original compelling.

Baton 4 Pro and Baton Ultra: What They Share

These two lights are so close in design that it makes sense to cover them together. Both offer five brightness levels plus strobe, and below their differing maximum outputs they behave identically: high is 600 lumens, medium is 120 lumens, low is 15, and moonlight is just 1 lumen. Both use the signature Olight side switch, slightly recessed with a satisfying but not overly clicky feel, and both have a tail switch with instant access to turbo plus momentary on if you press and hold briefly.

The Baton Ultra is the more powerful of the pair, with a maximum output of 1,800 lumens, a 300-meter throw, and a maximum intensity of 22,500 candela. The Baton 4 Pro tops out at 1,600 lumens, 200 meters of throw, and 10,000 candela. The reason for that gap is the LED: the Baton Ultra uses Olight’s first self-developed LED, called the EIP1. Early impressions are very positive, with an intense hot spot, nice spill, and almost zero green tint. It is a noticeably cleaner-looking beam than the standard LED in the Baton 4 Pro.

One more difference worth noting: the Baton 4 Pro is built from 6061 aluminum, while the Baton Ultra uses OAL, Olight’s scratch-resistant super aluminum, and carries a slightly higher 2-meter impact resistance versus 1.5 meters on the 4 Pro.

Charging, Clip, and Durability

Both Batons adopt a new hidden USB-C charging port at the bottom of the tail. Give the tail a twist and the port is revealed, which keeps dirt, dust, and mud out of the connector. You can still charge magnetically through the tail, and a slot charger works too if you already own one. The included battery is the same in both: a 3,500 mAh 3.6V 18650.

The newly designed tail is completely flat, so both lights can tail stand, and the texturing around it gives your thumb a secure grip on the switch. Both lights carry a two-way deep carry pocket clip and are IPX8 waterproof, meaning they are submersible in up to 6 feet of water, though dustproofing was not tested.

Beam Test: How They Differ Outdoors

Taken outside, the characters of these two lights become obvious. The Baton 4 Pro produces a wider hot spot and a very smooth transition out to the beam perimeter. It leans floody, which suits close-range tasks and general walking around. The Baton Ultra, thanks to the EIP1 LED, shows a tighter and noticeably more intense hot spot with a similar beam perimeter overall. Objects inside that hot spot simply look clearer, and the extra throw and candela reach further downrange.

Both lights produce a cool white color temperature, and turbo on either one lights up a large area at night. If you value a tighter, longer-reaching beam, the Ultra is the clear pick; if you prefer a floody, even wash of light, the Baton 4 Pro fits better.

Arkfeld Ultra in Onyx Black

The Arkfeld Ultra is not a new flashlight, but this version is different in two meaningful ways. First, it is part of the Ultra series and made from OAL, Olight’s super aluminum, but now in a sleek onyx black with a new surface treatment that gives it a smooth satin sheen. OAL models usually arrive in the standard grey finish, so seeing that material in black is a welcome change, and it looks gorgeous in person.

Second, it now carries the same EIP1 LED as the Baton Ultra. The rest of the formula is unchanged: 1,700 lumens, a 205-meter throw, a 1,200 mW UV light, and a class 3R green laser with two levels, all selected through the mechanical dial with spot, flood, and UV positions. The green laser easily reaches distant objects, and the flood-to-spot switching remains the reason this light is such a versatile everyday carry.

One charming detail carried over: the small glowing indicator light on the side changes color over time based on how long you have used the flashlight, with an included insert explaining what each color represents.

Overall Buying Advice

All three lights land on the same battery and the same hidden USB-C charging approach, so the decision comes down to beam preference and format. If you want a compact thrower with Olight’s cleanest beam to date, the Baton Ultra with the EIP1 LED is the standout. If you prefer a slightly more affordable, floody companion light, the Baton 4 Pro is the practical choice. And if your ideal EDC light can shift between flood, spot, and UV with a twist of a dial, the Arkfeld Ultra in Onyx Black is the most stylish and complete version of that idea yet.

Conclusion

Olight’s anniversary releases are refreshingly focused rather than scattered. Two Batons refine a proven pocket flashlight formula, and the onyx black Arkfeld Ultra gives a fan favorite a premium new look along with a genuinely improved LED. Any of the three is easy to recommend depending on whether throw, flood, or versatility matters most to you.
