Olight marked its 19th anniversary recently with several new releases: the Baton 4 Pro, the Baton Ultra, and the ArkPro Ultra Onyx Black.

Baton 4 Pro & Baton Ultra

Crafted for everyday adventure, the Baton Ultra and Baton 4 Pro combine a compact, easy-to-carry design with impressive lighting performance. One delivers a max output of 1,600 lumens, and the other 1,800 lumens.

Olight said both lights deliver remarkable brightness and reach, making them reliable companions for everyday tasks and light outdoor activities such as hiking, camping, or evening walks. Thoughtfully engineered for convenience, both lights feature a dual-switch interface for intuitive control and a refined anti-slip grip.

Both also offer versatile dual charging with Olight’s magnetic charging option and a USB-C option. Powered by a 3,500 mAh battery, they provide dependable runtimes that keep up with everyday use and extended adventures, the company said.

ArkPro Ultra for Any Task

Olight said the ArkPro Ultra is for people who do it all, from backpacking to the trades, where UV can detect hidden secrets. It is powered by a 2,000 mAh battery that outlasts thousands of disposables and features four light sources:Spot

• Flood
• 365nm UV
• 3R Green Lazer

ArkPro Series: Multi‑Functional Use

Olight said the ArkPro series redefines everyday carry with multi-light versatility, iconic flat design, and refined craftsmanship. ArkPro and ArkPro Ultra allow you to switch quickly between Pure Flood, spotlight, and UV with the intuitive, precisely calibrated rotary selector.

The green laser works separately or together with any of the other three lights, creating a total of seven lighting configurations.

ArkPro Lite keeps things simple with white light, UV light, and red light for night vision.

Key Features of ArkPro & ArkPro Ultra

• Olight’s self-developed LED: The EIP 1 produces a crystal clear, pure white beam with an incredibly low DUV of < 0.006 — meaning it is free of any distracting color tint, all while achieving an industry-leading efficiency of 134 lumens per watt.
• Olight’s superalloy OAL: Made from Olight’s durable O-aluminum, the ArkPro Ultra defies scratches, resists breaking, and shrugs off dents. Your flashlight stays sharp and clean after drops, wear, or heavy outdoor use.
• The ArkBeat: At the core of the ArkPro Ultra lies its heart: a glowing symbol that briefly pulses when the light is activated, changing color based on how long you've used the flashlight. It symbolizes a growing connection between you and your gear.

Low‑Impact Lighting

Olight said much of the industry focuses on higher lumens, but real-world use rarely requires maximum brightness. The ArkPro Series was designed from the start to deliver just-enough, precisely controlled light. No blinding brightness, no wasted light.

Designed to Last, Packaged to Protect

Since August 2025, the ArkPro Series has used plastic-free, paper-based packaging, sourced from FSC-certified sustainable forests.

The new Baton Series follows the same standard. But Olight said sustainability isn't just about what you throw away; it's about what you keep.

That's why Baton Ultra and ArkPro Ultra are built with Olight's proprietary O‑Aluminum unibody, which is nearly twice as strong as standard 6061 aluminum, and they come with a lifetime warranty in the US, Germany, France, Japan, and Australia.
