OLIGHT O'Pen 3 EDC Pen Light — 120 Lumens, Green Beam, USB-C Rechargeable

Compact precision meets versatile lighting

The OLIGHT O'Pen 3 is designed to slip into a pocket or notebook, delivering more than a typical pen when you need light. Crafted from durable aluminum and weighing just 33.5 g, it stays unobtrusive while offering thoughtful features for daily tasks like writing, presenting, or quick signaling.

Four-in-one lighting for everyday moments

This pen light combines four outputs in one compact unit: a 120-lumen white light for clear visibility on desks or in dim rooms; a two-stage red light that preserves night vision; a green beam with power under 5 mW (class 3R) for subtle signaling or alignment; and a soft, pen-tip light to guide writing in the dark.

• White light clip provides strong, steady illumination for reading, note-taking, and multi-tasking during presentations.
• Red light mode keeps your night vision intact while maintaining discreet operation in low-light environments.
• Green beam offers a safe, low-intensity signal or alignment aid without overwhelming brightness.
• Pen-tip light gives a gentle glow right at the writing surface for accuracy in low light.

Fast charging, long-lasting performance

A hidden USB-C port allows full recharge in about an hour, with the upgraded battery delivering up to 25 hours of runtime depending on mode and use.

• Immersive convenience with USB-C charging and no extra docks to manage.
• Extended runtime supports long work sessions, travel days, or back-to-back meetings.

Designed for easy, confident use

A newly designed press-to-open pocket light and a 3-position toggle switch offer quick, intuitive mode changes. A spring-loaded clip keeps the device secure in a pocket, notebook sleeve, or bag slot for daily carry.

Built to last and write well

The O'Pen 3 uses a rugged aluminum body and a recessed grip with a meteor-shower-inspired texture for a secure, comfortable hold. It accepts smooth-writing ballpoint refills compatible with the OPEN series and includes an extra oil-based refill to suit different writing preferences.

Why it might fit your routine

Whether you’re managing presentations, taking fast notes in low light, or traveling between sites, this compact light adds practical illumination, signaling, and writing support without bulk. It’s a thoughtful companion for office desks, conference rooms, or fieldwork gear.
