Description
The Olight O’Pen 3 is a powerful 4-in-1 multifunctional pen light designed for professionals, everyday carry, and emergency use. Housed in a slim A6061-T6 aluminum body, it seamlessly combines a white LED flashlight, red light modes, pen-tip LED, and a precision green laser pointer—all in a single, pocket-ready tool.
The pen clip integrates a 120-lumen white light for task illumination, along with a two-stage red light to preserve night vision and an SOS red mode for emergencies. A discreet pen-tip LED provides soft illumination for writing in low-light environments, while the Class 3R green laser offers two brightness levels for presentations and pointing tasks.
With USB-C charging, the built-in lithium polymer battery fully recharges in about one hour without compromising the pen’s clean, streamlined design. Its tapered profile and meteor-shower grip pattern deliver excellent balance and comfort, making the O’Pen 3 a versatile everyday tool for the office, job site, outdoors, or gifting.
