Four Tools Hidden Inside One Aluminum Pen Light

The pen light category hasn’t exactly been a hotbed of innovation. Most options are cheap plastic tubes that live in a doctor’s coat pocket and do exactly one thing. Olight looked at that space and decided a pen light should actually be a pen, a flashlight, a laser pointer, and an emergency signal all at once. The O’Pen 3 is their attempt to make that work without turning the thing into a gadget that’s too busy to use.

At 6.1 inches long and half an inch in diameter, the O’Pen 3 doesn’t look like it’s hiding anything. It writes, it clips to a pocket, and it could pass for a nice aluminum pen at a meeting without anyone asking questions. The four-tool pitch only becomes obvious when you start clicking through the modes built into the clip and the body.

120 lumens from a pen clip

The white light sits in the clip itself, which is a clever placement that keeps the beam angled when the pen is clipped to a pocket or notebook. It tops out at 120 lumens, which isn’t going to replace a dedicated flashlight but handles close-range tasks like reading a menu in a dim restaurant or finding a keyhole at night without any trouble.

Where things get more interesting is the red light system. Olight built in a two-stage red mode designed for night vision preservation, the kind of feature that usually shows up on dedicated tactical lights rather than pen-sized tools. There’s also a red SOS mode for emergencies, and a soft tip light that illuminates the writing surface when you’re working in the dark. That last one sounds niche until you’ve actually tried to take notes during a presentation or fill out a form in a poorly lit room.

A green laser with two brightness levels

The Class 3R green laser pointer is the feature that pulls the most weight for the $79.99 price tag. Green lasers are significantly more visible than red ones in daylight and across large rooms, which makes them practical for presentations rather than just a fun addition. It’s the difference between a barely-there red dot that nobody can find on a whiteboard and a bright green point that’s visible from the back row. For a pen flashlight this small, that kind of visibility is a serious advantage.

Olight gave the laser two brightness levels, a detail that suggests they actually thought about how people use laser pointers in real scenarios. Full power works for large conference rooms and outdoor pointing. The O’Pen 3’s lower setting conserves battery and reduces eye strain in smaller spaces. For anyone who’s ever had to borrow a clicker with a barely visible red dot during a meeting, the integrated green laser changes the calculation on whether a pen light is worth the pocket space.

A pen light with hidden USB-C and a meteor shower grip

Charging lives behind a hidden USB-C port that keeps the pen’s silhouette clean when it’s not plugged in. Olight claims a full charge takes about an hour, fast enough that topping off during a lunch break covers you for the rest of the day.

The hidden port is a small detail that matters more than it should, because visible charging ports on EDC gear have a way of collecting pocket lint and looking worse every month. The body itself is machined aluminum with a gently tapered frame that narrows toward the tip.

Olight went with what they’re calling a meteor-shower-inspired grip pattern, which translates to a textured section that provides traction without being aggressive enough to snag fabric. It ships in Black, Wine Red, and Orange, with the first two leaning professional and the third adding a bolder option for anyone who wants their EDC gear to stand out. A spring-loaded clip handles pocket carry, and the overall construction feels closer to a mid-range aluminum pen than a flashlight that happens to write.

A pen light for the EDC crowd

The EDC pen light space is small but growing fast. The crossover between people who carry a good pen and people who carry a small flashlight is bigger than most brands have realized, and Olight is positioning the O’Pen 3 squarely at that intersection.

At $79.99, it’s not an impulse buy, but it replaces a standalone pen light, an EDC pen, a laser pointer, and an emergency signal. For anyone already carrying multiple single-purpose tools, that math starts to work in the O’Pen 3’s favor pretty quickly.
