The Olight O'Pen Glow Black (OPENGLOWBK) is a 4-in-1 rechargeable penlight that writes, lights and points. It combines a 120-lumen pen clip light, a 0.2-lumen pen tip light for writing in the dark, a green laser pointer and a ballpoint pen in one slim aluminum body — a genuinely useful EDC pen light for clinicians, technicians, presenters and anyone who takes notes after dark. Going Gear is an authorized Olight dealer.
Key Features
- 4-in-1 design — pen, pen clip LED light, pen tip LED light and green pointer beam
- Four clip-light output levels: 5, 20, 60 and 120 lumens, so you can dial brightness to the task
- Soft 0.2-lumen pen tip light (4000K) puts even illumination right on the page while you write
- Green laser pointer at 510–530 nm, Class 1, 0.39 mW max, with up to 6 hours of laser runtime
- Separate switches for white light and laser so the two are never confused in use
- Lockout mode prevents accidental activation in a pocket or bag
- Recharges by dropping the pen into the included charging base — roughly 55 minutes to full
- Replaceable ballpoint refill; the light and charging function are built into the pen body
