Honest review, UAE stock. We sell this pen, and we’ll still tell you the catch.
The 30-Second Verdict
The Olight O’Pen Glow (AED 378) is a proper aluminium ballpoint pen that hides a genuinely useful 120-lumen flashlight in the clip — plus a party trick nothing else in our shop has: a tiny LED at the pen tip that lights the page while you write in the dark.
The catch? The battery is a tiny 110mAh cell, so think in minutes, not hours: roughly 14 minutes at the full 120 lumens before it steps down to 60. It’s splash-resistant (IPX4) on the upper half only. And despite what you might expect from the O’Pen family — there is no laser and no SOS on the Glow. Those live on its sibling, the O’Pen 3, at exactly the same price. Buying between the two is a genuine fork in the road, and we’ll map it below.
Who Is It For?
Engineers, site supervisors, nurses on night rounds, hotel and facilities staff, and anyone who signs paperwork in badly lit places — loading docks at 5am, plant rooms, delivery yards. Also, frankly, it’s one of the best corporate-gift lights we stock: it looks like a premium pen first and a gadget second.
It is not for anyone who wants a primary torch. At 120 lumens and a 14-metre beam this is a task light for arm’s-length work. If you want one pocket light that does everything, that’s the EDC flashlight guide’s territory — start with the i3T 2 EOS (AED 109).
What Does “4-in-1” Actually Mean?
Olight’s box says 4-in-1. In plain terms you get: 1) a smooth aluminium ballpoint pen (black refill fitted, a spare blue refill in the box), 2) a 120-lumen white LED built into the clip, 3) the glow trick — a 0.2-lumen LED at the pen tip that softly lights exactly where the nib meets the paper, good for about 2.5 hours, and 4) a magnetic badge so the pen snaps onto a shirt pocket, whiteboard or toolbox.
One thing it is not: a laser pointer. Our own product title mentions the O’Pen family’s green laser, but check the spec sheet — the Glow has no laser hardware at all. If you present slides for a living, stop here and buy the O’Pen 3 instead.

Specs above are from the live listing of the exact units in our Dubai warehouse, not the generic global page. New to lumen numbers? Here’s how many lumens you actually need.
Light Modes & Real Runtimes
| Mode | Output | Runtime (spec) | Honest read |
|---|---|---|---|
| High | 120 → 60 lm | 14 + 21 min | Full brightness for ~14 min, then half |
| Med | 60 lm | 45 min | The realistic working mode |
| Low | 20 lm | 110 min | Reading, close inspection |
| Moon | 5 lm | 5 h | Bedside, cinema-polite |
| Pen tip | 0.2 lm | 2.5 h | Writing in the dark — the whole point |
Read that table the way we’d tell you across the counter: this is a 60-lumens-for-45-minutes device with a 120-lumen burst, hanging off a 110mAh cell. That’s fine — it charges on its little desk base between uses — but it’s a pen with a light, not a light with a pen.
Living With It in the UAE
Desk-and-glovebox duty is where this pen earns its keep: the aluminium body shrugs off keys and coins, and the clip light is exactly right for junction boxes, hotel-room safes and finding the black abaya bag in a black car boot at night. The magnetic badge holds on a kandura pocket and on steel racking. The charging base lives happily next to a monitor — drop the pen in, it’s always topped up.
Heat note: the spec sheet doesn’t publish an operating temperature for the Glow, so we won’t invent one — but like all lithium-polymer gear, don’t leave it on the dashboard in July. Our summer heat guide explains why that kills batteries.
What We’d Change
Three honest gripes. First, IPX4 — and only on the upper half — means rain is fine but a drop in a bucket isn’t; if you work around water, read our IP ratings explainer before deciding. Second, the cool 5700K clip light is efficient but clinical; a neutral option would be kinder on paper documents. Third, at AED 378 it sits in serious-gift territory while a Oclip Pro (AED 159) out-lumens it for less than half the money — you’re paying for the pen, the machining and the trick tip, and you should know that going in.

Should You Buy It?
Yes, if you write things down for a living in places where the lights are off, or you need a gift for someone who does — it’s the rare gadget that gets daily use. No, if you wanted a laser (O’Pen 3), a real torch (EDC guide), or maximum lumens per dirham (budget EDC picks).
