Round flashlights roll off desks, bulge in pockets, and do one job. The Olight ArkPro is built on a different idea: a flat, phone-shaped body that disappears into a pocket, and four separate light sources inside it. A white flood beam, a focused spotlight, a 365nm UV light, and a green laser, all in a light that is 16 mm thin.
Watch the video above for the hands-on tour and beam demos, then read on for the full output table, how the controls work, and where the ArkPro sits in Olight’s three-model ArkPro lineup.
Four light sources, seven combinations
The pure flood beam is the everyday workhorse: up to 1,500 lumens on Turbo, stepping down through 520 and 100 lumens, a 15-lumen low, and a 1-lumen moonlight mode rated for 14 days. The spotlight is a separate emitter with a tighter beam: up to 800 lumens, 10,640 candela, and a rated throw of 205 metres, which is what you reach for when flood just washes everything out.
The UV light runs at 365 nm in two outputs, a high of 1,200 mW and a low of 360 mW, the wavelength you want for checking currency and IDs, finding pet stains, curing UV resin, and spotting leaks with tracer dye. The green laser (Class 1, up to 0.39 mW on the standard model, with a rated runtime of 226 hours) is independently controlled, and it can run at the same time as any of the other three sources. Three white/UV sources times laser on or off, plus laser alone, is where Olight’s “7 configurations” number comes from.
Controls and carry
A rotary selector on the face switches between flood, spot, and UV. A central button handles on/off and brightness, and a dedicated side switch runs the laser. Colour-coded LEDs around the button report brightness level in white and battery level in green, and there is a lockout mode so it does not turn on in your pocket.
The flat body is 124 x 27 x 16 mm and weighs about 115 grams including the built-in battery. A two-way pocket clip clamps to a pocket or a hat brim, and the base is magnetic, so the light sticks to a car hood or a steel beam and aims where you leave it. The body is 6061 aluminum alloy with an IPX7 rating, meaning it survives submersion to a metre for 30 minutes.
Charging: USB-C and magnetic
The built-in 2,000 mAh lithium polymer battery charges two ways: a USB-C port (about 1.5 hours) or Olight’s MCC magnetic cable (about 3 hours). USB-C is the headline for a lot of buyers, because it means the same cable that charges your phone tops up your light, and you are not stranded when the proprietary magnetic cable is in another bag. Turbo outputs are thermally limited, as on every small light: expect the 1,500-lumen flood to hold for about 4 minutes before stepping down to 520 lumens for the long tail of its runtime.
ArkPro vs ArkPro Ultra vs ArkPro Lite
Olight sells three versions. The ArkPro in this review is the middle model at a US$99.99 list price. The ArkPro Ultra (US$129.99) raises flood output to 1,700 lumens, swaps the body for Olight’s harder OAL aluminum, and adds the ArkBeat breathing accent light. The ArkPro Lite (US$79.99) drops the spotlight and laser in favour of a red light mode, which suits hunters and astronomers protecting night vision. For most everyday carry, the standard ArkPro is the sweet spot: you give up very little output and keep the spotlight and laser that make the design interesting.
The flat-light reality check
Flat flashlights have been a niche idea for years, and the ArkPro is the design that makes the niche make sense, for two practical reasons. Carry: a 16 mm flat body rides in a front pocket or a bag’s flat pocket without the rolling, poking, or printing of a 25 mm tube. Use: a flat light stands on its tail and stays aimed on a desk or a car hood, where a round light needs to be propped against something. The trade-offs are equally real. There is no replaceable battery, the flat shape is a worse fit in a clenched fist than a tube for anyone with tactical habits, and four light sources mean a control scheme you have to learn once. For everyday carry and task lighting, the flat advantages win. For a dedicated duty light, buy a tube.
Frequently asked questions
Is the Olight ArkPro waterproof? It is rated IPX7, tested for submersion at 1 metre for 30 minutes. Rain, drops in puddles, and brief dunkings are fine.
Can the laser run with the white light? Yes. The green laser is independently controlled and can be combined with the flood, spotlight, or UV source, or used on its own.
How long does the battery last? It depends on the mode: up to 14 days on the 1-lumen moonlight setting, 72 hours on the 15-lumen flood low, and a few hours at the high settings. The laser alone is rated at 226 hours.
Is the battery replaceable? No. The 2,000 mAh cell is built in and sealed, which is the trade-off for the thin, water-resistant unibody design.
Verdict
The ArkPro is what happens when a flashlight company designs for pockets instead of spec sheets. The flat shape genuinely carries better than a tube, the four sources cover real jobs rather than spec-padding, and dual USB-C plus magnetic charging removes the last excuse not to keep it topped up. If your current EDC light is a round tube that lives in a drawer, this is the form factor that actually stays on you.
