Olight ArkPro Lite Review: The Flat Light Without the Extras
The short version: The Arkfeld Pro formula — flat body, sealed cell, multi-source — with the green beam swapped for a red light and $20 trimmed off the price. 1,200 lumens, 94 m throw, a genuinely useful UV, and Olight's magnetic charging. The best entry point into the flat format if the laser is expendable.

Who this light is for
The ArkPro Lite exists because Olight noticed something about who was buying the Arkfeld Pro: a large share used the white light and the UV and never once flicked the green beam to the selector's third stop. The Lite removes that stop. What remains is a flat, pocketable slab with a 1,200-lumen white light and a 365 nm-class UV — the two sources most buyers actually used — at $70 instead of $90.
The red light deserves its own mention: it's not a filler mode. Red preserves night vision, doesn't spook animals, doesn't wake a sleeping partner, and is the correct color for checking a map or a dash at night. Between red, UV, and a competent white side, this covers the three things most people use a small light for — and Olight explicitly markets the UV for pet urine detection, which tells you a lot about the buyer.

All figures below are Olight's published ratings, not our measurements.

| Light sources | White LED + UV + red light |
| Switch | Center button, source selector |
| Battery | Sealed rechargeable (built in) |

The value case
Run the numbers on the flat-light market: the Arkfeld Pro is $90, the Streamlight Wedge is $100, and the Lite is $70. For that $20 saving over the Pro you give up one laser — a Class 3R pointer most owners use a handful of times a year — and keep everything that makes the format worth carrying: the slim profile, the UV, the sealed-battery simplicity, and the polish.
Against the Wedge the comparison is starker. The Lite adds UV and red, charges over USB-C and magnetically, and costs less. The Wedge counters with Streamlight's duty-grade reputation and a more conventional switch layout. For pure utility per dollar, the Lite wins the flat-light trio.
Where it falls down
Same sealed battery, same risk. The flat format demands a built-in cell, and the Lite shares the Arkfeld family's structural weakness: when the cell dies, the light does. At $70 the warranty math is easier than at $90, but it's the same design trade.
1,200 lumens is still a burst. A slab this thin sheds heat poorly; turbo steps down within a minute. The Lite's honest home is its mid levels, where it's plenty for rooms and paths.
No laser, and you'll notice occasionally. The green beam was the Arkfeld Pro's presentation-pointer and long-range attention-getter. If you use that feature even monthly, pay the extra $20 and buy the Pro. The Lite is the right choice only when the laser was truly dead weight.
IPX7, not IPX8. Submersion-safe for rain and drops into shallow water, but one rating step below the round Baton 4 Pro.
Pros
- Cheapest way into the flat-light format
- UV retained — the feature most owners actually used
- Red light for night vision and pets
- 1,200 lm white side with a real 94 m throw
- USB-C plus magnetic charging
Cons
- Sealed battery — format-wide trade
- Turbo steps down quickly
- No green beam if you wanted it
- IPX7 rather than IPX8
What to buy instead
| If you want… | Buy this | Why |
|---|---|---|
| The green beam back | Arkfeld Pro | + $20, adds the 3R laser |
| More output, round body | Baton 4 Pro | 1,600 lm, IPX8, dual switches |
| Duty-brand flat light | Streamlight Wedge | 1,000 lm flat, no UV |
| Replaceable battery | Fenix E18R V2.0 | 16340 or CR123A, IP68 |
The verdict
The ArkPro Lite is the flat light for people who liked the idea of the Arkfeld Pro more than its price. You keep the format, the UV, the red light, and a genuinely bright white side; you give up a laser that most owners barely used. At $70 it's the easiest flat-light recommendation on this site.
Buy it if you want one slim object covering white light, UV inspection, and night-safe red. Step up to the Arkfeld Pro only for the beam, and step across to the E18R V2.0 if a replaceable battery is non-negotiable.
Frequently asked questions
ArkPro Lite vs. Arkfeld Pro — what do you actually give up?
Only the green laser beam and 100 lumens (1,200 vs 1,300). The flat body, the UV, the red light, the sealed battery, and the charging system carry over. The Pro's beam is worth the $20 only if you'll use a presentation pointer or long-range attention-getter regularly.
What is the red light for?
Night-vision preservation, checking maps or dashboards without killing your dark adaptation, not waking a partner, and not spooking animals. It's a legitimately useful third source rather than a marketing line.
Can the ArkPro Lite's battery be replaced?
No — the rechargeable cell is sealed into the flat body. That's the structural trade of the format at every price point, from the Lite to the Arkfeld Pro.
Is the UV the same as the Arkfeld Pro's?
The Lite carries Olight's UV in the same flat format, marketed for pet urine detection. The Arkfeld Pro's UV is the higher-output 365 nm professional-class emitter; the Lite's is the more modest implementation of the same idea. Both beat the cheap 395 nm afterthoughts on most competitor lights.
