The Best Flashlights: 4 Compared (and One to Skip)

RBE top pick

Fenix PD36R Pro

Check price on Amazon See why it wins Compare all

The Fenix PD36R Pro is the one light most people should buy: a removable, USB-C-rechargeable battery, honest sustained output, and a beam that works up close and at distance. The ThruNite Archer 2A Pro is the smart cheap companion that never leaves you battery-less because it also runs on ordinary AAs.

The lumen number on a flashlight box is mostly marketing. The advertised "peak" is a burst the light holds for a few seconds before it steps down to protect itself from heat, so sustained brightness and runtime matter far more than the big figure, and the "990,000-lumen" lights sold online are physically impossible. We weighed four lights for the garage, dog walks, and power outages on what actually holds up: two clear buys, one that depends on how you carry it, and one obvious skip.

RBE top pick

Fenix

Fenix PD36R Pro

Buy it

One rechargeable light that genuinely does everything, with a real removable battery and honest sustained output.

Best for: Anyone who wants a single, reliable light for the house, garage, car, and outages.

$$$ · premium

Why we like it

• Removable 21700 Li-ion with built-in USB-C charging, so a spare cell means no downtime
• Holds a strong, usable output well after turbo steps down, with long runtime on lower modes
• Balanced beam that floods a workbench and still reaches down the driveway; waterproof to 2 meters with an impact-resistant aluminum body
• Two tail switches (one for on/off, one for modes) are fast and hard to fumble

Know before buying

• Like every light, its top turbo number drops within seconds; the sustained figure is what you actually get
• Premium price, and larger than a keychain light

ThruNite

ThruNite Archer 2A Pro

Buy it

A cheap, simple light that ships with a USB-C rechargeable cell and also runs on AA batteries you already own.

Best for: People who want a no-fuss backup light that can always fall back on AA batteries.

$ · budget

Why we like it

• Also runs on two common AA cells, so a flat rechargeable never leaves you without light
• Deep smooth reflector rated to 365 m, so it reaches the far fence or a dog across the yard (ThruNite's copy says 1,020 lumens; its spec table lists 600-700)
• Tactical tail switch with momentary on, a side switch for six modes, and a green standby pulse that helps you find it in the dark
• Two-way deep-carry pocket clip and an easy price to keep one in every drawer and glovebox

Know before buying

• ThruNite's own spec table lists 600-700 lumens max against 1,020 in its copy; either figure is the lowest of the three named lights, well under the PD40R's 3000
• The included 1900mAh cell is smaller than the 5000mAh 21700 in each Fenix

Fenix

Fenix PD40R V3.0

It depends

A premium 3000-lumen, 500 m light run entirely from a rotary switch, heavier and more specialised than most people need.

Best for: Someone who wants the brightest, longest-reaching light here for the garage or worksite and does not mind the extra weight.

$$$ · premium

Why we like it

• A 3000-lumen maximum and a rated 500 m beam distance, the brightest and farthest-reaching here
• Removable 5000mAh 21700 with USB-C charging in about 3 hours, and a mechanical rotary switch with a hard stop before the flashing modes
• IP68 sealing, and a flat tail that lets it stand on end

Know before buying

• Fenix says it steps down automatically at 60°C, and its 2 hour 40 minute Turbo runtime counts the time spent at reduced output
• 198 g with battery, more than the PD36R Pro, and priced at the premium end
• No tail switch, so every on, off and mode change goes through the rotary ring

We'd skip it

Generic / no-name

Anjoet "990,000-Lumen Tactical" Zoom Flashlight (no-name import)

Skip it

The archetypal fake-lumen "military tactical" light: an impossible number on the box and a cheap emitter behind it.

Best for: No one; it is the category this guide exists to steer you away from.

$ · budget

Why we like it

• Cheap up front
• Zoomable head looks feature-rich in listings

Know before buying

• The advertised lumen count is physically impossible; real output is a small fraction of the claim
• Low-quality emitter with poor heat management, so it dims fast and can fail early
• Zoom lens wastes light and creates a blocky beam; sealing and impact resistance are usually unrated
• Ships with an unprotected or mystery-brand cell and effectively no warranty or support

How we judged the field

We do not run our own light lab, and we will not pretend to. Instead we synthesize independent testing, teardown reports, and the patterns that repeat across large numbers of owner reviews, then weight all of it for real use: a garage light, a dog-walk light, and a light you can find and trust during a power outage. The single most important thing we screen for is the gap between a flashlight’s advertised peak and what it actually sustains. Makers quote a “turbo” number the light can hold for only seconds before it steps down to protect itself from heat, so a light that settles at a steady, usable output for hours beats one that flashes a huge figure and fades. From there we looked at beam shape, wide flood for close work versus focused throw for distance; battery type and charging; waterproof and impact ratings; the interface; and size, from a pocket everyday-carry light to a chunky work light. We also kept the category’s worst offenders in view as a control, because the “990,000-lumen tactical” lights are a permanent reminder that the number on the box is often pure fiction.

This is the light most people should own. It takes a removable 21700 lithium-ion cell and charges over USB-C in the body, so you are never stranded, and a charged spare cell turns a dead light into a two-second swap. What earns the buy is not its top number but its behavior after the top number is gone: it steps down from turbo like everything does, then holds a strong, genuinely useful output, with long runtime once you drop to the mid modes you will actually live in. The beam is a sensible balance that throws enough light across a driveway while still flooding a workbench, the aluminum body is waterproof to 2 meters and impact resistant, and the dual-switch interface, two tail buttons with one for on and off and one for modes, is quick and hard to fumble in the dark. The honest caveats are simple: the headline turbo figure is a burst, not a promise, and this is a mid-size light rather than a keychain companion.

The Archer 2A Pro earns its place by being the opposite kind of smart buy: cheap, simple, and always ready. It ships with a 1900mAh USB-C rechargeable cell and also runs on two ordinary AA batteries, so you can keep AAs in a drawer for years as a fallback that will always work. ThruNite’s copy rates it at 1,020 lumens and 365 m from a deep smooth reflector (the spec table on the same page lists 600-700 lumens), which suits spotting the far fence line or a dog at the edge of the yard; the tail switch gives you momentary on for quick checks, a side switch steps through six modes, and a green standby pulse helps you find it in the dark. It gives up peak output to the Fenix lights, but as a no-fuss backup for the glovebox, the junk drawer, or a coat pocket, it is hard to beat for the money.

The PD40R V3.0 is a genuinely good light that is right for fewer people than the two buys. Its strength is raw output and reach, 3000 lumens and a rated 500 m beam, and it pairs that with a removable 5000mAh 21700 cell that charges over USB-C in about 3 hours and a mechanical rotary switch with a hard stop before the strobe and SOS modes, which works well in gloves. It is IP68-sealed and stands on its tail. The reasons it is a “depends” rather than a “buy” are specific: there is no tail switch, so every on, off and mode change goes through the rotary ring; Fenix says the light steps down automatically once it reaches 60°C, and its 2 hour 40 minute Turbo runtime counts the time spent at reduced output; at 198 g with battery it is heavier than the PD36R Pro for pocket carry; and it sits at the premium end of the price range. If you specifically want the most output and reach here and like a rotary interface, it is excellent. If you want one light to do a bit of everything, the PD36R Pro is the smarter spend.

This stands in for an entire genre of no-name “military tactical” lights, and it is the clear skip. The advertised lumen count is not exaggerated, it is impossible; real output is a tiny fraction of the claim, produced by a low-grade emitter with poor heat management that dims within moments and can fail early. The zoom head that looks so capable in listings actually throws away light and produces a blocky, uneven beam. Waterproofing and impact resistance are typically unrated because the light would not pass, and these lights usually ship with an unprotected or mystery-brand battery and no meaningful warranty. Spending a little more on any of the reputable lights above gets you honest output, a real battery, and support that exists.

Fenix PD36R Pro vs ThruNite Archer 2A Pro: which should you buy?

These are the two we would actually hand to a friend, and the choice between them is really a choice about how you want to power a light. The PD36R Pro is the do-everything answer: more sustained output, a longer-reaching yet still floody beam, USB-C charging built in, and a removable cell you can swap or upgrade. It costs more and it is bigger, but it is the one light that covers the house, the car, the garage, and an outage without compromise. The Archer 2A Pro is the answer if you want a light that never depends on charging: alongside its own rechargeable cell it takes two AAs you can buy anywhere, stores for years without babysitting, and costs little enough to own several. Buy the PD36R Pro as your primary, everyday light; buy the Archer 2A Pro as the cheap, always-ready backup, and many people will happily own both.

What to look for

• Sustained output, not peak lumens. Find the brightness a light holds after turbo steps down; that is what you actually get. Treat any five- or six-figure lumen claim as a reason to walk away.
• A real, ideally removable battery. A rechargeable 18650 or 21700 with USB-C gives the best output and runtime, and a removable cell lets you carry a charged spare. AA lights trade peak output for batteries you can buy anywhere.
• The right beam. Wide flood for close work; focused throw for distance; a balanced beam if you want one light for both.
• Waterproof and impact ratings you can read on the spec sheet. IPX8 or IP68 means it survives submersion; a drop rating in meters means it survives being dropped. Missing ratings are a red flag.
• A simple, quick interface you can operate in the dark without cycling through a dozen modes.
• A reputable brand with a warranty. Support that exists is part of what you are paying for.

Our final take

Buy on sustained output and a real, ideally removable battery, and ignore the big number on the box. The Fenix PD36R Pro does that better than anything here and is the light we would recommend to almost anyone; the ThruNite Archer 2A Pro is the inexpensive companion that also takes AAs that is always ready when you need it. The Fenix PD40R V3.0 is a fine premium light for the specific person who wants maximum output and reach and will accept the extra weight and the fast turbo drop-off. And the no-name “990,000-lumen” lights are exactly what their impossible numbers suggest: skip them, and put the money toward a light that performs the way its box implies.
