If you've been shopping our EDC lineup you've probably run into the SPERAS name a few times and not been totally sure where it fits next to Convoy, Wuben, and OLIGHT. Fair question — SPERAS doesn't chase one niche. The brand runs a duty-style tail-switch series, a throw-focused search light, a couple of pocket-sized 18350 EDC lights, a clip-on work light, and a charger that doubles as a power bank. Here's how the lineup breaks down so you can pick the right one instead of guessing.
EDC Pocket Lights: ARC Ti and M4 Mini
If what you want is a light that lives in a pocket and you forget about until you need it, start here. The SPERAS ARC Ti is a titanium keychain light — 150 lumens on high, 10 on low, USB-C charging under the removable head. It's the light you clip to keys and never think about, closer in spirit to an OLIGHT iTHX than anything tactical.
Step up in size and you get the SPERAS M4 Mini V2, which is a different animal entirely — 2000 lumens and 700 meters of throw out of an 18350 cell, in a body still small enough for a front pocket. That kind of throw-to-size ratio is unusual; most lights that reach 700m need a 21700 and a much bigger head. Run out of runtime and the M4 extension tube swaps the 18350 for a longer-lasting 18650 without buying a second light.
Duty-Style Tail Switch: E21 and ST20
The E21 and ST20 are built around the same idea: a 2-in-1 tail switch that gets you to turbo or strobe in one motion, no cycling through modes under pressure. The SPERAS E21 runs a 21700 cell for 2000 lumens with real legs behind it, while the SPERAS ST20 takes the same tail-switch approach into an 18650 body at 1300 lumens with a 326-hour low-mode runtime. If you carry for security, property checks, or just want a light that behaves predictably when your hands aren't being careful, this is the pair to look at over the general EDC lights above.
The EST Series: SPERAS' Deepest Bench
EST is where SPERAS puts most of its lineup, and it's worth knowing the differences because they're not just cosmetic. The EST2 and EST Mini both put out 1900 lumens and 211m of throw — the EST2 runs an 18650 for more runtime, the EST Mini runs an 18350 for a smaller footprint. Same performance, different tradeoff between size and legs.
The EST MAX pushes further to 2500 lumens and 279m, but runs a proprietary 18650 cell — it doesn't take a standard 18650 off the shelf, so plan on charging the included battery rather than swapping in spares from your Convoy stash. And if throw is the whole point, the EST Plus Thrower trades lumens for distance — 1600 lumens sounds modest next to the EST MAX until you see it reaches 726 meters, more than double. That's a search-and-property-check light, not a walk-the-dog light. It also takes CR123A as a backup, which the rest of the EST series doesn't.
SPERAS U2: The One That Charges Your Phone Too
The SPERAS U2 is the outlier in the lineup — 5000 lumens off three Luminus SST40 emitters, dual built-in 18650 cells, a rectangular body designed for heat dissipation instead of a round tube, and a bike mount included in the box. Pair it with the wireless remote pressure switch and you've got hands-free turbo/strobe control, which is the point if you're running it on a bike or need to trigger it without breaking grip. It's less an EDC light and more a floodlight that happens to be portable — camping, property lighting, or anywhere 5000 lumens actually gets used.
Don't Forget the Charger
Most of the EST and E-series lights run off proprietary or standard 18650/21700 cells with USB-C charging built into the light itself, so you often don't need a separate charger day to day. But if you're carrying spares or want to top off a battery outside the light, the SPERAS PD21700 charges both 21700 and 18650 cells and doubles as a USB-C power bank — drop a charged cell in and it'll top off a phone in the field, the same trick as the Yonii PD2 we've covered before.

One Light We Almost Filed Under "Not a Flashlight"
The SPERAS U1 doesn't fit the EDC-pocket-light or duty-tail-switch categories above — it's a clip-on work light with a magnetic base, a motion sensor, and RGB modes, meant to hang off a hat brim, a bag strap, or stick to something metal and light up a work area hands-free. 500 lumens, IP65-rated, USB-C rechargeable. If you're picking a SPERAS for hands-free task lighting rather than a beam you point and shoot, this is the one, not the M4 or ST20.
Picking the Right One
Rough guide: ARC Ti for a keychain light you forget you're carrying, M4 Mini V2 if you want serious throw in a small body, E21 or ST20 if a tail-switch matters more than raw lumens, EST2/EST Mini for a general-purpose duty light, EST MAX if you want the most lumens SPERAS makes short of the U2, EST Plus if distance is the actual requirement, U2 if you need floodlight-level output, and U1 if you need a light that clips somewhere and stays there. Browse the complete SPERAS lineup to compare specs side by side, and if you're still torn between SPERAS and another brand in a similar category, our EDC flashlight buyer's guide covers how to weigh those tradeoffs generally.
