V Tiger S2 Review: A Slim Everyday Carry Flashlight With Real Power
The V Tiger S2 packs up to 1,600 lumens into a finger-sized body, with a UV option, magnetic tail, and USB-C charging. Here is how it performs in everyday use.
Introduction
Everyday carry flashlights live or die on one thing: whether you actually want to keep them in your pocket all day. The V Tiger S2 is built squarely around that idea. It is slim, flat, and compact, yet it puts out a claimed 1,600 lumens at turbo, which is a lot of output for a light about the same size as a finger.
It comes in two versions: a dual white version and a UV version, both offered in blue, green, black, and titanium. The unit tested here is the titanium UV version, and after extended use it holds up well as a genuinely pocketable, capable light with a few trade-offs worth knowing about.
A Form Factor Built for Everyday Carry
The dimensions are where this light wins you over. It measures 3.69 inches long, 0.98 inches wide, and just 0.45 inches thick, not counting the pocket clip. On a scale it weighs exactly 3 oz, or 86 g. That flat, slim profile means it disappears into a pocket instead of dragging it down, which is exactly what most people want from an EDC light.
Despite the small size, the build feels considered. It carries an IPX7 rating, meaning it is submersible in up to 3 feet of water, though the dust-proofing portion of the rating was not tested. It also has a 1.5 m impact resistance rating, and a weatherproof USB-C charging port on the side of the body hidden under a rubber flap that keeps dirt and mud out.

Design, Beam Profile, and the UV Option
The titanium version looks genuinely good. Angled cuts along the body give it a distinctive, machined aesthetic, and the single luminous SFT12 LED sits behind an aluminum alloy reflector with an orange peel texture. That texture spreads the beam out nicely, so the profile is even and diffuse rather than tightly focused with a harsh hotspot. It is not extremely floody or extremely spotty, which suits everyday tasks well. The white light reads as neutral white rather than cool or warm.
The UV version swaps one of the two LEDs for a UV emitter with two levels: a 350 mW low and a 1,000 mW high on press and hold. In testing it instantly activates glow-in-the-dark tape, and it works for tasks like detecting counterfeit bills. The dual white version instead uses two SFT12 LEDs.

Controls are handled by a single metal switch dead center on top. Just above it, four LEDs show the battery level on boot-up for about 3 to 4 seconds, then fade out. No button gymnastics required to check your charge level. The back of the light carries a deep carry pocket clip with solid tension, a lanyard hole at the bottom, and a magnetic tail strong enough to hold the entire light horizontally against a knife blade. Because the tail is flat, it also tail-stands, which is a big plus.
User Interface and Charging
The UI is simple and well thought out. A single short press turns the light on and off. While on, press and hold to cycle through the four cyclable levels: low, medium, high, and turbo. With the light off, press and hold to activate moonlight mode directly, since moonlight is not part of the main cycle. Mode memory works in both white and UV modes, so the light returns to your last-used level.
On the UV version, a double press toggles between white and UV light, and the same press-and-hold cycles brightness within each mode. Lockout mode is easy to remember: with the light off, press and hold past moonlight until it flashes, and it is locked. Reverse the steps to unlock.
One underrated feature is charging pass-through. Plug in the USB-C cable and the indicator LEDs flash, but you can still use the flashlight while it charges. That is genuinely useful for a light you may reach for at any moment.
Brightness and Run Time in the Real World
V Tiger publishes unusually transparent specs here. Moonlight is 1 lumen for a claimed 19 days of run time. Low is 10 lumens for 62 hours. Medium, the sweet spot, is 120 lumens for 4.2 hours. High is 350 lumens for 1 minute before stepping down to 250 lumens for another 2.5 hours. Turbo is 1,600 lumens for 30 seconds, stepping down to 300 lumens for 120 minutes. Strobe runs the full 1,600 lumens for 2 hours. The UV levels claim 3 hours on 350 mW and 7.5 hours on 1,000 mW. That kind of honesty about turbo run time is rare, and it deserves credit.
Independent testing told a slightly different story. High measured around 280 lumens, stepping down after roughly 1 minute 10 seconds to around 163 lumens. Turbo measured around 1,100 lumens and stepped down almost instantly, settling near 300 lumens after about 34 seconds. Even so, real-world output is plenty bright for everyday carry. At medium, the beam easily reaches distant trees and a barn across an open yard.

One fair criticism is mode spacing. Medium at 120 lumens is useful, but many users spend most of their time there, and a higher medium around 350 lumens with a high near 750 would have been a better balance. Still, the inclusion of a true 1-lumen moonlight mode is appreciated.
Who Should Buy the V Tiger S2
If you want a flashlight that vanishes into a pocket and still delivers serious output when needed, this is an easy recommendation. The deep carry clip, flat profile, magnetic tail, simple UI, and pass-through charging all serve the everyday carry use case directly. It is at its best as a daily companion rather than a dedicated thrower or long-runtime work light.
Availability matters here: the V Tiger S2 launched through a Kickstarter campaign that started on December 13th, and the Super Early Bird tier was listed at $26, a 56% discount. Anyone who can get it for under $30 is getting excellent value.

Things to Consider Before Buying
The main trade-off is the built-in 1,100 mAh lithium-ion battery. In a body this slim there is arguably no room for anything else, and the light has survived near-full days of use on a charge, but a replaceable battery would still add peace of mind for a light that may sit unused for long stretches. The lithium-ion chemistry over lithium polymer is also a curious choice for this shape.
The other caveat is output versus claims. Measured lumens came in below the published figures, especially at turbo, and turbo is a short burst rather than a sustained mode. Neither issue ruins the experience, but both are worth knowing before buying.
Conclusion
The V Tiger S2 gets the everyday carry formula right: slim, flat, light, well built, and bright enough for nearly any daily task. The UI is simple, the mode memory and lockout work exactly as you would hope, and the UV option adds genuine utility. Between the below-spec lumen measurements and the sealed battery, it is not flawless, but as a pocket light at Kickstarter-era pricing it is a strong pick. If you can find it for under $30, it is worth grabbing.
