Imalent SR-32 Review: The New Brightest Flashlight in the World

Introduction

The Imalent MS-18 held the title of the brightest flashlight in the world at 100,000 lumens. That reign is over. The new Imalent SR-32 raises the bar to 120,000 lumens with a rated throw of 2,080 meters, and it is arguably the most capable portable searchlight you can buy right now. It also costs $679.95, weighs nearly five pounds, and gets genuinely hot. This review covers what it does well, where it falls short, and who should actually spend the money.

What’s in the Box

Given the size of the SR-32, the packaging is appropriately generous. It ships in a large soft carrying case with a shoulder strap, so you can carry it slung over your shoulder rather than stuffing it into a bag. Charging hardware is comprehensive: a power adapter that supports 100 watt fast charging with two USB-A and two USB-C ports, plus a 100 watt USB-C to USB-C cable. Imalent also includes six spare O-rings, an Allen wrench, a couple of screws, and the user manual.

The flashlight itself comes with a handle that has its own button, mirroring the switch on the body. Both buttons perform identical functions, which is convenient when you are wearing gloves or repositioning the light.

Specifications and Key Features

The headline numbers are 120,000 lumens of maximum output, 2,080 meters of throw, and 1,090,000 candela, which Imalent claims is the longest throw of any LED flashlight. Pushing that output are 32 Cree XHP 50.3 High LEDs rated for 50,000 hours of lifespan. The body is aluminum with a type III hard anodized finish, the lens is toughened ultra-clear mineral glass with an anti-reflective coating, and the light uses an aluminum smooth reflector.

Because this much output generates serious heat, the SR-32 integrates three cooling fans running at 10,500 RPM. The high-capacity rechargeable battery pack doubles as a power bank, supports 100 watt fast charging, and refills in about an hour and a half. Durability ratings include a 0.5 meter impact resistance and an IP56 dust and waterproof rating. In practice, IP56 means it is rain proof but not submersible. Given all the fan vents on this light, that rating is genuinely impressive. A two-year warranty rounds out the package.

UI, Modes and Runtime

The SR-32 offers seven modes plus strobe, controlled by dual switches with no half-press functionality: one press on, one press off. The built-in OLED display shows your brightness level, voltage, lock status, strobe indicator, and heat warning, then fades after a few seconds. Surprisingly for a light this powerful, the lowest mode is a 30 lumen moonlight mode, a big step down from the MS-18’s 700 lumen floor.

The runtime ladder is worth studying before you buy. Moonlight runs 360 hours, low at 1,500 lumens runs 15 hours, mid-low at 4,500 lumens runs 4 hours 25 minutes, middle one at 9,000 lumens runs 2 hours, and middle two at 25,000 lumens runs 55 minutes with the fans kicking in. High at 50,000 lumens lasts 60 seconds before stepping down, and turbo at 120,000 lumens lasts just 45 seconds before dropping to 25,000 lumens for another 45 minutes. Mode spacing from moonlight to high feels well judged, though there is an awkward gap between 50,000 and 120,000 lumens with nothing in between.

Lockout is handled with four quick presses from off, shown by a lock icon on the display, which is simple and absolutely necessary on a light this bright. There is also a manual fan mode: press and hold either button for about five or six seconds to activate the cooling fans if the light feels too hot. One genuine gripe: a single accidental press on the body switch instantly blasts out whatever mode you last used, and at 25,000 lumens that is blinding. Press-and-hold activation would have made this light much safer to handle casually.

Heat Management and the Turbo Test

To assess heat, a two-minute turbo test measured head and body temperatures. After one minute on turbo, the head reached about 135 degrees Fahrenheit while the battery body sat around 94.6 degrees, which is manageable. At two minutes the head held around 134 degrees, with one spot peaking at 139 degrees, while the body climbed to about 105 degrees. Turbo visibly steps down rather than shutting off abruptly.

The practical takeaway: the body stays tolerable, but the head is dangerously hot. If you plan to run turbo for any length of time, wear gloves, and expect visible heat fog on the lens during extended use.

Beam Performance in the Field

In a dark backyard, the SR-32 is almost absurd. Even the 1,500 lumen low mode easily reaches trees and a distant barn. The beam profile is fairly wide with a defined hot spot and a broad, softly defined outer perimeter rather than a crisply cut edge. At middle two, the fans audibly kick in. High at 50,000 lumens lights up the entire yard and lands on trees well beyond the barn without strain.

Turbo at 120,000 lumens turns night into something approaching daylight. It is the kind of output that makes casual use genuinely hazardous for anyone nearby, but for search and rescue, security, hunting, or distress signaling, that raw power is exactly the point.

How It Compares to the Imalent MS-18

The MS-18 was mind-blowing at 100,000 lumens with a 1,350 meter throw, and it remains a monster. The SR-32 improves on both figures substantially, jumping to 120,000 lumens and 2,080 meters of throw. It also adds a much lower floor, with a 30 lumen moonlight mode versus the MS-18’s 700 lumen minimum, which makes the newer light far more versatile when you do not want to blind everyone in the room.

If you already own an MS-18, the SR-32 is a meaningful upgrade rather than an incremental one, particularly for long-distance search work.

Buying Advice

So who is the SR-32 for? Search and rescue is the obvious answer, and this is arguably the best search and rescue flashlight available right now. It also fits security work, hunting, and distress signaling. If your job is to find things at night, at distance, this is the tool.

Be honest about the trade-offs before buying. At $679.95 it is out of reach for most people, the 4.89 pound (78.2 ounce) weight makes extended handheld use tiring, the 0.5 meter impact resistance means a drop could break something, and the head gets hot enough to require gloves on turbo. This is not a backpack light; it lives in a truck or a response kit.

If those limitations fit your use case, nothing else comes close.

Conclusion

The Imalent SR-32 delivers a genuinely new benchmark for portable lighting: 120,000 lumens, 2,080 meters of throw, thoughtful extras like a moonlight mode and 100 watt charging, and a simple, safe UI. The heat, weight, and price are real costs, but for serious search and illumination work, saying it is impressive is an understatement.
