Imalent BL50 Review: 3,600 Lumens and UV in a Compact Dual-Light Flashlight
A compact dual light source flashlight pairing a 3,600 lumen LED with 365nm UV, plus an OLED display and IPX8 rating, with some real trade-offs to weigh.
Introduction
The Imalent BL50 is a compact dual light source flashlight that combines a high-output white LED with a 365nm ultraviolet light in one small body. It promises up to 3,600 lumens, a 428-meter throw, and a maximum runtime of 280 hours, all controlled through two switches and monitored on a built-in OLED display. That combination makes it an interesting proposition, but it also raises a fair question: who exactly is this light for? After spending time with it, the answer is more specific than the marketing suggests.
Design and Build Quality
The BL50 has a genuinely unique shape. The rounded aluminum alloy body with a type III hard anodized finish feels comfortable in the hand no matter how you grip it, overhand or underhand. It measures 3.68 inches long, 1.36 inches tall, and about 1.1 inches thick, weighing in at 156 grams, roughly 5.5 ounces. In the box you get the flashlight, an adjustable lanyard, a USB-C to USB-C charging cable, and a user manual. It comes in four colors; the version here is black.

Build quality feels high throughout. The lens is mineral glass with an anti-reflective coating, sitting over a smooth aluminum reflector and a single Cree XHP 50.3 High LED rated for about 50,000 hours with a color temperature of 5700 to 6700 Kelvin. The light carries an IPX8 rating, meaning it is submersible up to 6 feet (the dust side of the rating was not tested), plus 1.5-meter impact resistance. Notably, Imalent managed all of this alongside an OLED display and a USB-C port with a flap, which is not a common combination.
Specs and Brightness Levels
The headline numbers: a maximum output of 3,600 lumens, a maximum throwing distance of 428 meters, a max intensity of 45,780 candela, and a max runtime of 280 hours, which works out to 11 days and 16 hours. Inside sits a built-in 3,000mAh battery that rapid charges through the side USB-C port in about an hour and a half.
The brightness ladder is where things get a little odd. There are six white light levels plus strobe, but instead of the usual low and medium naming, Imalent uses Middle Low, Middle One, and Middle Two. Middle Low is 200 lumens for 6 hours and 28 minutes, Middle One is 600 lumens for 3 hours and 10 minutes, and Middle Two is 1,200 lumens for 1 hour and 16 minutes. High is 2,000 lumens for 3 minutes 30 seconds before stepping down to 1,200 lumens for another 70 minutes, and Turbo hits 3,600 lumens for roughly 70 seconds before stepping down to 1,200 lumens for another 68 minutes. The naming makes it hard to identify a true medium, but 600 lumens for over three hours on Middle One is an excellent practical sweet spot. Moonlight is 5 lumens rather than the 1 lumen many would prefer, though it is where the maximum 280-hour runtime lives.
UI and the OLED Display
Control is split across two switches. The tail switch, called power switch number one, handles the main brightness levels: a short press toggles on and off, and a press-and-hold cycles through the levels. A double press from either on or off jumps straight to 3,600-lumen Turbo, and another double press activates strobe. Three rapid presses lock the light out, and it also has brightness memory, so it turns back on at your last used level.

The side switch, power switch number two, is dedicated to convenience: a single press gives instant access to Moonlight, which is a smart touch since most lights require a press-and-hold. A double press activates the 365nm UV light, and you can even run UV and Moonlight simultaneously. The OLED display shows the current level, lumens, battery level, and runtime information, and it indicates when UV is active. As displays in flashlights go, this one is genuinely useful.
Beam and Real-World Performance
Outdoors, the beam profile is more floody than the throw figure suggests, though it is not a flood light. The hotspot is fairly large with a cool white tone, and the outer perimeter is not especially wide, but it gets the job done for general use around a property. At 200 lumens it comfortably lights up a barn and trees at distance, and at higher levels the extra output is immediately noticeable.

Turbo is the caution zone. Packing 3,600 lumens into a body this small means there is nowhere for the heat to go. During use, Turbo caused the body to heat up quickly, reaching around 135 degrees, hot enough that sustained use really calls for gloves. Beyond about a minute at full output, it becomes uncomfortable to hold bare-handed. Turbo is best treated as a short-burst setting with the useful 1,200-lumen step-down doing the longer work.
Who This Flashlight Is For
Despite being marketed as a tactical everyday carry flashlight, the BL50 is better described as a specialized tool. The tail switch and strobe are the only genuinely tactical features, and the design leaves nowhere to mount a pocket clip, with no clip or holster included in the box. Carrying it means dropping it loose in a pocket or a backpack, which takes it out of serious everyday carry territory for most people.
What it is, is a flashlight for someone who specifically wants a high-output white light and a UV light in one package. The fairly bright 365nm UV mode is handy for checking counterfeit money and, for frequent hotel guests, inspecting a room. Whether you actually want to see what that UV reveals is a matter of personal temperament. If that dual light source combination plus 3,600 lumens matches your needs, this light makes a lot of sense.
Things to Consider Before Buying
The main drawbacks are worth stating plainly. Turbo heat buildup is significant, with no comfortable place for your hand during extended full-output use. The lack of a pocket clip or holster undermines the everyday carry positioning. And the 5-lumen Moonlight, while instantly accessible, is brighter than some would like for a low-light mode.

On the plus side, the aesthetics and grip are genuinely good, instant Moonlight access is a smart feature, 3,600 lumens in this body size is impressive, the OLED display is a real asset, and the price seals the deal: $69.95, under $70 for 3,600 lumens, IPX8 water protection, and a UV light. For what it offers, that is a strong value.
Buying Advice
If you want a pocketable everyday carry light with a clip, look elsewhere. If you want a compact, well-built flashlight that pairs serious white light output with a genuinely useful UV mode, and you can accept short Turbo bursts and backpack-style carry, the BL50 is one of the more distinctive options available, and at under $70 it is easy to justify.
Conclusion
The Imalent BL50 is a specialized flashlight that does its specific job very well: 3,600 lumens, a useful 365nm UV light, a great OLED display, and IPX8 durability in a comfortable compact body, all at a very fair price. Its weaknesses, Turbo heat and no carrying solution, only matter if you were expecting a true everyday carry or tactical light. Buy it for what it is, and it is hard to beat.
