During my deep dive into the flashlight world, I discovered a relatively new brand AceBeam (est. 2014). The name kept showing up on forums and a friend mentioned they were excellent lights, so I had to try them out. They offer a wide variety of flashlights for any situation from diving to hunting and anything in between. Having so many everyday carry lights, I wanted to try out something different and go for a long-range thrower. AceBeam’s L-series of tactical throwers fits this bill and I decided to try out the L19.
The L19 is their latest model in the L series lineup and is designed specifically for long-range use. According to the specs, the white LED version has an incredible throw of 1,350 meters with a maximum brightness of 1,650 lumens. The L19 is also offered in green LED and for those running night vision, infrared.

What’s in the box
AceBeam includes a few nice accessories to go with the L19. Inside the box you’ll find the L19, a nylon belt holster with Velcro, a wrist lanyard, USB charging cable with power bank adapter, two spare o-rings, extra rubber switch cover, manual, warranty cards, and the AceBeam 21700 USB-C battery (battery does not come with all models). Surprisingly the accessories are all made from high quality materials. Most of the time, the flashlight holsters are a flimsy piece of nylon with bad stitching. But not this one. It’s thick, has reinforced seams, and quality stitching.
In the hand, the L19 has a nice balanced weight and quality feel to it. The aircraft grade aluminum body has a matte hard coat anodized finish and features a frag milling pattern that provides a pleasant grip surface. There are no gaps between the body and electronic switch, or tail cap. The machining quality is exceptional – all the surfaces are smooth and clean. It looks as if the light was constructed from a single piece of aluminum, you can’t even tell where the tail cap joins the body. One of my biggest pet peeves about flashlights are the rattles. I’m pleased to say the L19 doesn’t have any of those and is built solid.
The tail cap itself has a nice rubber boot covering the switch with the same frag pattern found on the body. It is a push to click activated tail switch and has a positive tactile feel. Just below the tail switch is an all-metal tactical ring with a cutout for the lanyard attachment. The metal activation switch on the main body is flush with the tube to prevent accidental use. Next to the switch is the battery indicator. It will change from green to red as the battery drains.
The L19 features a crenulated strike bezel that houses the TIR (total internal reflection) optic and LED. AceBeam used a domeless OSRAM LED that produces a very narrow, high intensity beam. Paired with the TIR optic, the L19 has a tightly focused beam with small but intense hotspot. Surprisingly there is very little spill. Which is to be expected with a long-range thrower.
Operating and Use
Unlike some other flashlights, the L19 has a very user-friendly interface. It has 6 different operating modes and a memory feature. The tail cap switch activates turbo mode only – half press for momentary on, and full press with click for continuous use.
Use the side switch on the body to cycle through the different light modes. Press it once to turn it on. Once on, press and hold to switch light modes. Once off, the light will turn back on to the last used setting. To activate moonlight mode, from the off position, press and hold the side switch. Turbo mode can be activated from off or during any mode with a double click. Strobe mode is activated with a triple click. The side switch can also be pressed and held for 5 seconds to lockout the light. Press and hold for 5 seconds to unlock. None of the lighting modes displayed flickering or PWM issues.
AceBeam’s 21700 protected button top battery has a built in USB-C charging port. Charging using the provided USB cable proved to be a bit slow and took around 4.5 hours to charge. However, the charging cable also has a USB A female adapter on one end so you can use the battery as a power bank to charge other devices in a pinch. The AceBeam 21700 is a bit longer than traditional 21700 batteries, but it still fits in my bank charger and my other protected 21700s worked just fine in the L19.
Turning on the L19 for the first time caught me by surprised. I wasn’t expecting the beam pattern to be so tight and focused with almost no spill. The color temperature appears to be a bright white around 5700K. Indoors, the L19 leaves a lot to be desired which is understandable since it’s a long-range illuminator. Outside is where we can see that tight beam stretching out as far as the eye can see.
The TIR optic used in the L19 does an incredible job at concentrating the light into a bright hotspot. Even on the moonlight setting of just 1 lumen, it’s still plenty bright to use on a walk. Most flashlights in moonlight mode are only good for reading a book just inches from your face.
I took the L19 out to the park down the street where I could shine out as far as 600 meters. In turbo mode, the beam looks like a white search light scanning the sky. It reminded me of the spotlights I used to see as a kid panning the sky at the movie theater down the street. Needless to say, it had me grinning and I could clearly see anything the beam touched. It easily illuminated the bayou 600 meters down to the highway where I could then see the cars glowing as they passed on the feeder road. The L19 is truly impressive, and I don’t doubt you could easily see 1,000+ meters when paired with a magnified optic.
AceBeam makes a picatinny rail mount and tail cap pressure switch for use on long guns. This would make for a great varmint hunting spotlight, and the green LED version would be ideal for predators. It’s light enough to use in hand for prolonged periods, and much lighter than my previous hunting light reducing the bulkiness on the gun.
The L19 is a winner if you’re looking to shine out to long distances. It does a great job at spotlighting targets 40 feet and further. It’d be ideal for people in search and rescue, law enforcement, property owners, hunters, and anyone who just appreciates high-powered flashlights.
There are no extra features to complicate the interface, and the light has performed flawlessly during my use. The one gripe I have about the L19 is that it does require the use of protected 21700 batteries. Not a big deal since battery technology has come a long way in recent years, but something I wanted to point out.
AceBeam has an excellent warranty program and from what others have said about their customer service, they are responsive and fast. The ability to spot targets as far as my eye can see, the compact size and high-quality manufacturing make the L19 my new favorite spotlight.
