Acebeam L18 Search Light

1,500 Lumens

The new Acebeam L18 is the newest edition in their Long Range series of search lights. The L18 is equipped with a high performance Osram LED and TIR optic lens system, enabling this light to put out 1,500 lumens and light up the night up to 1,000 meters away. With six brightness settings (plus strobe) and a soft, balanced beam, this light is perfect for a wide variety of applications and users.

Tactical Capabilities

The L18 was designed for tactical, hunting, search and outdoor use. It has a body diameter of 1" so it is compatible with most weapon mounts. The side switch is for an everyday activation and the tail switch can be used for tactical purposes or remote pressure switch attachment.

Intelligent Design

Powered by a single high capacity 21700 battery, the L18 has impressive run times and outputs. To keep the flashlight and battery protected, it has a constant current and temperature regulation system. This ensures a steady beam of light and prevents overheating during extended use.

Excellent quality light with incredible throw!
March 18, 2021
This is an excellent tactical or utility light that reaches farther than other lights in its class, with no competition at its price point. I know of almost no other light with this long-range performance, short of white laser lights at several times the price of the L18. It offers durability, high performance, extreme reach, versatile output options, and good runtimes, all in a surprisingly compact package. This light makes most other long-range lights obsolete.

The very tight beam is achieved using an OSRAM LED combined with a special TIR optical lens technology, with several concentric reflector rings that work similar to a fresnel lens to concentrate the beam, leaving very little spill. I have found the L18 to be useful at distances approaching a half-mile, yet at lower levels, it is also useful even up close in a dark room.

With a side switch that allows access to all levels, and a tail switch that gives instant access to turbo power, it is a very useful light for anyone who needs to see far at night while also providing defensive options along with a low level close range capability.

Its small size conceals its very large capacity 21700 lithium battery (which must be purchased separately). You can choose any 21700 from many available capacities and charging options. I prefer the ACEBEAM-IMR21700NP-510A-USB. You could also use 18650 or 2x CR123 (with a reduction in performance) using an adapter sleeve such as the FENIX-ALF-18. All of these items are available from our friends here at Battery Junction. The multi-fuel capability insures that you will be able to keep this light running in circumstances where other lights would be down for a recharge or battery replacement. Another nice feature is the power indicator light which keeps you informed of the remaining charge level of the battery.

All things considered, this is an excellent tool for anyone who needs to see a long way in the dark, while still maintaining a close-up option. BEWARE: Once you use a light such as this one, most other lights seem to be less capable, or even dim in comparison. It has certainly helped me thin out the lights that I consider necessary for my normal needs.

Buy this light, and put most of your other lights into reserve use. The only regret that you will have is that you bought all of those other lights before you found this one.

Great flashlight!

When i received this flashlight i was very surprised at how nice and sturdy it was. It was very well made with some weight to it and you can tell it's going to last forever.
The light itself is incredibly bright on all setting. I would recommend this product to everyone who needs a great light.
