Alittle over a thousand meters in distance but the runtimes are quite impressive as well and this light being its very affordable price was the biggest shock to myself.

250000 candela I have a lot of LED Flashlights Buy high end ones like surefire and Nitecore to name a few The Acebeam L18 is the one I like the best the throw is very uniform and not spill like other ones Because of the TIR this is a searchlight and a weapon light too I am glad to have bought this one was not disappointed

YOU MUST BUY ONE

Perfect light for people needing a thrower. Many times at work I need to illuminate far away objects while being able to carry it conveniently and without bulk. This fits my needs perfectly.

Long runtime also with the 21700.

I love the fit and finish of this light. The feel is practically soft, but still perfectly grippy. The LED was centered well, and throws well beyond the Eagtac G25C2 that I was replacing. Thisis my first 21700 light, and I ordered a Nitecore charger so I could keep a charged spare on hand.

The UI is very intuitive, but the only thing I'd prefer is for the rear button to be recessed within the end, instead of protruding, which could cause accidental engagement, and also prevents tailstanding.

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.
