How to Determine the Longest Throw Flashlight

Some people look for throwing distance when buying a flashlight. However, it’s not easy to determine whether the unit covers enough range for your personal needs. Apart from the standard factory declarations, there are a few ways you can use to find out how far your flashlight can go.

- The Lens

The depth and size of the reflector play a major role in the equation. The bigger the reflector, the longer the throw, it’s as simple as that. The reflector is what turns the lumens into a powerful light beam. Therefore, the better the reflector lens, the farther your flashlight will throw.

-  Lumens

Although it’s not the most important factor, the number of lumens does affect the throw range. There is no use in having a premium lens without adequate power. Optics has greatly improved over the last couple of years to the point where a single light beam can reach up to a few hundred feet of distance.

- The Beam Type

A lot of tactical flashlights offer different beam types which can be changed by twisting the lens in the right direction. As you might assume, focused beams have a better throwing distance; therefore, widespread beams tend to have a shorter cast and less brightness.

- The Power Source

Although many people think that batteries don’t affect the beam distance, it’s a wrong assumption. However, it might not be a significant role, but it’s still worth mentioning. The concept is pretty simple – the stronger the battery, the brighter the beam. Furthermore, the brighter the beam, the farther it will throw. The Li-Ion batteries are considered as one of the best choices.

- The Bulb Type

LED bulbs are the right choice. There are two other possible options which are Xenon and incandescent. Needless to say, incandescent bulbs aren’t a part of the equation whatsoever, due to the lack of lumens they emit. However, it’s a tight race between Xenon and LED bulbs. The bad thing about Xenon bulbs is that they are quite hard to find and are pretty expensive.

The Conclusion


Apart from reading the declared distance by the manufacturer, you can use some of these tips to determine how far that particular model will throw. If you apply the acquired knowledge, you shouldn’t have a problem with finding the longest throwing flashlight on the market.

Whether you need it for professional or home use, it’s always better to find something that suits your needs. Contrary to popular belief, you don’t always need the brightest unit you can find. Instead, try to fine-tune your requirements, and you will be able to pinpoint exactly what you need.
