Best High-Power Flashlight

by Linea Lorenzo

When you find yourself in the middle of nowhere and it's pitch black outside, having a source of light you can flick on whenever you need to is a very important asset indeed.

Heck, even if you're not out camping, but in your own home instead and there's a blackout, having a flashlight handy means you can see where you're going and you can tackle whatever problem you encounter along the way.

Now, flashlights come in all possible and impossible shapes and sizes nowadays, so if you want to buy one of these contraptions, it's important you figure out what exactly you need it for. It doesn't make much sense spending too much money on a mighty flashlight if you only need it to have a backup light source in case there's a blackout in your house. ( For these cases, simple flashlights with a strong battery and perhaps a couple of backup batteries would do the trick just fine. )

At the same time, if you're an avid outdoors person and you often go on camping trips, having a flashlight that you can use when it's pitch dark outside can be a lifesaver. So, it makes sense to invest your hard-earned money this way.

Editor's Recommendation: Top Highpower Flashlights

In this article, we're going to talk about a special breed of flashlights you can use for a wide variety of outdoor situations - the high-power flashlights. These contraptions are way more powerful than just your regular flashlight and they usually come with powerful batteries that can run for longer than the ones installed in ordinary models.

To help you pick the best model for your needs, we've organized a list of the five best high-power flashlight models currently on the market. Also, we've prepared a brief buyer's guide, and we've ventured to answer some of the most frequently asked questions in this particular category. As you will see, finding the perfect flashlight model for your needs is not that tough as long as you know what you need it for.

Without further ado, here's the deal.

Lumens Rating

A flashlight's power is measured by how many lumens it can exert, so to speak.

High-power flashlights come in all shapes and sizes, but most have a lower power limit of about 2,500 lumens, while the higher end goes up to 6,000 lumens or more. Some of the most powerful models on the market can give you as many as 100,000 lumens, which is enough to light up an entire football stadium. ( If you're at an appropriate vantage point, let's say. )

Of course, we should also say that the more lumens you're using, the more quickly your flashlight battery will discharge, so you should aim not to use your flashlight at its highest setting if you don't have to.


Speaking of the devil, the runtime of a high-power flashlight depends on the two aforementioned values - the lumens rating, and the battery power.

Typically, many high-power flashlight batteries can last about 20 hours on a single charge, provided you use the flashlight at one of its lower settings. ( Let's say about 2,500 lumens. )

If you use the thing on higher settings, the battery life goes down. For example, a battery that can last 25 hours on low settings of 2,500 lumens will give you only about 8 hours of runtime on a higher setting at 6,000 lumens.


Although most high-power flashlights typically aren't designed to be used underwater, many manufacturers decide to make their flashlights waterproof.

The reason behind this is that while not many people will think of using their flashlights underwater, the flashlight can still end up in water through an accident. Since many folks use these contraptions when they go out hiking or fishing, the environments they're in often contain plenty of moisture and water, which can lead to the flashlight getting damaged if it's not properly protected.

So, if you plan to use your flashlight somewhere near water, make sure to get a model that is waterproof to ensure it won't break down if you drop it in.

Charging Adapters

When it comes to charging up a high-power flashlight, it can often be done in several different ways.

The thing is, since folks who use these apparatuses often drive and go outdoors on camping trips or hiking expeditions, for example, many flashlight makers opt to make it possible for their flashlights to be recharged by both an AC adapter and a DC one. So, if you're in a car, you won't need a converter to charge up your flashlight if it supports DC charging.

An important note: Many flashlight manufacturers don't include special adapters or chargers in the package when they're selling it, but only a USB cable. So, if this is the case with the model you're considering to buy, you'll have to buy a charging adapter separately.


The choice of material is an important one for makes of high-power flashlights.

The thing is, the material used for the housing needs to strike a fine balance between durability and weight, as the flashlight cannot be too heavy to carry around, but not too flimsy that it can break apart the first time you drop it on the ground - which tends to happen a lot when you're outdoors.

So, flashlight bodies, so to speak, are typically made out of some sort of aluminum alloy that can withstand the stress of falling to the ground and that is at the same time lightweight enough for you to carry around.

Frequently Asked Questions:

1. What is the most powerful LED flashlight?

Currently, one of the most powerful high-power flashlight models on the market would be the IMALENT MS18 flashlight.

This thing is capable of producing 100,000 lumens, which is a figure way above the other models on the market. What's more, this thing is so powerful that it has its cooling system which is there to prevent overheating when you're using the flashlight on its highest setting.

2. What flashlights do police use?

That depends on what country you're talking about.

In many Western countries, the police use small but powerful flashlights such as the model Streamlight Stinger DS LED HL or its cousin model Streamlight Strion DS HL. These flashlights can provide an excellent stream of light both outdoors and especially indoors, which is important for the police officers when they're conducting searches in poorly lit areas or during the night.

3. How many lumens does a police flashlight have?

While some special operation units may have powerful flashlights for special uses, most common police units use flashlights that don't typically have more than 400 lumens.

This may not seem like much, but it's just enough for what they need to do, as the parameters such as battery longevity and the reliability of the flashlights are more important factors than the overall lumens output.

4. How many lumens will temporarily blind someone?

For purposes of deterring an attacker, for example, about 300 lumens will be more than enough to temporarily blind someone.

Of course, any value higher than that will also work well and probably better, but you don't need more than 300 if all you want is to only temporarily blind someone.

5. How many lumens should a weapon light be?

This value would depend on the circumstances.

For example, if you're in a dark room with a white wall that can reflect light well, even 100 lumens will do the job of blinding someone temporarily.

In other settings where the light can't be reflected as well, you may need more than that for the blinding to work. In woods, for example, about 500 lumens would be required to blind someone temporarily.


All in all, if you're into fishing, hiking, camping, or you simply want to have a backup plan in terms of lighting in case your house runs out of power - getting a high-power flashlight can be a smart investment. We hope this article helped you learn more about some of the most powerful flashlights out there on the market, and we wish you a merry and hassle-free purchase.
