Flashlights Can Start a Fire: Is This Myth or Fact?


Are you planning to go on a campfire trip? Well, if you have a flashlight, you may wonder whether flashlights can start a fire. And Is that a myth or fact?

In fact, it depends. If all the right states are accessible, then powerful flashlights will start fires. For illustration, if a flashlight LED is in direct sunlight, the lens could act like a magnifying glass. Then it will concentrate the sun to ignite the fuel source.

In this article, we’ll illustrate what flashlight fires are exactly.

How Do Fires Ignite?

Any fire starts with the three essentials obligatory for ignition: heat, fuel, and oxygen. The combination of these factors generates an exothermic reaction. Then through this reaction, we will have a fire.


Fuel is any matter that can react with atmospheric oxygen. For illustration, it can be paper, gasoline, or any flammable solids.

Also, fuel can be in the form of gas such as propane, methane, or natural gas.


Oxygen is available in the air all around us. Without oxygen, we will not be able to have a fire. When the fuel and oxygen unite, it generates heat power.


Heat is the ignition source. Without heat, we cannot have a fire even if all other elements are accessible. We can get it from many things. Some of them are white light, halogen light, electricity, sparks, or even friction.

In other words, heat is the power that starts the reaction between fuel and oxygen. Then the temperature elevates until it gets to the flashpoint.

The flashpoint is the temperature degree at which the fuel vaporizes. Then it generates a self-sustaining ignition.

How Many Lumens Are Necessary to Start a Fire?

There’s no definitive reply to how many lumens are obligatory to start a fire. It leans on several factors. It includes the igniting material and the weather conditions.

Also, it includes aiming and light focus. Yet, we can make some presumptions depending on the available analysis.

For illustration, studies showed that light with a luminous intensity of 2300 lumens could ignite paper or wood.

Of course, this is just a starting phase. In fact, you will be more or less light depending on the specific environmental factors.

How Can I Make a Fire with a Bodied Flashlight?

First, you’ll need any matter that will catch fire, which can be anything from dry leaves and grass to thin bark strips or cotton balls. By the time you gather your fuel, build a small pile.

Next, break the glass of the lens cap off your handheld flashlight. Similarly, break the glass surrounding the bulb’s filament inside the flashlight. Once you’ve finished collecting the fuel, fill the top of the flashlight with it. Then turn on the flashlight.

Now, you should move the flashlight closer to the campfire you prepared ahead. Then, wait for a few seconds until the fire is transferred to the campfire.
