Keep all your doubts aside and read on to find the answer to the question, “why are flashlights called torches?”. Do they refer to the same thing or two different things?
Why Are Flashlights Called Torches?
People in the United States refer to a handheld electric light as a flashlight. Batteries usually power these. Some devices have battery compartments and charging ports to recharge after use.
Different types of flashlights are available depending on their purpose. Flashlights also come with options to adjust the brightness, beam, etc. More on the various kinds of flashlights later on.
Torch Or Flashlight?
You would have heard people using the word ‘torch.’ Have you ever wondered what it means? Is it the same as what you call a flashlight? Or is it a completely different device?
A flashlight and a torch are technically the same. A torch is what many British English-speaking countries call a flashlight. As you expected, the word came into use in Britain. Up to this day, Britons refer to flashlights as torches. More on the history of torches later on.
About Britain’s ‘Electric Torch’
Before the invention of the flashlight, the word ‘torch’ was popularly used to indicate a stick with a combustible material at the end, which can be lit and turned into a light source.
Excellent examples of torches that Americans describe are the one in the Statue of Liberty and the Olympic torch.
When torches were introduced, the Britons called these the ‘electric torch,’ referring to an electric version of the above burning stick. Later, the word ‘electric’ was dropped because of the decline in using the above-mentioned burning sticks.
A majority of countries that use British English call the flashlight the torch. However, Canada uses the term flashlight, although it is a British English-speaking country.
History Of The Torch
The National Carbon Company manufactured the first dry cell battery in 1896. It happened after German physician Carl Gassner invented it in 1888. The dry cell battery consists of an electrolyte in paste form instead of liquid.
The dry cell battery gave the advantage that it didn’t break or spill as quickly as its predecessor. Therefore, it was ideal as a portable light source. That is how the torch came about in 1899 when British inventor David Misell developed the first model.
The Americans called it a flashlight because it couldn’t provide constant currents for extended periods. It was due to the zinc-carbon batteries that powered flashlights initially.
So, they had to keep being turned off, which is synonymous with giving out flashes of light. The Russian inventor Conrad Hubert aptly named the device ‘flashlight.’
How Do Flashlights Work
In earlier flashlights, the bulb, the illumination source, was either a tungsten filament incandescent bulb. The flashlights that we see today commonly feature LED bulbs.
The power source that produces electrons is usually made through batteries, either rechargeable or disposable.
Flashlights with alkaline batteries are affordable and can last between four and ten hours. Flashlights with rechargeable batteries are powered by lithium-ion.
A basic flashlight consists of a bulb, reflector, and electric cells covered in a plastic case with a slide switch.

- Light output: The total amount of visible light that the flashlight produces is measured in lumens. The more lumens a flashlight produces, the brighter the light will be.
- Beam distance is how far the light can reach and is measured in meters.
- Run time: The time it takes for the light output to decrease to 10% of the rated output of new batteries. The run time of a flashlight is measured in hours.
- Water resistance: It is rated using the IPX system and is useful when using the flashlight in the rain or around bodies of water.
- Impact resistance: Measured in meters, it is when lights are tested by dropping them six times onto concrete at a given distance. It ensures that the flashlight will work even after accidental drops.
How Do You Power A Flashlight?
Here are a few common ways in which you can power a flashlight.
- Battery-powered: Handy device due to its portability.
- Solar charging: Ideal to use in remote areas where there is no power.
