Quicklist: Types of Flashlights
- Incandescent Bulb
- Light Emitting Diode (LED)
- High-Intensity Discharge (HID)
- Pressurized Gas
When were flashlights invented?
The first flashlight was invented in 1899 by English inventor David Misell. It was called “flash” light because the light couldn’t be turned on for long and had to be rested from time to time. That’s because it used zinc-carbon batteries and carbon-filament electric bulbs.
The batteries were eventually improved and the carbon filament was replaced with tungsten. By 1922, flashlights were a hit. Several types of flashlights existed as well as 10 million flashlight users.

Different Types of Flashlights (List)
Incandescent Bulb Flashlights
Incandescent bulb flashlights are the most common type found in people’s homes. They have been around for many decades and usually run on D batteries.
Generally speaking, these flashlights are most convenient for their affordability.
Incandescent bulb flashlights are made to be weather resistant and will resist corrosion as well. You will be able to make use of this flashlight in rainy situations because it is water resistant, and it is durable enough to withstand being dropped. It should work well for many purposes.
Popular on camping trips, due to their ease of use, they can withstand a bit of punishment and are powerful enough to provide light when needed.
There are situations where having an LED flashlight is going to be preferable. They don’t work in the same way as incandescent bulb flashlights – they don’t produce any heat and can last for a long time.
The cost of an LED flashlight should be similar to the cost of a heavy duty incandescent bulb flashlight.
LED flashlights give off a different type of light: Incandescent bulbs beam a white light with a yellow hue; LED lights give off white light with a blue hue.
High-Intensity Discharge HID Flashlights
High-intensity discharge flashlights are usually abbreviated to HID flashlights. These types of flashlights will be capable of producing an extremely bright light. They work by having an electrical current run through a ball of ionized gas, so they’re definitely different from either of the models that have been mentioned so far.
These flashlights are far less common than either incandescent models or LED models. The HID flashlights are more expensive due to how they work. In order to purchase one of these flashlights, you may have to pay up to 10 times the price of one of the incandescent flashlights.
The HID flashlight, shown here, is rechargeable and waterproof.
Pressurized Gas Flashlights
Some incandescent bulbs also include pressurized gases to increase the life of the bulb. Gases such as xenon, halogen, and krypton can help to brighten light while burning out more slowly.
The flashlight, shown here, comes equipped with a krypton bulb. This will allow the flashlight to generally be brighter while lasting longer. Despite its utility, this flashlight is also very inexpensive, making it a good option for anyone who is on a budget.
This flashlight is powered by standard D batteries, not unlike the vast majority of incandescent bulb flashlights, and are a good choice to have in emergency situations.
It’s no secret that environmental concerns have started to change the way that people look at the world. We need more environmentally-friendly options when purchasing tools. Flashlights are no exception and there are solar-powered options out there for people who wish to go that route. They can actually be pretty convenient to use and are powerful enough for many purposes.
Most solar-powered flashlights are going to be significantly weaker than the other options on this list. There are some models out there that can get fairly bright, but you shouldn’t expect it to be able to compete with an LED flashlight or an HID flashlight. These are cost-effective flashlights that will be comparable to an incandescent bulb flashlight when they are properly charged.
The model that is being shown here also comes with a hand crank. This allows you to generate some power on your own in order to produce light. This is convenient for when you haven’t charged the flashlight with solar energy and still need to make use of it.
Headlamp flashlights are very convenient to own because they can help you to light your way while your hands are otherwise occupied. If you need a flashlight to see, but you also need to carry something, it can get a little inconvenient. The solution to this problem is to own one of these headlamps.

You can see that there are many situations where a flashlight such as this one would come in handy.

With a brightness level of up to 1,800 lumens, this thing can really provide you with a significant amount of light. It’s a good purchase for anyone who wants an easy to use an emergency flashlight. The price is reasonable and it is very useful to own.
Lanterns are another convenient way to light up the area that you will want to consider. Of course, traditional lanterns use kerosene or another type of fuel to provide a flame. In modern times, LED lanterns have become much more common. They work similarly to LED flashlights, except you just need to set them down near your location, rather than pointing them where you want to go.
You can carry lanterns such as this to light your way, though. They’re just more commonly used for camping purposes than they are for hiking or walking somewhere in the dark. This lantern will work very nicely if you need to be able to see when the power goes out. People buy lanterns such as this all of the time just to be prepared for big storms.

If you want to purchase something that is simple to use and will be effective in an emergency, then this is a good item to buy. There isn’t a lot that sets this item apart from other lanterns, but it is reliable and cost effective.
Shake flashlights are sort of unique in that they don’t run on batteries. You might be curious how the flashlight would even work without a power source. It’s actually powered by magnets that are placed inside of the flashlight itself. When you shake the flashlight, it causes a reaction and will provide you with the light that you need.
You simply need to shake the flashlight whenever you need to use it. This is very convenient as you will not have to worry about buying batteries for your flashlight.

Heavy-duty flashlights are a bit better than the normal utility flashlights. These are built to last and will be able to take a bit of a beating. Dropping a flashlight such as this won’t really cause it much harm and it should be able to keep going. People take these flashlights with them on trips and even use them when they go out hunting.

Frequently Asked Questions
What are the brightest flashlights?
Just like any other technology, flashlights continue to evolve with how bright they can be. Measured in lumens, which is a unit of measurement for the amount of light emitted, the brightest flashlight today can shine at around 100,000 lumens. Currently, the MS18 Flashlight is recognized as the brightest flashlight available on the market in 2022, with an asking price of around $650.
Can you bring flashlights on a plane?
According to TSA.gov, you are allowed to bring a flashlight in your carry-on and checked baggage. However, it must be placed in your checked baggage and it typically needs to be seven inches or less. It may also be up to the discretion of the TSA officer if you have a tactical flashlight because they often look like weapons. The general consensus is that everyday flashlights under seven inches should be OK to bring aboard a plane.
What flashlights do police use?
Police officers typically use flashlights that are at least 1,000 lumens. They need to be able to see in low-light conditions, but they also need a flashlight that can blind an attacker if necessary. They also consider other factors, such as the battery, which needs to be able to last a long shift and easily replaceable. They also consider the size, which needs to be small enough to fit in a pocket, but bright enough to do the job.
Why do flashlights have strobe lights?
Strobe lights on flashlights are beneficial for several reasons. One of them is that it can be used as a form of self-defense. When shone in the eyes of an attacker, it can disorient and momentarily blind them, giving you time to escape. It can also be used as a signal for help, whether you are lost in the woods or stranded on the side of the road.
Do LED flashlights last longer?
LED flashlights last longer than your typical flashlight because they are more energy-efficient. They also don’t produce as much heat, which can cause damage to the bulb over time. You can typically expect an LED flashlight to last at least 50,000 hours, with some lasting up to 100,000 hours. In comparison, incandescent bulbs may only last roughly 2,000 hours.
Do flashlights work in space?
In case you’re deciding on a trip to outer space, you’ll want to know that flashlights work just fine in space. However, since there is no air in space, the light from the flashlight will just keep going until it eventually hits something. Outer space is a vacuum, so the light doesn’t have anything to bounce off of like it does on Earth.
Will flashlights work underwater?
The answer here depends on the type of flashlight you buy. Standard flashlights will not work underwater because they are not waterproof. However, there are dive lights and waterproof flashlights that are made to be used underwater. These special flashlights use a sealed O-ring to prevent water from getting in and damaging the light.
