The Complete Buyers Guide – What You Need To Know
How is “Bright” Measured?
It may not seem like it makes much sense, but brightness is actually something that can be easily measured via a number of units. The most common ways to measure brightness are by lumens, lux, candela, or simply by brightness or luminance. However, we’ll be focusing on lumens, the most common means of measuring flashlight brightness.
In mathematical terms, one lumen is a measure of luminous flux. It is equal to one candela (light intensity) multiplied by one steradian (1/12.566 of a sphere). In layman’s terms, lumens simply measure the total light emitted by a particular source.
You can imagine it as such: envision that you are standing within a cardboard box that measures 1m2. If you were holding a candle within the box, one lumen would be the amount of light that falls onto the box, so the more candles you hold, the higher the lumens.
Light output can range from a minuscule 9 lumens all the way up to a blazing 3500 lumens. For a reasonably priced flashlight with a good amount of power and brightness, you’ll be looking for flashlights with brightness ratings of anywhere from 100 to 1000 lumens depending on what you want to use it for. The important part is that the flashlights live up to these promises.
Manufacturers often list lumens based on the ratings of the bare emitters or light sources of the flashlights, meaning that the flashlight itself will have a lower lumens rating than that.
However, companies that measure lumens out the front (OTF) will be listing the lumens ratings based on what you get out of the front of the flashlight; there will be a statement saying if it is measured this way on the packaging.
Types of Flashlights
There are two ways to classify the kinds of flashlights that there are. One way is by the type of bulbs or light outputs that they use, and the other is by their uses and what they are built for. We’ll take a look at each of them, one by one.
Types of Flashlights by Bulbs
LED Lights
LED stands for light-emitting diodes, which are a form of semiconductor. These tend to have long lives due to the fact that they are not made of glass or filament, and also thanks to their lack of energy wastage. Most bright flashlights at a reasonable price make use of white LED lights.
Incandescent Bulbs
These are the oldest and least expensive kind of flashlight in the book, as they’ve been around quite a while! They produce a lot of brightness but tend to waste energy due to heat production, resulting in batteries and bulbs that aren’t very durable.
HID Bulbs
Short for High Intensity Discharge bulbs, these function via an arranged ball of ionized gas that electric current then goes through. These tend to be heftier and more expensive, and as such, they aren’t as common – but they’re extremely bright and last long!
Pressurized Gas Bulbs
These bulbs may be filled with xenon, halogen, or krypton, as these gases can help to make the inner filaments have a longer lifespan. This, in turn, allows bulbs to burn brightly without wasting too much battery power. These tend to be some of the brightest bulbs, but they don’t last nearly as long as LEDs!
Shake Flashlights
These work by shaking the magnets within them, providing you with several hours of LED light that isn’t very bright, but is always at the ready! However, be careful with these powerful magnet lights – they may damage credit cards, computers, or pacemakers.
Types of Flashlights by Build
Common Utility Flashlights
These are the most basic, staple flashlights you could possibly ask for, and they are often the most inexpensive. They typically make use of a single incandescent bulb and are made mostly from plastic. They also tend to run on D-cells. These flashlights usually have weaker beams and a low durability rate, and they often run out of battery very quickly.
Heavy Duty Flashlights or Industrial Flashlights
Made from a heavy plastic or plastic composite, these are slightly better than the common utility flashlight. They have more durability but may still break easily and do not have very bright beams, often maxing out at around 18 lumens. They usually use incandescent bulbs or pressurized gas bulbs and are powered by D-cells.
Work Flashlights
These are made for everyday use and tend to be made of a stronger plastic and nylon composite in order to withstand the occasional beating. They may make use of pressurized gas bulbs and often max out at around 30 lumens. Their battery life and light brightness are often around average, and they may have some form of water resistance.
Tactical Flashlights
These are the types of lights you want if you want brightness. Tactical flashlights are designed for outdoor use and are made to withstand the elements, with high-grade elements built in and strongly durable outer bodies. These lights are often used in military, police, or rescue situations, and as such, they make great options for powerful flashlights.
They may use pressurized gas bulbs, halogen bulbs, HID bulbs, or LED bulbs and can run on a wide variety of batteries. They’re meant to last long and be blindingly bright.
Main Factors To Look For In A Flashlight
Light Pattern
This refers to how the light leaves a flashlight – is it a narrow beam, or a wide one, or perhaps somewhere in the middle? Some flashlights have an adjustable zoom function so that you can adjust the light patterns to suit your needs.
Color
White LED lights have become the norm for bright flashlights, and many find them to be natural. However, some find these lights to be too harsh and prefer yellow lighting. This is a matter of personal preference, so choose what works best for you.
Brightness
How bright is a flashlight? Mostly, this is measured by lumens (see number 4). Some flashlights also have adjustable brightness modes so that you can tailor how strong the beam of light is depending on your situation.
Lumens
This rating of brightness will give you a better idea of how heavily the light will fall on the environment around it. You can scroll back up to read more about lumens!
Beam distance
How far does a beam of light reach? Some go for up to 500 feet ahead, with a width of even five feet. Some claim to cover football fields. A farther range is generally thought to be more desirable as it provides better visibility. Flashlights with a zoom function may be able to adjust some aspects of their beam range.
Batteries
Different flashlights run on different batteries, and depending on what you prefer to use, it’s a good idea to know what type the flashlight you’re about to buy runs on. D-cells, AAs, AAAs, rechargeable 18650s, and Lithium-Ion batteries are all popular ones. Do some research about each one to find out more about them!
Battery Life
Once more: different flashlights run on different batteries, and each one has its own lifespan. It’s a good idea to note how long a flashlight can run on a particular battery before needing them replaced or charged.
Power Source
If not referring to batteries, this often points to the bulbs used by the flashlight. You can scroll back up to read more about each type of bulb!
Weather Resistance
If you plan to use a flashlight outdoors, then it will be a good idea to pick up one that has some form of water resistance. Some flashlights are also shockproof or vibration proof in order to withstand very harsh conditions – and being dropped during them. Even if you plan to only use a flashlight indoors, some weather resistance could be a great help.
Switch
How does the flashlight turn on and off or switch between modes? Is that method somewhat flimsy? Once a switch breaks, the flashlight is usually lost – so make sure you buy one with a durable switch.
Frequently Asked Questions
How do flashlights work?
Essentially, a flashlight is powered by batteries that create an electrical current. This current runs through metal contact points, bringing itself to the flashlight’s bulbs. Within these bulbs, there is a thin wire that contains an element known as tungsten, and this element glows when electricity comes into contact with it.
What can a flashlight be used for?
At the most basic level, flashlights are a great portable source of light that you can bring along with you. They’re mainly used for safety purposes, for a general house or work uses, or for outdoor activities. There’s rarely a limit for what you can use the light on your flashlight for!
How do you store a flashlight?
Flashlights should be easy to get to in the case of an emergency. They should be stored in a cool, dry place away from direct sunlight, and preferably away from water.
Can flashlight bulbs be replaced?
The short answer is yes. Almost all flashlights will allow for this. However, LED flashlights don’t need to have their bulbs replaced as they’re not meant to burn out.
Should batteries be removed when a flashlight is not in use?
It’s much safer to keep the batteries inside the flashlight so that it’s ready to operate in an emergency. If you’re concerned about the batteries running out, that you can simply keep a pack of unused batteries in the same place that you store the flashlight.
Operation and Maintenance Tips
In order to prolong the life of your flashlight, it’s a good idea to know how to properly operate and perform maintenance on it. This is to ensure that you have a light that will last you as long as possible. Here are some tips.
- Replacing flashlight bulbs periodically is a fantastic way to extend the life of your flashlight, and this is even more important if your flashlight is vital for missions or tactical situations. Once again, though, LEDs do not need to be replaced!
- Even if you barely use your flashlight, check in on it every once in a while just to switch the power on and off again. Don’t forget to check the batteries and switch them out every so often to ensure that no leakage happens that damages the flashlight. If you use your flashlight very frequently, then make sure to change the batteries when you see the light beginning to grow dim. This will prolong the life of the bulbs in the flashlight.
- Make sure that the switch on your flashlight does not become blocked. If you notice that a switch stops receiving an instant response, it may be time to change the flashlight altogether – you don’t want it to stop working when you need it most!
- Dirt and grime are an enemy for many electrical products, and flashlights are the same. Make sure to keep your light clean, so wipe them regularly with rags or a cotton swab. During the cleaning process, you’ll also be able to check for cracks and breakages, so you kill two birds with one stone.
- Even if a flashlight claims to be waterproof, refrain from completely submerging or placing the flashlight inside water, instead of keeping the water resistance to heavy rain and similar weather conditions.
Conclusion
Flashlights are an important object to have in every home, and they can be handy in a pinch and during emergencies. The brightest flashlight can be a real life-saver!
All these flashlights had fantastic brightness ratings and great features to offer, so take your pick, or look for one that better suits your needs.
We hope this guide has helped you out and that you will soon own a bright and powerful flashlight that will serve you for years to come!
