One of the most important things to look for in a flashlight is brightness. In most cases, you want the brightest flashlight for your budget, don’t you? However, brightness varies greatly by the type and size of a flashlight. Today, LED lights are very common that can be quite bright, but there are other options as well. If you are looking for the brightest flashlight, the first feature to look into is lumens.


What is Brightness?

Brightness represents the intensity of light. Here are the important factors to look into when brightness is your preference.

  • Lumens: In a flashlight, brightness is measured in lumens, or the light it offers. A lumen refers to a unit of light. In most cases, it is the measure of the highest brightness output offered by the flashlight.

For example, if the flashlight says 800 lumens, this means, this is the highest brightness it offers. In most flashlights, you can find options to lower the brightness to make it more multi-purpose.

Generally, the more amount of lumens your flashlight has, the brighter the light would be. Any flashlight with a brightness of 500 lumens or more qualifies as highly bright. Anything over 1000 is considered as ultra-bright.

Lumens can also be calculated corresponding with the watts. For instance, an LED light of 9 to 13 Watts would emit a brightness of 1100 lumens. There is another term you should be familiar with: Candela. Candela is the unit used to measure the intensity of the beam.

  • Beam Distance: Lumens is not the only thing that makes your flashlight brightest, you also need to look into the beam distance, or how far the light can travel. The beam distance is the distance that the light covers until it diminishes to the level of full moon brightness.
  • Run Time: Another aspect of brightness you should keep in mind is the runtime. Obviously, higher brightness uses up more power so the runtime of the flashlight would reduce. In most cases, you would be able to keep it ON longer at low brightness. This is why if you are buying a highly bright flashlight, make sure to double check its battery’s runtime.


Why Brightness is Important When Buying Flashlights?

Brightness is, of course, one of the most important things to consider when buying a flashlight. Brightness directly depends on your flashlight needs. If you just want a flashlight to keep in your house or perhaps take on camping, you can do with average brightness (around 500 lumens). However, if you are a cop or rescue worker, you need the brightest and most reliable flashlight.

What to Look for in a Brightest Flashlight?

When buying a flashlight, brightness is not the only thing you should look for. There are other things to consider as well that will ensure that you get the bang for your buck. Here is what you should look for in a flashlight:

Type of Batteries: There are many different kinds of batteries, some more powerful than others. You can recharge some as well which is much more convenient and economical. In flashlights, you will most commonly find AA, AAA, and Li-ion batteries.

The more powerful the battery is, the higher the runtime of flashlight even with high brightness.

Flashlight Bulbs: While LEDs are more common nowadays, there are several types of bulbs including incandescent and High-Intensity Discharge (HID).

Beam Type: This is how the flashlight disperses the light. These include flood or fixed, that offers a single beam width. The second option is a spot or focused beam, that penetrates to a long distance in the form of a condensed, single beam. Most modern flashlights also allow you to adjust light beam from wide to focused.

Design and Weight: The design should meet your purpose. Ideally, it should be lightweight. A heavy flashlight is only going to make it difficult to use it.

Ergonomics: It should be comfortable to hold for hours and have a strong grip so that you do not drop it.

Water-resistance: Another thing to consider is water-resistance, especially if you are going to use the flashlight under rainy conditions. You need to look into IPX system ratings to check on the water-resistance of the flashlight.

IPX 4 means you can use it in rain, but not under water. IPX7 and IPX8 are both submersion ratings, which means you can use the flashlight underwater. For IPX7, it will work for half an hour, while for IPX8, it will work for four hours.
