Besides the more common LED bulb lights that come with tactical flashlights-there are also incandescent options available. Much as incandescent bulbs are replaceable and give off better colors, a number of manufacturers tend to produce flashlights with LED bulbs since they tend to be shock proof and have a better lifespan as compared to the incandescent ones. There are numerous lumens of light to consider while buying a flashlight- from 1 lumen to over 700 lumens.
The choice is yours in determining how much light you wish your flashlight to have; however below we shall have a look at the different lumens and how they might affect your flashlight usage.
When we talk of lumens, we mean the measure of luminous flux which is the total amount of power or light energy that comes out of the face of the flashlight. This means that the higher the lumens, the powerful the light coming out of the flashlight. This does not however mean that great tactical flashlights should have high lumens-there are other things to take into consideration such as the reflector and distance in which the light shines.
Let’s have a look at the different lumens and how they might affect the use of tactical flashlights:
- Flashlights with 1-14 lumens are meant to be used in times when very limited light will do.
- Flashlights with 15-59 lumens will let you only see your immediate surroundings however; there is no enough brightness to temporarily blind the enemy.
- Flashlights with 60-149 lumens have just enough light to help you see things outdoor. In other words it is great for those walking in the night and need some bit of light to shine their path.
- Flashlights with 150-299 lumens not only light up a large room but can cause temporary blindness.
- Flashlights with 300-699 lumens make use of specialty batteries and can be compared to nearly lighting up the entire football field.
- Flashlights with 700+ lumens are for those who need maximum light while at the same time maintain a small handheld light. They are normally used by search and rescue teams.
Besides Lumens, the amount of light needed in a flashlight can also be determined by Candela and Beam distance. With Candela you are looking at the brightest point of light produced while with Beam distance you are looking at the distance in meters in which light can go till it reaches 0.25 lux(the amount of light output given off by a full moon on a clear night.
High peaks of brightness (candela) can be achieved by the beam angle. That is the smaller the beam angle the greater the peak brightness. As for the beam distance, the two things come into play-the reflector and the type of LED.… Read the rest
