How to Measure Brightness

Different brands across the world are trying to standardize the measurement of brightness by creating a standard called ANSI FL1. This enables there to be a unit that everybody can use for flashlights and other light sources and know quickly just what a product is capable of.

There are a couple ways that the ANSI measures light performance. One way is through the beam distance. The distance is defined as the distance that the beam will travel before hitting the brightness of the full moon on a clear night which is .25lux.

Another way that it is measured is through measuring the light output in lumens after the flashlight has been turned on for over 30 seconds.

The last way is through measuring the peak beam intensity. This takes the brightest part of the beam and measures it in candela or CD.

Something else that isn’t about light but is still a part of the ANSI FL1 is runtime. This is defined as the amount of minutes that the light can run before the light output goes below 10% of the original brightness.

Batteries and Brightness

Overall there are a few different types of batteries that are used in flashlights these days.

One is the classic AA and AAA batteries that you surely know about. They are so widely used because they are cheap and sold everywhere. There are even rechargeable types available.

The problem with these traditional types of batteries is that they typically don’t last all that long and don’t produce as much power as other types.

Another type of battery is the CR123A lithium cells that are commonly found in electronics such as cameras. They are smaller than AA batteries but were designed to be powerful. You can get both rechargeable and non rechargeable versions of these.

The last type of battery that I will go over here is the 18650 rechargeable lithium ion battery. This battery is very popular due to it’s low memory effect, strong ability to hold charge and it’s energy density. What is meant by memory effect is when a battery is charged many times it tends to lose it’s maximum storage capacity.

Battery Life

Many people think that battery life is only about convenience, but in reality there’s a huge safety compontent involved for some people. Anybody from law enforcement, to security, to people that like to go out at night could potentially be saved by having a strong flashlight.

One of the brightest LED flashlights can make a good deterrent for women in self defence situations. A potential attacker is much less likely to proceed if the area around is lit up. Also the flashlight itself can be used as a weapon in self defence situations.

So what affects battery life? Well the main factors are age, temperature, the battery type and build, as well as where it’s stored.

One thing that most batteries have in common is that they will be much better used with an LED than with an incandescent bulb, this is why I’ve reviewed all LED flashlights in this article.

Alkaline batteries don’t last as long as lithium ones do. Lithium ones tend to last around 10 years typically, while alkaline ones have a life of around 5 years.

If you want to extend the battery life of your LED flashlight then the best way to do that is to use it on the dimmest mode if possible. This will extend the life by a TON.

That wraps up my reviews of the brightest LED flashlights. If you want to see some other options but don’t need anything super bright then check out my tactical flashlight reviews for some more general options.
