If you are out in the wilderness, or stranded alongside the road in the middle of the night, the last thing you want is for your flashlight to flicker and die! Now you are stuck in the dark with no means of lighting your path or signaling for help…
This is why it is so important to take into account the run time of the tactical or emergency flashlight you are using.
LED life is how long the bulb or bulbs in your flashlight will last; it can vary from 30 minutes to many hours. Other than the quality of the batteries you are using, there are different factors that can impact the run time of your tactical flashlight.
Brightness Settings: It is possible to adjust the brightness of your tactical flashlight’s beam, but this depends on the flashlight. The highest setting will obviously drain the battery faster than the lowest, so always use the proper setting for the environment to preserve your batteries.
Batteries Used: Run time depends on what batteries you are using. Many tactical flashlights are compatible with different battery types, but some are more efficient than others. Changing the type of battery you are using will affect the run time in some way.
Temperature: This can also affect the run time of a tactical flashlight. Cold, heat and humidity can cause a battery to operate at less than its peak efficiency. This is definitely something to keep in mind if you are going to use your flashlight in extreme conditions.
