Factors to look for in the best 18650 flashlight

In order for a flashlight to last long, you need to select a durable one. Choose a lumen light that is both impact and water-resistant. On most occasions, you will be carrying the 18650 flashlight with you and it has a high chance of falling down. To avoid crashing or water getting into the LED flashlight, go for one created from aircraft-grade aluminum which is a strong metal.

  • Type of bulb

Not all bulbs will provide the same results. Pick a light source that uses LED bulbs as they have been discovered to be powerful, brighter, and last longer than the other types of batteries.

  • Lumens

The lumens determine how bright the flashlight will turn out to be. The higher the number of lumens the led flashlight has the brighter it will light. So, if you want a very bright light, pick a 18650 torch with lumens of at least 300 or above.

  • Run time

The run time means the periods that the flashlight will operate before it drops to 10 percent of the rated output. Almost every manufacturer lists a run time on the led flashlights. If you use the brighter modes more often, the battery will deplete quickly as the run time will be high when compared to using low light.

  • Size

Most of the 18650 flashlights are small in size and easy to carry. They can be placed in pockets or bags for safekeeping. Always select the EDC light that is portable and convenient for you when it comes to performing various duties. Check the weight and it shouldn’t be heavy to make you uncomfortable.

  • Beam distance

The distance the flashlight covers is known as beam distance. If it covers a long distance, then it is known as a spot beam, but it covers a wider area, then it can be referred to as a flood beam. Spot beam is great for hunting, fishing and hiking. While flood beam can be applied for walking, camping or for searching for a lost item.

  • Lighting modes

Consider acquiring an led flashlight with all the 5 lighting modes. This will give you an opportunity of controlling how the battery is run. These modes are: low, high, medium, strobe and SOS. The strobe mode is usually used to disorient enemies.  All these modes making using a lumen light to be fun.

  • Warranty

If you have ever bought a product and found it to have a defect, then you know the importance of having a warranty. Whether it’s one year or more than that, it’s worth it.

Also, a warranty will give you the confidence of using the flashlight knowing that it’s covered in case it has an issue you know nothing about.
