A good flashlight is a necessity for everyone. Flashlights are a good choice for those who are looking for a solid handheld source of light. Advances in technology have brought about efficient flashlights that are lightweight, handy and small. It's easy to select the right LED flashlight. The following are things you have to consider when picking an LED flashlight.

​

The unit for measuring the brightness of light is lumens. The best flashlight needs to have brightness control features that enable you to regulate light intensity. The brightness settings function is also used to measure beam intensity, distance of light and its efficiency. The light output from most LED flashlights ranges from 20 lumens to 3500 lumens. Bright flashlights can be used in outdoor activities such as rock-climbing, caving, fishing, hunting, camping and hiking. Check out the Fenix Store to learn more.

Type of battery is a vital factor to think about when selecting a flashlight. AA, CR123A and AA are the most common batteries. The size of the flashlight determines the type of battery used. Pick a flashlight that's powered by small batteries. They're comfortable in your hand and lightweight. Some LED flashlights come with built-in lithium ion batteries. The best source of power for LED flashlights are Li-ion batteries. They're long-lasting and can be recharged. Therefore, your batteries will never run out. You can use a single lithium ion battery for about 400 times.

​

AAA and AA batteries are easily available in any store near you. They're inexpensive and convenient. However, their shelf-life isn't as long as that of lithium batteries. Although CR123A batteries are costly, they're durable. They're lighter, have greater energy storage capacity and give higher performance in cold environments. Disposable lithium batteries provide brighter light. Furthermore, they're not corrosive to the LED flashlight because they're unlikely to leak.

​

Your preference determines the flashlight's size and weight. You can carry lightweight and small flashlights in a bag, a pocket or on a keyring. Large flashlights can be stored in glove compartments, drawers and backpacks. The flashlight's size usually depends on the battery type, scope of application and the kind of beam.

​

One of the most important features to consider is functional capabilities. Some LED flashlight come with 4 or more brightness levels while others have just one brightness mode. In flashlights, you can regulate the brightness of light and the runtime. Consider how often you'll use the flashlight when picking one. These days, flashlights are fitted with programmable lights. This kind of flashlight can be great for you.

​

These tips will help you understand the kind of LED flashlight you should get. They're useful in determining the distance of illumination and the battery type to use. They also determine how bright the light should be.
