Choosing A Keychain Flashlight

LED Bulbs

As mentioned above, keychain flashlights may be small, but their bulbs are powerful enough to emit a bright light. Another good thing about LED is that they don’t use a lot of energy unlike any other bulbs today. Even if your LED bulb is installed in a keychain flashlight, I can assure you that the bulb can long for an extended period of time because it is efficient and strong. Typically, a LED can measure from 9 lumens, and if the flashlight contains a Cree Cp-G2 S3 high performance, then it can provide you with 180 to 360 lumens.

Always remembers that the bulb’s quality can help determine its brightness and as well as the distance that it can reach. There are keychain flashlights that can reach 80 yards, but there are also some that can reach a mile.

Type Of Beam

For people who don’t know, a keychain flashlight is known to be projected either as a floodlight beam or a spot beam. The spot beam can help you see things in a small area but over a long distance. You have the option to use this type of flashlight along the tracks in the forest. A floodlight, on the other hand, can help you with a broader area since it projects a cone she light. This is ideal when it comes to working outdoors or when doing DIY home project, walking the dog, or even when you are working on your car.

Life Of Battery

Of course, the life of the battery is also important when purchasing a keychain flashlight. Always put in mind that the longer the life, the better the runtime. There is some keychain flashlight that comes with triple-A batteries that are disposable. Some are using the alkaline battery, which can provide you with 8 hours of battery life. Of course, there are also keychain flashlights with batteries that are rechargeable.

Brightness Settings

There are keychain flashlights that will let you adjust the brightness level from high, medium, to low. This is actually a useful feature since you can save a lot of power by using the medium and the low setting when needed. It also gives you full control over the brightness that you would want for your flashlight. But put in mind that when you set the flashlight to its brightest setting, the chances of running out of battery fast is possible. So if you don’t need it, then just lower down the brightness.
