Keychain Flashlight Buying Guide

Before you make any purchase, you would want to be sure that it suits your requirements. While some people might want better durability, others might want more light input. When you set forth buying a keychain flashlight, you must consider the following things.

Lumens

The very first thing that is crucial to consider while flashlight shopping is to know the brightness you will get. Brightness is measured through lumens, and the amount of brightness you get is crucial to see what kind of purpose the flashlight can serve. 

While most keychain flashlights range to a brightness output of about 150, some can go up to 1000 lumens, which is insanely bright for a small product. 

Reflectors

Reflectors influence the beam style of a flashlight, which is one of the defining features of how good a flashlight is. A reflector is a metallic, shiny cone that surrounds the bulb to reflect the light produced through the flashlight.

If the reflector is smooth, the flashlight’s beam is generally focused and clean. Orange peel reflectors produce a smooth beam that is more spread out than usual.

Battery Rechargeability

Recharging a battery costs much less than buying a new one every time the battery in the flashlight drains out. Recharging is also more accessible than replacing batteries.

Some people, however, prefer to change batteries since rechargeable batteries tend to weaken over time. Recharging a battery is also more time consuming than simply replacing one, especially if you keep a reserve battery in your house.

Most people prefer smooth reflectors since they are great for long-distance spot beam. However, orange peel reflectors are preferable in keychain flashlights since most users of these flashlights are concerned with wider area illumination. 

The choice that you make depends on personal preference. If you like to replace batteries, but a flashlight that runs on AA or AAA batteries. Otherwise, opt for lithium-ion or li-po battery-powered flashlights.

Summing Up

Buying a keychain flashlight seems to be one of the easiest things to do. However, there is a lot of thought that can go into this purchase a well. This is because you would want to own a keychain flashlight that is not only powerful but also sticks with you for a long time. Through the buying guide in this article and the product list, you should be able to choose the product that will help you in need.
