Before You Buy

One of the hardest things about buying a flashlight is the sheer number of flashlight available to choose from. With hundreds of choices, it can be almost impossible to figure out if you are picking the right one. What can make it even harder is if you have never bought a flashlight before. 

Before you buy any flashlight you need to think about the primary use of the flashlight. You also need to consider overall brightness. How bright the light needs to be will depend on what your plan to use the light for. For example, if you need a light for camping trips you want something bright enough to search the darkness in front of you. You also need something low enough to preserve your night vision. In addition to how bright a light is you will want to consider what style of batteries it uses, how easy it is to operate, and what other features and benefits it provides.
