This independent guide was created to help you understand the basics of flashlights and to help you choose the right flashlight for you. We do not sell any flashlights ourselves, so you can be confident that all of the information in this guide is independent and unbiased.

Background on flashlights
Flashlights are great products that help us see in environments where otherwise we would be fumbling in the dark. People use flashlights at work, at home, and at play; flashlights are used by law enforcement, outdoorsmen, and as emergency backup; the simple flashlight is one of the most useful products around. Flashlights are designed for one function- to provide light- and are basically simple and inexpensive products without a wide range of differences among brands and models. But, there are a few important features and functions to consider when finding the flashlight that's right for you, especially if you have not purchased a flashlight for a few years.

Developments in lighting and electronics technology over the last few years have led to the widespread availability and use of LEDs (light emitting diodes) as the light source for flashlights and other lighting equipment. Before to LEDs (and probably the case for most flashlights currently in your drawer or closet) flashlights used bulbs as the light source. Bulbs are relatively fragile, give off a relatively high amount of heat, and have a relatively short life. In contrast, LEDs are generally tiny light bulbs that fit into an electrical circuit and are illuminated solely by the movement of electrons in a semiconductor material. However, unlike ordinary flashlight bulbs, they are quite durable, they don't generate a significant amount of heat, and because there is no filament to burn out, they typically last for thousand of hours.

Features and functions of flashlights
Searching for a flashlight online is a great way to research and compare several types, models and brands of flashlights to make sure you find what that will work for you. Internet shopping can also be a lot more efficient than driving across and around town in person, especially if there is no store that sells flashlights close to you. Not only do online flashlight stores have a much larger selection than most retail stores that sell flashlights, but shopping online for flashlights is also more convenient because it can be done 24 hours a day.

To a large degree, the choice of flashlight you want or need will depend on how you intend to use the flashlight. Besides from whether or not you want to get a flashlight with a traditional bulb or with LEDs, there are a few other features to consider when finding the right flashlight for you:
