When choosing a flashlight, first and foremost think about what you need out of it. Those who need a flashlight for hiking or hunting have different needs than those who simply need a flashlight to keep around the home. Having a flashlight with different modes, such a a strobe or SOS feature, can be important in these situations, as they can get you the help you need if an emergency were to occur. A flashlight with an SOS feature can also be a great option to keep in your car, as it can get you help if you are stranded on the road.
Today, many flashlights do not need traditional batteries and instead rely on rechargeable batteries. It is typically up to the buyer to decide which option is right for them. Those who use their flashlight often and who have regular access to a place to charge their flashlight might opt for a rechargeable option, while those who want a flashlight for emergencies may opt for one with traditional batteries so that they do not have to worry about charging.
