The best source of light during a power outage is any high-quality portable LED light source. LED flashlights use less energy than regular flashlights, which means longer battery life. They are also capable of being as bright or brighter than other bulbs while retaining their efficiency.
A flashlight is an essential item to include in an emergency kit because of how reliant we are on our eyes. If trapped in an emergency, it is vital to have the ability to see what is happening and how you can get yourself and others out of danger.
