Why choose this flashlight?
Lumens are a measure of the total visible light emitted by a source and are the current standard for measuring the power of flashlights and lightbulbs. Wattage used to be the standard, but this unit only represents energy use, and modern energy-efficient LED lights can generate a lot of light with minimal watts.
