What Makes a Good LED Flashlight

WHAT MAKES A GOOD LED FLASHLIGHT There's more to choosing a quality LED flashlight than just looking for the one with the most lumens. The best flashlights employ a well-designed optics system to create a specific type of beam. WHY UPTICS MATTER An LED (light-emitting diode) can produce a lot of light, but an OPTICS SYSTEM is needed to convert it into a uscful beam. HOW LED FLASHLIGHTS WORK LED CHIP A semiconductor that coverts electrity nto ight. LED OPTICS SYSTEM The optics system gathers and foounes the ight into a usoble beam. The LED chip, mbadded in in apony shal, umta light in all droctiona THROW VS. FLOOD Most flashlight optics are specifically designed to either: THROW light over a long distance or FLOOD a small aree with lots of light.
