LED stands for light emitting diode, which is a small, powerful light bulb that is often used in LED flashlights. LED’s were originally used as low-power indicators on battery powered devices, but as the cost went down for LED’s, they became the principal light emitters for flashlights. The Luxeon LED was the first LED that was bright enough and powerful enough to use for a flashlight.

LED flashlights use much less power than ordinary incandescent bulbs. This allows there battery life to last for hundreds of hours on certain models. At higher powers LED’s lose their power conserving advantage, but are still much more durable than conventional bulbs, being able to withstand sharp impacts that would shatter a gas filled bulb. LED’s do generate heat, especially at higher power levels, but because they are almost always used at low power levels the heat level is minimal and often LED’s are mistakenly believed to not produce heat.

LED flashlights often have a power regulator that allows them to remain the same brightness until the batteries are exhausted. Most incandescent flashlights get progressively dimmer as the batteries die, often running at less than 50% of their brightness after the first few hours. LED’s are also much smaller, and very easily coupled with multiple LED’s to increase the amount of light emitted, this makes them good for headlamps, where weight is a major concern.
