LED flashlights or "LED torches" (as they are called in Britain) are hand-held flashlights that use light emitting diodes (LEDs) as opposed to the older technology of incandescent light bulbs. They are much more durable than conventional light bulbs and survive sharp blows that often break conventional light bulbs. The expected lifetime for LEDs is up to 100,000 hours. These advantages have made the LED flashlight popular. LED flashlights are often electronically regulated to maintain constant light output as the batteries fade. By contrast a non-regulated flashlight becomes progressively dimmer, sometimes spending much of the total running time below 50 percent brightness level. While most flashlights are intended to be held in the hand, there are also helmet-mounted flashlights designed for miners and campers. Some types of flashlights can be powered by hand-cranked dynamos, electromagnetic induction or recharged by solar power. The name flashlight is used mainly in the United States and Canada. In other English-speaking countries, the more common term is torch or electric torch. LED Flashlights are also known as mini helmet bright torches, handheldlighting lamps, high power white bulbs, super intensity stage spotlight, outdoor emergency preparedness survivalists systems, government issued camping safety supplies, replicas brighter hat equipments, etc. LED Flashlights are commonly misspelled as superbright LEDs, etc.
