7060 Pelican Flashlight - A Flashlight Which Can Last For Up To 100,000 Hours, Light Emitting Diodes

7060 Pelican Flashlight

The problem with the standard flashlight is that either their batteries or their bulbs seem to be dead every time there?s a power failure. Unless you have ultraviolet vision, changing batteries in the dark, assuming that you have them, can be an exercise in futility.

Before 1990, LEDs (Light Emitting Diodes) were used in electronic equipment, digital signs, and key ring lights. A LED is a semiconductor device that emits incoherent narrow-spectrum light when electrically biased in the forward direction. This effect is a form of electroluminescence. The color of the emitted light depends on the composition and condition of the semi-conducting material used, and can be infrared, visible or near-ultraviolet. The main limitation of the LED was that before 1990, it was difficult to adapt LEDs for commercial use because they only emitted coloured light. But then, in 1993, Shuji Nakamura won the distinction of developing the first high-brightness GaN LED which was able to emit bluish-white light.

Nowadays, LEDs are everywhere, and are especially common in flashlights. The advantages of a LED flashlight are tremendous. LEDs can be significantly more efficient at lower power levels, and use less battery energy than normal lightbulbs. LED flashlights also have longer battery lifetimes, and in some cases can run hundreds of hours before the batteries are drained (although the LED efficiency advantage diminishes at higher power levels). Not only do LEDs consume significantly less power than traditional flashlights, but the LED bulb also lasts for up to 100,000 hours.

Because of the extremely efficient nature of the LED bulb, very little power is required to generate bright light. Therefore, a small LED flashlight, such as the Trailblazer LED flashlight (with up to 21 super-bright LED bulbs), generates relatively little heat. Made of durable aluminium construction, Trailblazer?s LED flashlights are made to last. If you consider the fact that LEDs can survive sharp blows that often break conventional lightbulbs, this flashlight could easily last an entire lifetime.
