What are LED's and what does it stand for?
LED globes are the latest technology in light globes. The public is quickly realizing the great benefits of led globes verse their ancestor, the incandescent globes
LED does not stand for Lights, Electricity and Diamonds, however it does stand for LIGHT-EMITTING DIODE.

So how does a led work?
When a suitable voltage is applied to the leads of a LED, electrons are able to recombine with holes where the electron use to be known as electron holes within the device this in turn releasing energy in the form of photons. Now the fancy science word for this process is known as electroluminescence.
An LED is often small in area less than 1 mm2 and may have integrated optical components.
LED have appeared in practical electronic components since 1962, the earliest LEDs emitted low-intensity infrared light. These Infrared LEDs can still frequently be used as transmitting elements in remote-control circuits, such as those in remote controls. The first visible-light LEDs were also of low intensity, and limited to red light. Now days LEDs are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness. Making them extremely useful.
LEDs have many advantages over their older cousins the incandescent light. including lower energy consumption, longer lifetime, improved physical strength, are smaller in size, and instant light. Today you can find Light-Emitting diodes in many applications, from aviation lighting, automotive headlamps, advertising, house hold lighting, traffic signals, camera flashes. They can even be found in the latest TVs giving greater definition and lifespan then they old plasma
LED come in color's like Warm White (known as 3000k), Cool White (known as 6500k) and Daylight (5000k), we are talking in regards to the common house-hold globes). The color of the light is determined by the energy from the corresponding photon known as (band gap of the semiconductor.)So now you can go ahead with confidences that you can get those extra bonuses points at your next trivia game night
