Led is acronym of words "Light Emitting Diode". It's easier to understand that 1 lightbulb consists of several smaller ones. And that's it....
To complement the process on how to wire a light switch, ensure you have the correct tools available. A screwdriver with a correct head of suitable size, a pair of wire strippers and a roll of electrician's tape are probably the basic apparatus required. Although not often mentioned, it is ideal that you do not suffer from color blindness. It is not a funny matter as the color-coded wiring can sometimes pose a challenge to sufferers. To avoid wiring errors which may cause havoc when the switch is turned on, arrange for an assistant with no color vision deficiencies to help out. Once the wiring is complete, restore your electricity supply and test out the light switch. If all goes well, give yourself a pat on the back.
Why do the colours vary? It is all due to altitude and oxygen molecules and ions at the time. The common colour that is usually on display is a pale yellowish green that is produced by oxygen molecules located around 100 km from the Earths surface. While for example the red auroras are rarer and are formed by high altitude oxygen over 300km from the earths surface. The Aurora can extend from 80 km to as high as 640 km above the surface.
