visible light when charged with an electric current<br />

• LED uses at least 75 percent less energy than<br />

incandescent<br />

• Remote controls use LED’s that emit infrared light<br />

• An incandescent bulb heats a filament to create light<br />

through this it gives off only 10 percent of its energy<br />

as light and the rest as heat<br />

• The father of the visible light LED - nick Holonyak<br />

• LED can direct light where it is needed<br />

• Incandesent and fluoroscent bulbs emit light and heat<br />

in all directions which is wasteful<br />
