Auroras. Aurora Borealis around the North Pole, and Aurora Australis around the South Pole. It is important to note that auroras have been seen as far south as Florida and Italy; while it is unusual for auroras to be visible in mid-latitudes, it does happen.
There are reflector around LED or lamp to direct their beams to far distance.
The interaction of light beams with a surface is called regular reflection when the light beams reflect off all points of the surface at the same angle. When the light beams hit the surface and reflect off in different angles it is called diffuse reflection.
