This is a type of coating that is used on the lower portion of a light bulb to direct the light out the end of the light bulb. It provides a more focused beam of light, enabling it to be used as a spotlight or accent light instead of a general room light.

This means that R20 and PAR20 bulbs are the same size. Three types of lighting methods can be used for either R20 or PAR20 bulbs. The first type is the incandescent bulb, in which a filament inside the bulb heats up and makes light when the bulb is in use. The second type is the halogen light, which is a form of incandescent light, but with a difference.
