LED Downlight

A downlight can be defined as a light that has been recessed into a ceiling and that throws light downwards in a narrow beam.  When it is turned on, it looks like light is shining down out of the ceiling.  Downlights are comprised of a housing that is inset into the ceiling, the bulb, and a transformer (if necessary) in order to convert the power voltage into one that is safe for the downlight to use.
