1. A sealed light emitting diode (LED) light bulb comprising:

  • (a) a base having an integral expanded diameter shell with a flat lower surface, and one or more electrical contact points;

    (b) an LED light source and a phototransistor both electrically mounted to a metal clad printed circuit board, and a two-sided printed circuit board having an upper side and a lower side;

    (c) a fiberglass insulator and a Mylar insulator; and

    (d) a protective cover domewhereby said metal clad printed circuit board is in electrical communication with said two-sided printed circuit board and said two-sided circuit board is in electrical communication with said one or more electrical contacts on said base, andfurther whereby said fiberglass insulator is sandwiched between said metal clad printed circuit board, said Mylar insulator is sandwiched between said two-sided printed circuit board and said flat lower surface of said integral expanded diameter shell, with said shell hermetically sealed to said protective cover dome, forming a sealed bulb, thereby protecting all of the electrical circuitry, the LED and the phototransistor inside the sealed bulb.
