1. A method for manufacturing a hermetically sealed LED light, comprising:
assembling at least one LED on a base made of ceramic;
providing a metal cap having an end with an opening surrounded by a peripheral depression;
melting a glass into the opening to define a window in the opening, the window having a a lenticular shape due to surface tension of the glass that does not protrude beyond the end of the metal cap; and
soldering the metal cap to the base using a metal solder so that the at least one LED is within the metal cap.
