1. A method of making an electric lamp comprising:

  • forming an inner light-transmitting envelope having a filament therein and a pair of electrically conductive members projecting therefrom and electrically connected to said filament;

    electrically connecting an electrically conductive reflector at one end thereof to one of said electrically conductive members projecting from said inner envelope;

    securing said reflector at another end thereof to said inner envelope at a location distant from said electrical connection between said reflector and conductive member such that said reflector is positioned adjacent said inner envelope;

    electrically connecting a first electrical conductor to the other of said electrically conductive members projecting from said envelope and a second electrical conductor to said section of said reflector secured to said end of said inner envelope;

    slidably positioning said inner envelope, reflector and conductor assembly within an open end of a piece of light-transmitting tubing such that said conductors are aligned with a predetermined portion thereof;

    forming a sealed end about said conductors at said predetermined portion of said tubing such that parts of said conductors project externally of said sealed end; and

    sealing the opposing end of said tubing to define an outer envelope.
