ABSTRACT:
The longevity of an incandescent electric lamp and its efficiency of light production are increased by utilizing a rectifier externally attached to the base of the lamp, and by employing within the glass envelope a gas mixture comprising 75% to 85% krypton and 15% to 25% nitrogen. By virtue of the placement, manner of attachment, and configuration of the rectifier, it dissipates heat to the ambient air and thereby operates at a reduced temperature which increases its performance and longevity.
