ABSTRACT A tubular incandescent lamp for use in heating applications where multiple levels of infrared energy are available from one source while providing for compactness in size and ease in manufacturing. The primary use for such a lamp is in the fusing system of a photocopy machine where speed in attaining the desired operating temperature greatly determines the machine's rating. In one embodiment of the lamp, quartz envelope is provided with dual chambers extending longitudinally therethrough. A filament extends longitudinally through each of the chambers and is hermetically sealed within press-sealed ends at the opposed ends of the lamp. The filaments are capable of being selectively or simultaneously activated.
