Abstract

This invention relates to an electric lamp (10) formed from a quartz tube (30) incorporating a U-bend (33). The filament (20) lies within a hollow central region (31), which is sealed at each end (32) in an airtight manner. Specific positioning means (40) are provided in the lamp (10) for insuring that sections of the filament (20) lie along these central axis of the puartz tube (30).
