Abstract
A tungsten-halogen lamp has a light transmissive, IR coated, filament chamber enclosing a filament, the filament chamber being enclosed within an outer envelope. Fuses are connected to opposite ends of the filament to limit the magnitude and duration of an electrical arc across a break in the filament which, in combination with a fill gas pressure of no greater than 2500 Torr reduces the likelihood of containment failure.
