Television and Film Applications of Tungsten-Halogen Lamps

Tungsten-halogen lamps for TV and film applications have been rapidly developed with design requirements of portability, compact size and efficient performance. Families of these lamps provide interchangeability in wattage and color temperature. First came the group of double-ended lamps; later, single-ended lamp designs were developed. Because the lamp filaments are very compact and the bulb envelopes are small, optical system design is facilitated. The usefulness of these lamps has been shown by their providing increased light output and/or increased life, including their use in projection systems.
