Full title and description

ANSI ANSLG C78.357-2010 — Incandescent Lamps: Tungsten Halogen Lamps (non-vehicle). This American National Standard specifies performance requirements for a range of tungsten‑halogen incandescent lamps (single‑ended, double‑ended, integral reflector, and PAR types) intended for projection, photographic, floodlighting, special‑purpose, general lighting service (GLS), and stage/studio applications, with rated voltages up to 277 V.

Abstract

This standard defines electrical and photometric performance, operating conditions and testing expectations for non‑vehicle tungsten‑halogen lamps, including dimensional/physical characteristics where applicable, rated voltage limits (up to 277 V), and application categories such as projection, photographic, floodlight, GLS and stage/studio use. It is intended to provide manufacturers, test labs and specifiers with uniform requirements for design verification and product comparison.

Scope

Specifies performance requirements and test methods for non‑vehicle tungsten‑halogen incandescent lamps (single‑ended, double‑ended, integral reflector and PAR geometries) rated to operate at voltages up to 277 V. The scope covers intended applications including projection, photographic work, floodlighting, special‑purpose lighting, general lighting service and stage/studio uses, and is intended to provide consistent parameters for manufacturers, testers and purchasers.

Key topics and requirements

• Performance requirements (electrical and photometric) for tungsten‑halogen lamp types covered by the standard.
• Classification of lamp types: single‑ended, double‑ended, integral reflector and PAR constructions.
• Rated voltage limits and operating conditions (covers lamps with rated voltages up to 277 V).
• Application categories (projection, photographic, floodlight, GLS, stage/studio) and recommended use cases.
• Test methods and measurement practices for verifying lumen output, life, voltage/current characteristics and other key lamp metrics (as defined in the standard body).
• Reference to the broader C78 family of ANSI/NEMA lamp standards for complementary dimensional, safety or measurement requirements.

Typical use and users

Primary users include lamp manufacturers, product designers, laboratory/test houses, quality and compliance teams, lighting specifiers, procurement professionals and standards writers who require uniform definitions and testable performance criteria for tungsten‑halogen lamps used in projection, photographic, flood and stage/studio installations. The standard is also referenced by programs and specifications that list accepted lamp standards.
