What is BS EN 60357 – Tungsten halogen lamps about?
BS EN 60357 is an international standard that discusses the performance specifications of tungsten halogen lamps (non-vehicle). The tungsten filament of a halogen lamp has two purposes. One is to generate light, and the second is to generate the heat necessary to obtain a wall temperature exceeding 250ËšC.
BS EN 60357 specifies the performance requirements for single-capped and double-capped tungsten halogen lamps, having rated voltages of up to 250 V, used for the following applications:
- Projection (including cinematograph and still projection)
- Photographic (including studio)
- Floodlighting
- Special purpose
- General-purpose
- Stage lighting
Who is BS EN 60357 – Tungsten halogen lamps for?
BS EN 60357 on tungsten halogen lamps applies to:
- Manufacturer of halogen lamps
- Quality testing personnel
- Suppliers and distributors of tungsten halogen lamps
- Electrical engineer
Why should you use BS EN 60357 – Tungsten halogen lamps?
A tungsten halogen lamp is a gas-filled lamp containing halogens or halogen compounds, the filament being of tungsten.
BS EN 60357 navigates you through the lamp requirement where a lamp is designed, its performance is reliable in normal and accepted use. In general, this can be achieved by satisfying the requirements of the following subclauses.
BS EN 60357 provides the maintenance and centre beam intensity maintenance where the lumen maintenance of a tungsten halogen lamp, at 75 % of rated average life, is not less than 80 % of the rated lumen maintenance value. The centre beam intensity maintenance of a tungsten halogen reflector lamp, at 75 % of rated average life, is not less than 80 % of the rated centre beam intensity maintenance value.
