BA9s Tungsten Halogen MCC

MBC tungsten halogen filament lamps suitable for use in emergency spotlights
Ideal for applications where an extremely high light output is essential

Torch Lamps

Filament lamps will perform to specification and give optimum life when: they are powered at the rated voltage from a stabilised 50Hz ac supply; the ambient temperature is in the range +20°C to +25°C; and no mechanical vibration is present.

Deviations from these criteria can have a significant effect on lamp life, particularly with low current filaments (<80 mA).

Operation from a dc. supply at rated voltage can reduce specified life by up to 50%.

The effect of variation from the rated operating voltage should be noted: 5% above will reduce lamp life by up to 50%; and 5% below will significantly increase lamp life.

Current consumption can vary by up to ±10% on stated values at rated supply voltage. Care therefore should be exercised when running a number of lamps in series. In such applications it is recommended that the rated voltage be reduced by 10% to prevent premature failure of individual lamps.

Conversion of light output units: Lumens = MSCP x 12.6, MSCP = Lumens / 12.6.
