Abstract: Tungsten halogen lamps require a fill pressure of several atmospheres. To verify the fill pressure at the time of manufacture the pressure is indirectly measured by first measuring the speed of sound within the lamp. A shock wave is produced within the lamp by rapidly heating a lamp filament or producing an arc between two adjacent filaments and measuring the time required for the shock wave to sequentially disturb two spaced light beams passing through the lamp. The speed of sound is determined from the measured time and the pressure is calculated from the speed of sound.
