In colder regions, it is often difficult to start ordinary mercury Iamps at the rated voltage of 200 V. Higher starting voltage for the lamps is required for starting at lower temperatures, similar to that required for fluorescent lamps.
It is difficult to guarantee a satisfactory starting of these lamps at lower temperatures such as-10°C, if argon pressures are appropriately determined considering other characteristics of the lamps. We have made a research on the effects of superposing transient voltages by glow-discharge lamps on the supply voltage of the lamps.
As for the constituent elements of the circuits using glow-lamps, we found that by using condensers, as a resonancing element, the more satisfactory result could be obtained than by using resistances, which merely act as the resistance elements, as far as the starting impulse is concerned. we found that, for example, the starting voltage is lowered to as much as 75 V at-30°C, when 1 μ F condenser is used.
