Medium Pressure Mercury Vapour amp Osram 400W mercury lamp type MA/V with some hours on it. This lamp works fine but on very close inspection the start series resistor is detached from the circuit by less than a mm. As the outer jacket is at low pressure but not a good vacuum a conduction path across the gap allows the lamp to start normally. Keywords: Lamps

Medium Pressure Mercury Vapour amp

Osram 400W mercury lamp type MA/V with some hours on it. This lamp works fine but on very close inspection the start series resistor is detached from the circuit by less than a mm. As the outer jacket is at low pressure but not a good vacuum a conduction path across the gap allows the lamp to start normally.
