Mercury Vapor Damaged Electrode Start-Up

Coiled tungsten electrode of a 175 watts Mercury Vapor lamp broke loose and is free moving inside the arc tube. These sequences show the behavior of the lamp when powered up. The arc stream will become unstable and extinguish after a minute or so. The lamp is a 1979 Westinghouse Lifeguard.

Same here with my Osram 125w HQL lamp. At first start arc was flickering but from time that effect dissapeared.
