Today when my halides came on, the 14k on the far right of my Aqua-Medic began to make a sparking or sizzling noise every 5 to 10 seconds for about 1 second each time. When I turned off the lights, and took out the bulb, the end of it had several grains of black crumb-like material fall out off the right side of the bulb on the metal strip (see pic below). This has happened on a bulb in the same slot in my light. My LFS owner seemed to think it had something to do with my powerful German magnetic ballasts on the first bulb, so he gave me a better quality German bulb rather than the initial Korean bulb. I have not talked to him since this bulb has had the black burning residue.
Can anyone tell me what is causing this? Thank you.
Peace, Poppinthekap
