It is severally leaked. This is very common with CMH lamps. I don't know why. |

@Dor123, I don't know why either. I never thought the lamp would permanently EOL quite like this.
Before this occurred, it was cycling. Today when I flipped the switch on, it managed to strike
successfully, warmed up, color shifted but got very dim after that, then there was a very bright
pink/purple flash, loud *tink,* followed by an incandescent glow. Looked like the incandescent glow was from
the small electrodes. I freaked out, and turned the light off. Turned it back on and it did everything
seen in the second video I linked. |

burner leakage is a common failure mode of CMH lamps because PCA is gradually corroded (dissolved) by the pool of hot liquid salt during operation. |

@Max, this lamp had previously been flickering continuously for about a year before all of this began happening.
Should I expect my two remaining 20w metal halides to act the same way before they EOL as well?
Side note... those two remaining metal halides have been working flawlessly ever since I bought them 3 years ago,
aside from taking forever to start during cold starts. |

Flickering could certainly be caused by a change in the lamp chemistry as the molten salt reacts with the PCA wall (more precisely, the release of aluminum iodide as rare earth additives are oxidized at the wall). If this is really what caused the instability you observed, then chances are that you'll also see this occurring with your other GE lamps before they reach EOL. |

I'll keep a strong eye on how they act, and I'll keep you updated. They do flicker very, very slightly, but not noticeably.
I've just operated this EOL MH again to see what it would do, and it continues to do everything seen in the second video I linked.
However... on occasion, I keep seeing a bright blue flash from it. I have a strong feeling that bright blue flash is the arc
tube, but each time it happens, I've been too far from the lamp to actually see it.
Is it possible that maybe this lamp isn't permanently dead? |
