GE F15T8 Red - All Duds

GE F15T8 Red - All Duds

Found a seller on Ebay who has a case of these and is selling them in lots of four. Unfortunately, these appear to be a bad batch of lamps. When I first got them and tried them (in a LPF Dazor lamp) two of them lost vacuum after about half an hour. I contacted the seller who offered me a partial refund or four replacements. I took the four replacements. Shortly after I contacted the seller the other lamps also lost vacuum. The four replacements arrived and I tested one of them and sure enough, after an hour or so it too lost vacuum. Haven't tried the other three but at this point its likely they'll lose vacuum as well, making eight dead lamps total. Such a shame as normally these are excellent quality lamps and hard to find.

They're from the 4th quarter of 1960.

That's sad.
I guess I got a lot from the same seller (same date code) but I haven't tested them.
Now I'm afraid to!

I hope that’s not due to a partially shorted ballast, I had that happen with a circline adapter.

I decided to try one of mine and it's still working good after three hours. I have my fingers crossed!
