Total relamp fail

Total relamp fail

These are not MV or SOX firing up. They are CFLs in prismatic ceiling lights designed for them, but either the lamps are poor quality or the fixtures overheat them and they fail early. They first get dim and take a long time to warm up on colder days, or never warm up, and eventually they go pink and then go out. Only months after a full relamp, nearly every light has failed like this (there are many more out of view)

The problem are the lamp quality. Either these gone mercury starved, and the red and green phosphors glowing from the UV from the argon, or the lamps are contaminated which is most likely, as it was occur too fast to be mercury starvation. You can check the spectrum of the lamp using a CD to verify this. If the green, orange and red phosphors emission appears, the lamp is mercury starved, if some bizarre emission appears, the lamp is contaminated.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230V, 50hz country.

It looks more like a batch manufacturing problem - could be contamination causing leaky seals (so oxygen poisoning)...

No more selfballasted c***

LOL at first I thought these were DX MV lamps being operated on low-watt 55V HPS gear, since this is approximately the result I've gotten when doing it. Without the ignitor, the MV won't strike at all, but leave the ignitor in the circuit, the lamp fires up and never warms up all the way. Sad to see this happen with bad CFL lamps on a whole installation.

To resist is to piss in the wind, anyone who does will end up smelling.
