Osram CFL with bad electronics

Osram CFL with bad electronics

Click to view full size image

Osram 4000K spiral CFL after 4 years of use had electronics failure which caused it to go dimmed to a 1/5 of original output and to flicker like a tube on magnetic gear while before the failure it emitted a stable light.

EDIT:
Analysing comments I've decided to include in main description following observation. This lamp is by naked eye seen as a regular 4000K but dimmed, only the camera due to flicker was able to capture different colors of residual phosphorence. I have photos where it was green, purple etc... I simply have chosen this photo as I've liked it the best.

This luminaire would look better with LED retrofits. I have to admit that I really do not regret the CFL exiting the market.

Soon a LED will take the currently empty place and the other two CFLs will be replaced as soon as they go EOL.

Overall this all happened some time ago, I've never ran it till full EOL, after failure presented here I've put it in the recycling bin.

Any chance of getting a spectrum of that dim, blue CFLi??

Manufactured articles should be made to be used, not made to be sold!

No, as it went to trash years ago. Besides, naked eye seen it as a regular 4000K but dimmed, only the camera due to flicker was able to capture different colors of residual phosphorence. I have photos where it was green, purple etc... I simply have chosen this photo as I've liked it the best.

Interesting how the camera reacted to the phosphorescence. The oscillator inside must have been starting and stopping very rapidly.
