Fluorescent reliability --- In looking for information on Energy Star testing specifications I found this report. It may answer some questions that have been asked on this forum.

Thank you for sharing! Unfortunately, even though much of what the report shows, it is nearly 10 years old. CFL's have come a bit longer ways in terms of longevity, even though the characteristic failures still hold true.

svh19044:

What quantitative data do have to show how longevity has changed?

What areas have been improved?

Nominal voltage was not a problem. Thus, that would not have changed.

Has ambient temperature capability improved? Meaning devices can operate at higher temperatures. Or do the same temperature limits exist and better heat sinking, and/or lower losses reduce the maximum hot spot?

Have there been changes in the on-off life cycle by changes in the emitter (cathode), and/or gas content?
