I have been noticing that when run base up the very end of compact fluorescent lamps has been turning completly black
Any ideas what might be causing this

These are the pl-9 and 13 watt lamps that this has been happening in

Have you tried operating the lamps in another position?

Usually end darkening occurs from electrode wear.

I don't think it was from electrode wear because the ends did turn dark but the rest of the bulb did to

How old is this lamp?  Is it one of the types that you can change the tubes?  If so, do you have a tube of the correct wattage installed?

here are some pictures of the lamp running
The only way I can get this lamp to light is with a plasma sphere it will not light when I put it in the fixture

These look to have died from old age.  The end blackening is a symptom of normal use.

I have bad luck with lamps from this company. They are a little black on the end but they
 only last a couple of month not the time stated on the package.
