What would you say the object was stuck in the sodium, in the u-bend?, have a close look.....

The only thing it could be is part of the electrode or lead wire??? I've seen some SOX lamps finish their lives rather energetically, but not like that before!

Oh wow, that lamp sure lasted long! Never seen these burn out in real life. But yes...what is that in the U-bend? Is that the parts to the emitter by any chance? Lamp looked like it went out with a bang with the cracked glass......

Love dresses, make-up and just crazy about fluorescent lighting!!  Keep those T12's and magnetic ballasts alive!!

It look like top section of the filament wire. Normally these are beehive shaped, so when first turn break off, it may then look like that...
Don't forget the lamp would still operate - the circuit setup don't care about filament integrity, it only need some connection to the tip and some emission material there, that's all. The wear of such electrode would be fast, but we are talking about EOL lamp anyway...

No more selfballasted c***

Your spot on Medved, this lamp ran all its life horizontally, so I`m guessing it was `spat out` there at EOL, and has set fast in the cooling sodium!!
I have never seen this in a SOX lamp before!
Not for Mr Smashy Mark , I like the unusual death in this one!

@ Brendda, this has lasted a really good long time, normally SOX do about 5 years, but this has excelled itself!, Welcome to LG by the way

Nice pic. The cracked spot looks like where part of the electrode touched the side as it failed. I've seen many fluorescents do that too.
