Hi,
here iam finding difficulty to know the reason behind blackening of tubes ....
what is the reason that when a tube is switched on the ends will glow orange in colour
and the middle part will be black.... i know that this indicates that the life of
the tube got over. Please let me know the reason behind this process...
