[GreenKeys] ST-6 neon lamp part number

[Bruce Gentry]

Neon bulbs do not have a getter, so gasses imbedded in the glass can 
come out and contaminate the neon. Atmospheric gasses may diffuse 
through the glass. The neon may embed itself in the crystalline 
structure of the electrodes.  Neon sign tubes must have new electrodes 
installed and be re-evacuated and refilled periodically, usually 
measured in decades. They tend to require this more frequently if they 
are lit constantly. They are very long lived, but not forever.
