Related to "plastic bulb" of RS plasma globe.  My observation is 
correct but misleading.  On closer inspection the outside of the globe 
is indeed glass but covered with a thin coating of plastic, just 
enough to show a scratch and make the bulb "feel warmer than glass" 
because of the lower thermal conductivity.  Should have kept my mouth 
shut!

too when I bought it.  No model # on it.
