Calibration bulbs in the FlexSpec1 spectrograph

Science Spectroscopy

At the Spectroscopy Special Interest Group on Wednesday someone was asking about calibration bulbs. I searched through my email and found the following communication from the FlexSpec1 developers:

NE22 candelabra base bulbs 
have a neon bulb suitable for Halpha work. 
ThAr comes from Australia, Green Scientific, 
no relation.

Hopefully this will help someone find bulbs.
