Today, I have had a go at calibrating the homemade RELCO Starter bulb calibration lamp I made against 12V compact fluorescent lamp bulb in order to determine the wavelengths of the main lines on the CCDSPEC spectrum of the RELCO bulb.

Also look at https://stargazerslounge.com/topic/226911-neon-lamp-to-set-spectroscope/?tab=comments#comment-3521335 to find out what happened when I tried to compare the lines I identified below with the atlas of lines from http://www.ursusmajor.ch/downloads/sques-relco-sc480-calibration-lines-5.0.pdf – sadly they don’t seem to match!

Graphing both above spectra together:
Calibrating spectra of both RELCO and CFL using above two lines in RSPEC gives following calibrated spectra:
