It's the wrong colour for a printing safe-light and there's white light emanating from the end! A bit bright too.

Unless it was mounted behind a deep-red well-glass, of course. I have several coloured lamps (greens, yellows, blues, reds... similar vintage) and they were last used in anger on a sort of poor-man's 'disco-ceiling' at our works social club.
