battery powered fluorescent lamp

Battery-operated fluorescent lighting projects often appeared in hobby electronic magazines in the 1980s. I always thought that fluorescent lamps were devices that only used AC power at that time. Those articles about using batteries to light miniature fluorescent lamps attracted me. I made some fluorescent lights, but I couldn't get good practical use out of them from a lamp efficiency and longevity perspective. That's because I was just reading the article and knew nothing about the theory of discharge lamps or even electronics. I don't know what to change to get good results, and I'm losing interest in it. However I found a battery powered fluorescent light project online that was identical to the schematic I was working on. So I "revived" the project after 30 years with modern driver circuits and correct theory.
