After editing a non lighting related video for YouTube, since I had nothing else to do today, I checked every single lamp ending of every fluorescent lamp I'm using in my apartment, for any possible hotspot movements. All of my fluorescent lighting in use are CFL's, including PL-L lamps on HPF Rapid Start circuitry. Most of my CFL's have "fair weather" end blackening, including my two 2D 38w CFL's. Some have heavier end blackening, but none of which are indicative of potential EOL as of now. The two remaining PL-L lamps that I have used since 2019, are the most likely to have hotspot movement, but nothing crazy yet, and no rapid end blackening.
