Store-brand F34s I don't think I ever posted. Someone gave this pair to me years ago and I've had them in this particular wraparound light almost ever since. Typical dim, gloomy, 34-watt lamps, especially in the unheated shop, (they only start without striating on the hottest of hot summer days!) but they work well on the cheap low-power-factor rapid start ballasts in residential fixtures.
They are just a GE "Watt-Miser" in disguise. Ace and True Value GE-made fluorescents were everywhere around here when I was a kid. These must be mid '90s-mid '00s vintage. Can someone date them specifically?
An interesting thing on the 34w lamps is that on cheap, wimpy ballasts when starting a glow starts at the ends and "crawls" to the middle, often with "sparkling" at the electrodes. This pair in particular, on this particular ballast, is a good case in point, for those who like "startup flicker" on rapid start.
