Bob, the other tube was fine from tip to tip. The problem bulb was also cool to touch at the opposite end from the end pictured here. So, in a 2 tube setup, only one end of one bulb got this hot. Same thing happened 2 weeks ago with a different tube. I believe that there is something wrong with the ballast and/or wiring. For now, I'll use phillips 40w actinics wired in parallel.
