What are the appropriate tubes to use in the generic shop lights?
I'm talking about the fixtures that you see stacked at the end of the
aisle at Wal-Mart for $7.97. I have tried using the 25 watt "for
residential and shop lights" tubes but I find they only last a few
months. I also have tried the F40CW tubes with about the same results.
It is as though the cheap ballast they use in those lamps needs a
certain type of tube. I seem to remember some discussion on this some
time ago, but don't remember the conclusions.
