Up here in Canada, we still have cool-white freedom, and probably will
continue to do so until all the US tube manufacturers have completely
depleted their stocks of F40CW. Meanwhile, we can buy these tubes really
cheap. No, I'm not planning to start smuggling them across Lake Ontario
in small open boats...

I'll watch out for that. I always get full 40 watters because I want all
the photons I can get for my tomato plants as well as my aquatic plants.
I didn't know that the energy saver tubes could actually damage the ballasts.
Thanks for the warning.
The fixtures that failed did so by leaking toxic tar. I wouldn't call it
premature death after all their years' service in the factory plus 20 years
for me. Really, these things had cloth-insulated wires, real vintage items.

Let us know what happens. I've found that 40W tar ballasts may be cheap
and plentiful, if you buy them (or find them) used.
