Failed F40T12 in wraparound

This fixture was the first of a number of new wraparounds installed in the locker rooms at the neighborhood swimming pool back in the late 1980's. This one was installed in 1988 I believe, with GE cool white tubes. The pool operates 7 days a week in the summer months and the lights are on during the entire operating hours most days even though there are skylights. So, the lights do about 1000 hours a year. I don't know the brand of these fixtures but they're quite nicely made.
