These are old, 48-inch, T-12 tubes. I'll need to buy four as all seem pretty dark at the ends. I was not sure if this older-type of lighting is still being produced. I remember when our building changed to newer fixtures on all the parking levels. At the time I read that T-12s would eventually be phased out.
This would be an excellent time to go for a new, more energy-efficient, fixture. If these had burnt out at the beginning of the summer, we might have. Yet as we have only two weeks until we leave for the winter, I guess I'll just run to the hardware store for replacement tubes. I see they are still listed on the online websites.
