These have a nice color. The number going down the right side of the etch is A848. Is this the date code?

Thank you! So they're not pre-EPACT, but the color is still better than post-EPACT F40s.

The Danvers plant closed April, 1998 so these were among the last.

Preheat and T-12 fluorescents forever! Down with LED's and instant start T-8 fluorescents.

Are these special lamps? Should I run them or save them?

Nothing special..
Maybe save one, run the rest.

Forget the lights..just give me a good lightning storm & tornado to go watch...

8=1998, 4=April, 8= Monthly cycle. This is for the '95 to now ones.
