Aaron also came across some GE demo lamps a while back. Besides those, this is the only other I've seen.

Wow I didn't know they still did inside etch in 1984. Maybe it was for certain smaller lamps?

T12/ t17 there's a reason they made heavy magnetic ballasts

I have inside etch GE F40WWs made in 1987.

May all the great lighting technologies have their place in history.

Not only that. They got the modern longer electrode leads used in GE F40s since the 1980s.

Were Demo lamps meant for lighting displays and this somehow ended up in the rack? Great find, Dave.

do demonstration lamps have any physical difference compared to a normal lamp?

Half of the time they do... half of the time they don't. It depends on the age of the lamp/fixture/kit.

First Bucyrus made F15T8-SP35 I've ever seen. That explains the inside etch. Usually they were from Circleville who were outside etch since 1970.

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