Unlike the other GE colored fluorescents I got, this is a later one with an ordering code and outside etch.

Too cool! You gotta get some pics with these lit up!

Preheat Fluorescents forever!
I love diesel engines, rural/farm life and vintage lighting!

Looks like '77 lamp because a '87 etch had a smaller "meatball."

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

Thanks Jerry, I was leaning towards '77 also. Because of the neater etch than 80s etches and also the short electrode leads. I was a bit confused by the lack of the Mainlighter name tho.

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

Yeah same here Dave...no Mainlighter/the short electrode leads...there used to be some /CW at my work that has the same etch that lacked Mainlighter as well. I will look to see if any are left.

The Mainlighter name was used on general service lighting lamps such as CW,CWX,WW,WWX,SW/N&D.

It was not used on color or BL lamps.

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