Date code for vintage GE ballast « on: June 19, 2023, 10:41:29 PM » Author: Preheat_Carson
I have a GE pre heat ballast with cloth wires for 2 40 watt fluorescent lamps.

The date code is WG

There is a number 3 on the ballast also

Can anyone tell me how old this ballast is?

Cat. 58G983

I love vintage fluorescent and modern LEDs. Just wish they would stop the bans on fluorescent when they make LEDs!

My best estimate would possibly be sometime between the 1940s and 1950s.

GE used to have a date code chart for ballast
 On the  internet.  To tell if a ballast have PCB or not

IIRC for one of these older ballasts, you might have to use a spreadsheet to extend the code pattern to cover the 40s and 50s.
