I'm replacing florescent tubes with Westgate T8 LED tubes (T8-EZ4-18W-40K-F), which work both with or without an existing ballast (I remove the ballast when I install them). When bypassing the ballast, you have the option of wiring just one end, or both ends (I wire just one end).
One end of each tube has this warning:
This end is short-circuit. Don't instant wire in AC.
What does "instant wire" mean? My best guess is that it's alluding to instant-start ballasts, which usually use shunted lampholders, so is it just saying to be sure to use a non-shunted tombstone at that end when bypassing the ballast?
The diagram seems to suggest that I shouldn't use that end of the tube if I have only wired one end of the luminaire, but I don't see how that relates to the text "Don't instant wire in AC".
The package insert and the manufacturer's website don't mention anything about this.
