I got my 40w, 2G11 base. bulbs ready to fit to my 2x40w ballast. Wiring diagram on the ballast looks fine and I have the correct wire. I believe my ballast is suitable. However, the ballast states TC-L whereas the bulbs say PL-L.
I have not been able to find an answer by searching the internet as to whether any difference exists in the real world rather than just some difference in labelling terminology. Several places use TC-L and PL-L interchangeably as if there is no difference. Bulbs look the same and have the same 2G11 fitting and wattage ratings.
Just as an example please look here (example from one of my searches):
Anyone in the know who can tell me something about PL-L vs TC-L thankyou in advance.
