You don't see little labels like that warning about needing ballasts very often.

True...I'm sure someone somewhere thought it would be a good idea to provide a label to prevent misapplication.

I always think a good idea would have been carrying on the use of E29 admedium caps, a bit like the 3-pin BC caps we had here. Always wondered why they didn't (in either case) Wonder

I have to agree with you on that...make it like a key-way where only compatible components work.
