@xmaslightguy, highly agreed. I actually had to take apart literally every socket in all five of the "LED ready" fixtures in my upstairs loft, to get them prepared for the wiring of each HPF magnetic Rapid Start ballast that I installed. I had to open up the "back door" of each socket, force the tabs up to release the LED ready wiring, insert the copper portion of the ballast wiring, then re-bend the tabs downward to further guarantee official contact with the tabs and the copper portion of each wire. After that, I'd close the "back door" of each socket. After applying power supply to the ballast, using only one lamp, I checked for visible electrode filament heating on both sides of each ballast. I did this with all of my fixtures, and all of them passed the test. (Except for that one ballast I told you about in the middle fixture. That is the only one that had an issue with filament heating. I'll be checking that ballast soon.)
But all 11 of my fixtures are working flawlessly with each and every start up so far, although I know for a fact there was probably an easier way for me to handle the "LED ready" socket wiring during ballast installation.
But yeah... the tabs making contact with the copper portion of the ballast wires... that's a big deal. It may seem as if the wire is snug in place, but that does not mean the copper portion of the wire is making contact with the tabs,
