T12 Fluorescent ballast bypass not working
Looking at the Phillips web site it states replacement tubes no rewiring needed.
I do not see anything that states universal. Universal usually have the info on single ended or double ended.
Replacement lamps require a functional ballast.
This is why I say UTube can get you in trouble sometimes guys do not know what there doing. Some times they make it look like they did something getting you to follow their instructions blindly and blow things up.
