I have a old building that we installed new cheap (in quality but not necceassirly price) track lighting. I have had continued problems with the connector screws coming loose. Even on ones that I have replaced and know were tightenend securely. Some of the loose connections have caused the connecting pieces to arc and damage the actual contacts. I can't see or hear any vibrations. Is it just crap stuff? I think I bought it at Home Depot or Menards. What Gives?
