Goodstar on amazon has a modification kit, for about $11. You bypass the ballast and run 12V to the tube ends, but there is also a wire in the center of the tube. I don't like that wire.
Goldstar also has a complete 12" 2 tube LED fixture for about $23 with no center wire, but the fixture is twice as thick. The LED tubes on this fixture is the same 12" size and same connections as the fluorescent tubes. Im wonder if I can use those tubes. Remove the ballast and re-wire the current fixture to have 12v on the headstone connectors. I'm concerned with the thickness when closing the shells with the goldstar fixture since the will be over the bed?
