I cannot help you any further I'm afraid but I will make the following comment for anyone else who might find it useful.

LED replacement tubes require no starter and you connect them to the mains via a switch in the same way that you would wire a normal incandescent bulb. None of the 'guts' associated with a conventional fluorescent tube is required. I cannot think of a fitting that could not easily be modified.

In every LED replacement I have ever had there is a sticker to fit under the tube to make it clear that the fitting has been modified for LED tubes only.
