Fluorescent Tube Question.

1) nothing will change unless the tube is faulty, it will strike as before. Perhaps more or less rapidly if the two filaments are volatilizing at different rates.

2) depends how the conversion was done . If the starter has been replaced by a short, then is should work either way round. If L and N only  go to one of the lamp caps, then obviously it will only work that way, and may go bang if reversed, or nothing,,

It is a known problem hence these warning  labels are sold.

That is the worrying point Mike. The new L.E.D. tube is supplied via just two pins L for one pin and N for the other at just one end of the old fitting after conversion. .The old internals are totally disconnected in the old fitting. So just one end cap supplies L and N. SO, if the house holder takes the new L.E.D. tube down to clean it or replace it and then inserts it the wrong way round it creates a DEAD SHORT as the two dead tube pins are shorted together.

Is this a design fault?
