thanks for your answer but It doesn't change anything.

I think my light point is well defined because it has been constructed by
the openFlight loader.
If I have a look to the pfNode stemming from
 pfdLoadFile(myFile), everything you told me to be set is done.

I think my problem comes from order or definition of rendering.
