I have a lighitng job spec requiring a roadway distribution of LN4, but supplier says a NEMA Beam 6x5 is the same. Not an expert in evaluating these. Can someone confirm whether the same or not?

Sorry but I don't know offhand. You can view IES files for free here: http://www.photometricviewer.com/
The cut sheet for the light should graphically show the distribution. I believe LN4 is forward throw, this could help: http://www.visual-3d.com/education/applicationlessons/documents/application_basics_1.pdf
