I have to take time to look this up, but I would just say be careful of the terminology.  I seem to remember from my wife's interior design lighting class that these are two separate definitions in photometry (think it was a test question she got wrong).  I appreciate the distinctions you are trying to make, but you may wish to make sure your usage is consistent with international standards...if you care.  So long as you know what you are using the term for, I guess it does not matter.
