I was of understanding that all mass/energy was wave-like at its heart configured on a 
continuum from pure sine waves to "localized lumps" termed particles.
 I found this reference in an answer from your archives:

Ill end with a quote from Richard Feynman from his
book QED (Chapter 1).  He won the Nobel Prize in 1964 for his
explanation of quantum electron dynamics:

I want to emphasize that light comes in this form  particles.  It is 
very important to know that light behaves like particles, especially for 
those of you who have gone to school, where you were probably told 
something about light behaving like waves.  Im telling you the way it 
DOES behave  like particles.

My question is-Is Feynman asserting that light always behaves as "localized wave packets" -or 
something else ? Please elaborate. Thank you.
