Light is a wave and not a particle.

 She disagreed with the article, saying the dark photons have no energy,
unlike particles.

This is what "she" in the video said about the new theory:
"Honestly when I read the headline, I thought this is bullshit.
  But having read the paper I think it's a matter of framing.
  This is a genuinely interesting new way to think about an old
  experiment. But I don't think that talking about dark states
  of light is going to make quantum physics any less confusing."
This means that she accept the "new theory" as a possibly
valid alternative theory to QED.
That may be so, but if it is valid, it would have to predict
the same as QED for any experiment.
I think the world will stick to QED.
In either case, in quantum field theories, light is a particle.
------------------
But remember that a theory of physics is a mathematical model
of Nature, it is not the Nature.
In QED light is a particle.
In Maxwell's theory, light is a wave.
There is no duality in either of the theories.
QED has a broader field of applicability than Maxwell,
it predicts some phenomena Maxwell doesn't.
(e.g. photon-electron interactions)
But the telecommunication we now are using to communicate
is made possible because of Maxwell.
So it is OK to consider light to be a wave according to Maxwell
in some cases. So if you are designing a radio link, Maxwell
is the theory to use,
But there is no way a wave can excite an electron to a higher
energy level, only particles can do that.
QED can predict that a LED will emit light.
Maxwell can't.
