But I don't think here they really mean the frequency or the intensity, maybe I have it wrong but I think they really mean that a given frequency of light could be 'hot' or 'cold'.
"And yet, the Bonn researchers succeeded by using two highly reflective mirrors between which they kept bouncing a light beam back and forth. Between the reflective surfaces there were dissolved pigment molecules with which the photons collided periodically. In these collisions, the molecules 'swallowed' the photons and then 'spit' them out again. "During this process, the photons assumed the temperature of the fluid," explained Professor Weitz. "They cooled each other off to room temperature this way, and they did it without getting lost in the process." This really doesn't sound like they are talking about lowering the frequency or intensity of the light, just the 'Temperature'. And that is without some fundamental discovery about heat or light utterly preposterous. Now maybe it is true, but if it is the headline should be "light has a temperature" not "we can make a BEC photon". They talk about such a photonic BEC creating x-rays, clearly they don't seem to be talking about ultra low frequency. Good point about laser light being very much like a BEC of light, if lasers were discovered today that is precisely what they would have been termed. At thins point you really have to wonder how long this sham can go on, how long they can be considered respectable while the real breakthroughs are being ignored and ridiculed.
