Light is photon. So when in rest (which is hypothetical) photon will evaporate, because the basic property of photon is motion. However having said this, there has been a case when photon has been stopped in the tracks in a Bose - Einstein condensate. I need to find out if they tried measuring the mass of the stopped photon..
