So, in fact, water will evaporate without heat because of the lack of equilibrium between air and water, until the air is wet enough for the process to stop.
Discovering that light vaporise water is not the same as discovering that water vaporise itself without heat. It is an interesting discovery nonetheless.
Up to 3 times more water evaporated than heat energy the light could supply.
It's pretty massive if true.
