Follow the link and there is a published paper. In fact there are two: one showing their experiment with light emitting earbuds and the other showing possible light receptors buried in the brain. This is not my field (and I assume it is not yours) so I cannot refute their claims. So far they have done an experiment and they have a significant result—in fact it is so significant that it is easily observable (10 out of 13 rather than the expected 6.5). There are three likely reasons for this result 1) Experimental error 2) Placebo effect 3) Brains react to light. The likelihood is probably in that order. If they, or another team, can repeat this finding in a double-blind test then I will be comfortable in accepting it. This is not bad science. It may be questionable business practice to move so soon on this (especially before a double-blind test) but it isn't total quackery.
