The reviewers conclude that the benefit of light treatment is modest though promising for non-seasonal depression. The short-term treatment as well as light administered in the morning and with concomitant sleep deprivation in sleep deprivation responders appear to be most beneficial for treatment response. Hypomania as a potential adverse effect needs to be considered. Due to limited data and heterogeneity of studies these results need to be interpreted with caution.
