 A between-subjects double-blind comparison of 3-weeks treatment using narrow-band LED panels at blue 468 nm at 500 mWcm2 vs red 700 nm at 15 mWcm2 wavelengths in 24 SAD patients demonstrated both greater reductions in depressive symptoms and also remission rates 54.5 vs 30.8 in favor of the blue light source Byrne et al., 2004. Comparisons of this narrow bandwidth blue LED light with white light would be of even greater clinical interest since white fluorescent sources currently are the industry standard.
