Great for S.A.D.
My hubby works a 3rd shift and in the winter time rarely sees the sun.  It's dark when he comes home and dark when he gets up.  I put this little light on his end table in the living room.  He says that this little light definitely made him feel less depressed.  I also installed full spectrum bulbs where he spends the most of his at home time.
