Christmas Lights

Article

NASA is changing the lighting in the big space box.  They have finally realized the importance of the colour of lights during the day.  As a northern sufferer of seasonal depressive changes, you have to be real careful.  Get a blast of bright bluish light in the morning, but warm out the light by evening.  I think that at Christmas a lot of people might be getting these 'full spectrum' lights.  Do not use them in the evening!  I'm currently slowly replacing the most used lights with LED 'warm white' lights.
