Adaptive Lighting

Hi everybody,

I'm a senior in the Industrial Design program at the University of Cincinnati. I'm currently working on my thesis project and my topic is light. What started as a concept for creating a new socket for LEDs has turned into something else altogether: replacing current bulbs with ones that adapt throughout the day in intensity and color in order to support a 24-hour circadian rhythm.

Has anyone found that light effects how well they sleep?

I'll be posting similar threads in the SAD and general health sections if anyone is interested to check them out.

Any information or experiences you've had in regard to light and how it has altered SAD would be very much appreciated, and could help make my project that much more meaningful.

Thanks!
