LEDs to manipulate mood, health, productivity

In theory, solid-state devices (such as LEDs) with "perfect materials and designs" will dramatically reduce (11 percent by some estimates) overall electricity consumption. But it's the ability to control basic light properties (spectral content, emission pattern, polarization, color temperature, and intensity) that has the scientists at the Rensselaer Polytechnic Institute all a-twitter. Not content with merely preventing Soylent Green prophecies, they hope to one day manipulate our internal clocks via "smart" solid-state light sources. These lights would fleece the ganglion cells in our eyes which are most receptive to high temperature color (sunny blue skies) — so lighting that offers the ability to adjust color temperature could benefit (or impede for that matter) human health, mood, and productivity.

pretty colors...........^^

"Wow man groovy lightshow, we're rolling our own jelly babies down here"

Oohh pretty colors.

What would these lights be used for? living underground?

This is great: colours, feelings, and thoughts are all proven to stave off infections of Republicanism.

Naa. Republican and LED promoter since 1992. I love how it creates white light in the center.

I love LED's. Blue is a great color, but I really like white ones.

I <3 LED's.

Mind Kontrol.

How nice, they try to get it this way too, now.

Its not about light... its about FREQUENCY :-D LEDs are very fast acting, you can easily pulse them, even change freq multiple times a second...

interesting idea... puuh
