With every decade since 1970, when the red LEDs hit their stride, they have gotten 20 times as bright and 90 percent cheaper per watt; the relation is known as Haitz's Law, and it applies also to yellow and blue LEDs, which were commercialized much later. ...
They now have everything they need to dominate lighting, except for a low enough price. But that, too, will soon come.

Some work is going on in LED glow panels in which a flat panel flush with the wall or roof surface glows. The effect will be a shadow free illumination like day light. I do not know what this would do to circadian rhythms of the body. Biologically we need to differentiate between day and night. Otherwise it will create sleep problems, which may not mean much to CEans, who are already down the tube anyway.Issue@GF: The concept is new to me. What is this LED-fication exactly? Does it simply mean replacing lights with cheaper and efficient LEDs?

There is no health hazard. All I meant was that such an illumination, though shadow free and easier on the eyes, will give an impression to the brain of a longer daylight period and therefore modify sleep behaviour. I am personally in favour of such lighting.KenJacksonbioramani, Are you saying that a ceiling of uniform glow panels would be worse for the body than today's common rows of florescent tubes? I'm skeptical. Is there more information?
