    Can anyone help me regarding LED-fication of Buildings. Where to purchase in bulk quantity? What is the max rating? Can we use it, both indoor and outdoor?

    <a href="https://spectrum.ieee.org" target="_blank" rel="nofollow noopener noreferrer">IEEE Spectrum</a> has had quite a number of articles on LEDs in recent years. All quite fascinating.

    I couldn't find what I was looking for just now, but I remember reading in the print version that LED manufacturers have made very steady and excellent progress improving brightness, efficiency, and spectral range while reducing cost over a 30-year period. And that matches what I've casually observed. Good grief, even the traffic lights are LEDs now.

    -------------------

    Ah! #-Link-Snipped-# may have been it.
    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.

    As said by Ken you've so many choice for LED selection. In india i prefer everlight. And regarding your poll sure LED can replace CFL.

    @GF: The concept is new to me. What is this LED-fication exactly? Does it simply mean replacing lights with cheaper and efficient LEDs?

    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.

    bioramani,

    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?

    Some florescent tubes have a very limited spectrum. I think LEDs offer a greater potential for a fuller spectrum, or as you say, illumination like day light. I would expect that to be a good thing--a very good thing.

    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.
    I dislike fluorescent lighting.
