How much power plant electricity goes to lights as opposed to other uses?
If these lights allowed us to reduce the demand for electricity for light usage by 90%, how much impact would it have?
Would it have a significiant impact on the demand for oil? the demand for natural gas?
There would be some offsetting trends, people would leave lights on more, there would be more outside lighting, etc.
Personally, the one thing I liked was 'led lights don't produce heat' That would seem to indicate that you could have savings in other areas, maybe not in a home, but in industry that uses lights 24/7 and also cooling. Less energy to produce the same light combined with less heat...would there also be energy savings in the cooling? Perhaps not significant in one place but if all industry did that? I don't do science, I just ask questions and let those knowledgeable in the area tell us :)
