[SML] White LED lighting

[Jerry Durand]

> The new "white" LED street lighting which is rapidly being retrofitted
> in cities throughout the country has two problems, according to the
> AMA. The first is discomfort and glare. Because LED light is so
> concentrated and has high blue content, it can cause severe glare,
> resulting in pupillary constriction in the eyes. Blue light scatters
> more in the human eye than the longer wavelengths of yellow and red,
> and sufficient levels can damage the retina
> <http://www.sciencedirect.com/science/article/pii/S001448351400236X>.
> This can cause problems seeing clearly for safe driving or walking at
> night.
