A paper on possible health effects of LED lighting

Been busy doing other things, so no news for now, sorry.

But I came across an interesting paper:

International Dark-Sky Association - visibility, environmental, and astronomical issues associated with blue-rich white outdoor lighting (pdf).

Seems blue light can be hazardous. And thus it might not be a good idea for highway authorities to switch from HPS to LED just yet.
