A streetlight that can detect floods and prevent disease

[LONDONER]

What I remember reading about LED lights, is that they mimic daylight - thats why they are so disruptive to people's sleep cycle. The older, yellowy lights mimic dusk/dawn, which is why they are so much less disruptive.

So your question has got me thinking now too what effects they might have on wildlife in the area.

That doesn't suprise me at all. I have shutters to my bedroom windows that block out 98% of the light so I sleep in vitual darkness. I am in London at the moment and living with my friend and she doesn't even have blackout lining to her curtains so no wonder I am sleeping so badly.
