The newspaper story is about the use of a specific kind of led street lighting at night. One issue is that if humans are exposed to this kind of light at night the brain may 'think' its the middle of the day leading to disruption of the day/night rhythm. Possible retinal damage is also stated. I don't know how similar these street lights are to those sold for houses or reptiles. I've come across them at motorway junctions. I can believe they would keep the brain wide awake.
