Streetlight LED Conversion

[notmyfriends]

In general, it should not be necessary to boost output (exceptions exist, but then there are probably also places where the output can be reduced).

I'm not so much convinced, though, that the colour temperature of street lights is such a huge factor for human sleep patterns.  For indoor lighting (to which people are exposed to for much longer periods of time) it might be more important. 

And there is less light pollution. From CBC's article:

Besides saving the city money, the LED street lights may also have other benefits, says Chapman.

"Cities that have deployed LED street lighting have found that because they're so much more focused, they reduce the amount of urban sky glow.

"So there are people actually in the city of Los Angeles, where they've deployed LED street lighting, where they can actually see the stars again in the middle of the city, which is quite exciting," said Chapman.

That part in the quotes is very anecdotal and you can find many articles suggesting the opposite is happening in places wrt light pollution. Again this just says proper and thorough research before implementation is required.
