White LED spectrum is just 3 narrow(ish) lines - R, G, B.
http://en.wikipedia.org/wiki/Light-emitting_diode.. but this depends on the design. If it is a blue LED with phosphor, then we are in trouble!.
And LED light beam is quite directed by design, compared to traditional bulbs (which are omnidirectional)..
Of course, it depends on future and (non)existing regulations for street lights and their emission spectrum.
