not just the light temperature (2700K would be better), but the idea that a street light must be a bulb boxes in the design. led lights can be made in any sort of configuration, since it's an amalgamation of bunch of small point sources, not just one big point source.
it would be neat to have light strips alongside the sidewalk and the road, as well as above. that way, the light can be lower intensity in aggregate while still providing the necessary illumination (via surrounding light vs. flooding) to make out details. our eyes are highly adaptive, and we don't need a lot of light, but rather, light from many angles.
also, the safety argument is often overstated in relation to the intensity of light. you only need a little light to reduce crime and accidents to its threshold. more isn't better in this regard.

Compact light sources aren't recent invention, and various lighting methods were tried. I think pylons with bulb boxes still come out best in illumination quality vs. price/maintenance.
