There are 'okay' LED streetlights and there are 'bad' LED streetlights. Most of Phoenix's new streetlights are three LEDs pointed down. It seems like some of these use ~5000K leds (daylight / blue-white), while the others use ~2700K (much closer to incandescent). Some of the 2700K-ish streetlights lights I've looked at recently have different power output - a dimmer one was 'okay', the others were uncomfortable to be in the vicinity of. All of Phoenix's new lights have no diffusion effect - they just have three LED chips pointed down. I commented on a recent submission about the invention of the frosted light bulb [0], which were more popular than the previous bulbs because it diffused the light generated by the filament. Another LED streetlight model I've noticed (not in Phoenix) has a much more diffuse effect, because it has dozens of LEDs poined in different directions. That intersection, while inferior to the previous amber LPS bulbs, wasn't an active hazard, just mildly annoying. Flagstaff, Arizona has some amber LED streetlights. They're too intense (too bright), but they're not painful to be in the presence of, as long as I don't look directly at the amber LEDs.
