Washington, DC is starting to switch to LEDs for streetlights. They're whiter than the old sodium bulbs, but the District uses 3000K lights for main streets and 2700K for residential streets. The LEDs are directed towards the ground at a 45° angle--the globe diffuses the light, but they produce much less light pollution and they'll save a ton of power, time, and money.
