Phoenix converts street lights to brighter LEDs

If Phoenix streets are starting to appear brighter, it's not the moon nor the viewer's imagination. The city has begun installing new street light fixtures with LEDs, or light-emitting diodes, that shine a noticeably whiter, clearer light. The city has begun an effort to convert its about 90,000 street lights to the more energy-efficient fixtures by summer 2017, replacing older high-pressure sodium bulbs that give off an orange-yellowish light.
