It’s Official: LED Streetlights Rock

There are articles all over the news of towns replacing old street lights with LED lighting.  You’ve probably read the reports: LED lighting improves the brightness, visibility, and energy efficiency of street lights.

The DOE recently released a report basically confirming the superiority of LED lighting.  They compared the performance of high-pressure sodium (HPS) streetlights, induction luminaires, and LED luminaires on a street in Palo Alto, California.  Their findings:

• LED used the least energy of the three systems (a 44% reduction compared to HPS – which is the traditional streetlight for most towns).
• LED provided comparable average illumination on the street in comparison to the other two systems.
• LED provided more uniform light output than HPS or induction and had better cutoff – which means the light didn’t overflow onto residential properties as much.

For more information, see the complete report.
