8. LED Roadway Lighting: New York, New York:  FDR Drive Report
On Franklin D. Roosevelt Drive in New York City, LED luminaires from four different manufacturers were compared to the incumbent high-pressure sodium (HPS) luminaires and evaluated for relative light output and performance. (December 2011)

9. LED Ornamental Post-Top Street Lights: Sacramento, California:  Sacramento Street Light Report
The DOE Municipal Solid-State Street Lighting Consortium evaluated four different LED replacements for existing ornamental post-top street lights in Sacramento using computer simulations, field measurements, and laboratory testing. (December 2011)

10. LED Retrofit Lamps: Eugene, Oregon:  Jordan Schnitzer Museum Report
In the Jordan Schnitzer Museum of Art in Eugene, 90W PAR38 130V narrow flood lamps used for accent lighting were replaced with 12W LED PAR38 replacement lamps for a special exhibition, and the museum also staged a side-by-side comparison of three different LED PAR38 replacement lamps against their standard halogen lamp. (September 2011)

11. LED Retrofit Lamps: Portland, Oregon:  Bonneville Power Administration Report
In the Bonneville Power Administration headquarters building in Portland, 15W and 23W reflectorized compact fluorescent (CFL) track lights used to illuminate artwork were replaced with 12W LED lamps. (July 2011)

12. LED T8 Replacement Products: Seattle, Washington:  LED T8 Replacement Product Study
At the Lighting Design Lab in Seattle, LED T8 replacement products were compared to their fluorescent counterparts. These "best in class" examples of LED products are approaching linear fluorescent systems in performance, in some cases showing superior application efficacies. (May 2011)

13. LED Parking Lot Lighting: Leavenworth, Kansas:  Walmart Report
At a new Walmart Superstore in Leavenworth, Kansas, LED parking lot luminaires were installed that achieved a 63% energy savings against a theoretical baseline. (May 2011)

14. LED Retrofit Lamps: San Francisco, California:  InterContinental Hotel Report
At the InterContinental Hotel in San Francisco, halogen wall-grazing luminaires, track lights, and recessed downlights in the lobby and other common areas were retrofitted with 6W LED MR-16 or 11W PAR30 replacement lamps. January 2012)

15. LED Museum Accent Lighting: Chicago, Illinois:  Field Museum Report
At Chicago's Field Museum of Natural History, 32 halogen track luminaires used to light an enclosed gallery exhibit were replaced with an LED system using 26 track fixtures. (November 2010)

16. LED Parking Lot Lighting: Manchester, New Hampshire:  T.J. Maxx Report
In a shopping plaza parking lot in Manchester, New Hampshire, high-pressure sodium and metal halide luminaires were replaced with LED luminaires controlled by integral occupancy sensors that vary between "high" and "low" light output settings. (June 2010)

17. LED Roadway Lighting: Palo Alto, California:  Palo Alto Report
