The GATEWAY demonstration project in Sacramento, California, involved ornamental post-top streetlights. The pilot project is the first in a series conducted by the DOE Municipal Solid-State Street Lighting Consortium. The project tested LED ornamental post-top lamp ballast retrofit kits and complete luminaire replacements in comparison with existing 100 watt high pressure sodium streetlights. The LED manufacturers represented included Hadco, Simply LEDs, Sylvania and Sternberg Lighting.

This GATEWAY effort in New York City involved a demonstration project located on Franklin D. Roosevelt Drive. Four LED roadway luminaires were compared with existing high pressure sodium streetlight luminaires. Products from  LSI Industries, LED Roadway, Elumen Lighting Networks, and BetaLED were tested and featured in the report. Tests indicated that the LED luminaires resulted in energy savings of 26% to 57%.

BetaLED – LED luminaires

Deco Lighting – Induction luminaires

Date of report:

Report:

gateway_palo-alto.pdf

 

In this GATEWAY demonstration project conducted in Palo Alto, California, the city performed a side-by-side evaluation of 70 watt high pressure sodium (HPS), induction and LED streetlights. The project studied existing HPS, seven induction and seven LED luminaires.

 

The economic analysis showed that replacing all of Palo Alto’s existing 6,300 HPS streetlights has a simple payback of about 11 years. The lower wattage LED fixtures also showed to be more cost effective than the higher wattage LED fixtures.

 

Citizen feedback indicated that the highest satisfaction was with the 30 LED fixture with the 20 LED fixture, which was followed by a preference for HPS. Induction was the least preferred technology according to citizen surveys.

 

Overall, based on the combined metrics of subjective satisfaction, illuminance performance, energy savings, and economics, the 30-LED luminaire ranked the highest compared to the HPS and induction luminaires.

Leotek, Inc.

Date of report:

November 2009

Report:

Gateway_Lija-Loop.pdf

 

In this gateway demonstration project conducted in Portland, Oregon, eight high pressure sodium (HPS) cobra head fixtures were replaced with eight LED streetlight luminaires manufactured by Leotek, Inc.
Calculations based on the results of the project show an estimated payback of about twenty years for streetlight replacement and just over seven years for new installation. The Leotek fixture consumed about 55% less energy than the existing HPS streetlight.

 

As of November 2009, the LED fixtures have been successfully operating for one year.

City:

Minneapolis, Minnesota, USA

Location:

I-35 W Bridge

Manufacturer:

BetaLED

Date of report:

August 2009

Report:

Gateway_I-35W-Bridge.pdf

 

The Minneapolis gateway project involved a new construction evaluation of BetaLED roadway lighting, which was used instead of traditional 250 watt high pressure sodium (HPS) lights on the newly rebuilt I-35 W Bridge. The LED streetlights were only installed on the main span of the bridge.
The Minnesota Department of Transportation pays a low rate for electricity use ($0.0674 kWh), so the reduced energy consumption of LED fixtures on the bridge does not have a significant financial impact. The majority of the projected savings are due to the reduction or elimination of maintenance associated with HPS streetlights.

City:

San Francisco, California, USA

Location:

Sunset District

Manufacturers:

BetaLED, Cyclone, Leotek, and Relume

Date of report:

December 2008

Report:

Gateway_SF-Streetlighting.pdf

 

This San Francisco Gateway demonstration project was located on 38th, 41st, 42nd, and 44th Avenues between Taraval Street and Santiago Street in the Sunset District. Each manufacturer was assigned a street where its LED fixtures were installed. The LED fixtures replaced existing 100 watt high pressure sodium (HPS) streetlights.
Manufacturers were identified as BetaLED (Company A), Cyclone (Company B), Leotek (Company C), and Relume (Company D). Companies A and C showed the lowest payback periods for retrofit and replacement. Based on the demonstration project’s results, Companies B and D would require significantly longer payback periods.

 

The San Francisco study demonstrated that LED streetlights reduced energy consumption from 50% to 70% when compared with existing HPS streetlights.

City:

Oakland, California, USA (Phase III)

Location:

Sextus Road and Tunis Road between Empire Road and

Coral Road

Manufacturer:

BetaLED

Date of report:

November 2008

Report:

Gateway_Oakland-Phase3.pdf

 

In Phase III of the Oakland, California, demonstration project, all four of the original LED luminaires were replaced with next generation LED luminaires from manufacturer BetaLED.

 

One year after the Phase II report, the payback period had decreased to five years in new construction projects and fourteen years for retrofit projects. The Phase III study also demonstrated significant improvements in luminaire performance and energy consumption. Energy savings increased by 26%, luminaire costs decreased by 34%, and lighting performance was maintained in the one year comparison.

Report:

Emerging_Tech_Report_LED_Streetlighting.pdf

 

Following a successful test of LED fixtures in a city-owned parking lot, Oakland, California, conducted the Phase II project by replacing fifteen existing high pressure sodium (HPS) cobra head streetlights with LED cobra head streetlight fixtures manufactured by BetaLED. Testing demonstrated energy savings of approximately 33%.
Payback period was calculated at 11.6 years for new construction and 19.8 years under a replacement scenario. The payback period for a group installation was slightly longer than the payback period for a single fixture installation
