Cape Light Compact, through its energy efficiency program and on behalf of the participating Cape Cod and Martha’s Vineyard Towns and certain Fire Districts, is advancing a full conversion to light emitting diode (LED) street lights of approximately 15,000 existing municipally owned fixtures that will bring significant long-term energy and cost savings while meeting or exceeding current lighting levels.  LED technologies selected and designed for this project are expected to use 70% less energy, an increase over the original estimates of 40-50% savings, and last longer than existing streetlights, thereby lowering municipal budget maintenance costs.  Cape Light Compact anticipates to change over all streetlights, in the participating towns and fire districts, by mid-2014.

The estimated project schedule is attached here (CLC-estimated-schedule_audit_phased-approach-1.xls) and includes a detailed field AUDIT with a street-by-street canvas of all roads to locate all light poles and map them in a GIS-based system that will include existing fixture information and provide an accurate inventory for confirming LED replacements and energy and cost savings.  The work will be conducted in phases as shown here

For more details on the full conversion project please click here (CLC-Siemens LED Project Kick-off Meeting 10-2-2013) for the kick-off meeting presentation!

Here’s an updated savings comparison by participating municipality Comparison Table 9-4-2014  (this table will be revised as field audit, engineering/design calculations are completed).

Here is a set of answers to FAQs for Town DPW, Highway, Fire District and all Project Lead contacts about the full LED conversion project FAQs-2013-11

Cree Beta LED XSP1
is the primary fixture solution selected for the full conversion project

This fixture looks similar to the old high pressure sodium (HPS) cobra head type fixtures that are being replaced and meets or exceeds all project specifications, including:  highest product efficiency, warm color temperature, optical and lumen control along with a 10-year product warranty.

The Cape Light Compact undertook a demonstration project that evaluated new LED streetlight technology to confirm the estimated energy savings, fixture performance and gain feedback from our communities.  The demonstration streetlight installations began in January 2013 in approximately 8 selected residential and commercial/business locations in each Cape Cod and Martha’s Vineyard town (or fire district) who own their fixtures.

FEEDBACK SURVEY IS COMPLETE.  Thank you to the more than 90 citizens who provided helpful feedback that will help us in the full scale change out of light fixtures that we are planning for in 2013-2014.

DPW DIRECTORS Meeting Presentation of May 3, 2013 is attached here at DPW Mtg 5-3-13 FINAL and describes results of the demonstration project and next steps to prepare for the full retrofit project.

The U.S. Department of Energy produces some great Technology Fact Sheets  describing solid-state lighting, its characteristics, applications, and issues relating to its successful introduction into the marketplace.  This document describes current photobiological safety standards, and specifically reviews the optical safety of LEDs with regard to blue light hazard. (4 pages, June 2013). 

PERFORMANCE MATTERS when it comes to choice of streetlights and lighting in general – here is a one page summary of the five (5) key performance metrics that go into evaluation of lighting product choices Luminaire Performance Metrics

 We are a member of the U.S. Department of Energy Municipal Solid-State Street Lighting Consortium to share and learn from communities across the nation who are advancing the use of light emitting diode (LED) technology in roadway applications.

Please click Resources for more information including: technology fact sheets, model specifications, Gateway demonstrations & more.

Here’s the Installation Schedule as of 7-16-2013. Please note that this is updated periodically, so please check back!
