Delmarva Power LED STREET
LIGHT PILOT PROJECT
• Background
– 2007 Utility Distribution Standards employees began researching
LED Technology for roadway use.
– Information obtained from pilots in the City of Ann Arbor,
Michigan and Toronto, Canada identified two manufacturers Relume and Lighting Technology (Leotek); a third manufacturer,
eLumen, was identified in 2008 for evaluation.
– Additional LED manufacturers are introducing their products.
BetaLED has submitted a sample for installation; Howard
Industries Lighting Division and Holophane have recently
introduced cobra head models.

LIGHT PILOT PROJECT
• Objectives of Pilot
– Investigate LED technology in a cobra head application to
replace existing lights, and also to replace High Intensity
Discharge (HID) lighting as it is phased out in the future.
– LED evaluation criteria would verify the following:
•
•
•
•
•
•
Power consumption
Ease of installation
Lumen output
Quality of product
Luminaire life rating
Input from customers
– Compile information, determine viability of this technology,
publish report and potentially establish tariff rates.

Objectives of Pilot (cont.)
– Identify standards to ensure uniform performance and product criteria.
(i.e. IESNA RP-8-00).
– Look to manufacturers to identify various issues which can affect
uniformity of product.
•
•
•
•
•
Lumens per watt release
Agreed-upon wattage classifications
Dark Skies compliance
Heat dissipation/management
Warrantees for premature failure
– Gain customer interest and input:
• Glare issues
• Coolness of light for high color temp fixtures

Delmarva Power LED STREET
LIGHT PILOT PROJECT
•
Pilot locations selected to meet proposed criteria:
– Select area that can establish pilot and product comparisons within a
compact area
– Select an area that may contain vehicular traffic, pedestrian traffic,
limited/no tree intrusions, etc.
– Select area that proposes safe working conditions for employees while
light products are installed and tested
•
LED Pilots established in four Delmarva Power regions
–
–
–
–
•
City of Wilmington
Town of Elkton
Town of Chestertown
Town of Georgetown
Each pilot location to consist of ten LED lights representing two
different manufacturers.

Delmarva Power LED STREET
LIGHT PILOT PROJECT
• For first pilots, Delmarva Power is working with several
LED manufacturers to provide a variety of fixtures
currently available
• Primarily focused on cobra head fixtures to replace
existing incandescent and HID lighting (MV and HPS).
• Selections based on ability to meet lumen output and
light patterns/distribution for replacement of existing
fixtures

LED Demonstration Area – Delmarva Power has installed several LED cobra head
fixtures on Broom Street between Concord Avenue and 23rd Street.

Delmarva Power LED STREET
LIGHT PILOT PROJECT
• Implementation Plan
– Select LED fixtures to be installed and evaluated for about a six
month pilot.
– Execute a Memorandum of Understanding (MOU) between the
selected municipalities and Delmarva Power to address billing,
objectives of pilot project, ownership of equipment, possible
outcomes, etc.
– Begin pilots in 2010
– Sign boards to be installed at each location announcing pilot and
pointing to information & questionnaire on website.
– Publish results of pilots and share information with customers
and others; determination to be made moving forward.
– Evaluate performance, review feedback, consider tariff rates for
LEDs based on information learned from pilots. No firm dates
established for LED implementation in Delmarva Power.
