has been completed.
EXECUTIVE SUMMARY:
The existing HPS streetlights used throughout North America are now being replaced
by new lighting technologies such as LED. The main driver for the conversion to these
new types of streetlights is an immediate utilities and maintenance cost reduction,
environmental benefits and future cost avoidance associated with projected utility rate
increases. Whitby is responsible for a streetlight system which is comprised of 11,600
streetlights all of which are high pressure sodium. As an emerging technology, there
are many manufacturers, distributors and agents all promoting LED technology and
therefore it is important that the luminaire specifications are independently verified.
The Department is recommending that an electrical consultant be engaged to provide
professional assistance starting with the technical selection and prequalification of
LED luminaires. When confirmed, the specifics of LED technology will be incorporated
into the Town’s Streetlight Design Guideline as a replacement for HPS. To
demonstrate LED technology and its application for streetlights, a pilot/demonstration
project is recommended for a section of Watson Street between Victoria and Charles
Street. The Department intends to provide Council with further updates and
recommendation reports on the selection of specific LED products and on the
milestones associated with the proposed streetlight conversion project.

ORIGIN:
Public Works Department Report 10-12 originates from within the Department.
4.0
BACKGROUND:
4.1 Overview
Streetlighting is provided on arterial, collector and local roads to help motorists remain
on the roadway and for the detection of obstacles within and beyond the range of
vehicle headlights. Streetlights allow for quick, accurate and comfortable visibility at
night to safeguard, facilitate and encourage vehicular and pedestrian traffic.
The Town of Whitby presently manages the municipal streetlight system on Town and
Regional roadways. The system is comprised of approximately 11,600 luminaries
which vary in terms of wattage and style (Refer to Attachment No 1). Of the 11,600
streetlights approximately 1,480 are on Regional roadways and will be the subject of
OPS-167.2
Report to: Operations Committee
Report No.: PW 10-12
Page 3 of 13
future reports as identified previously through Report PW 34-11. Different wattages are
required for either a specific application and/or profile of roadway whereas styles are
selected to suit development or aesthetic objectives. The most common style of
luminaries used for streetlighting in Whitby are: cobra head, decorative coach, and
square-pak (Refer to Attachment No 2).
In 2010, the Provincial Government advised that the cost of electricity in Ontario will be
increasing by almost 50 percent over the next 5 years. This hydro increase alone
would increase streetlight utilities costs from a 2010 budget value of $1,054,500 to a
2015 budget value of $1,581,750. The 2011 streetlight budget for operating (including
hydro) and major capital repair was $1,486,069 while the proposed 2012 budget for
operating and major capital repair is $1,671,508.
This report focuses on the implications and incorporation of new technology
specifically for the streetlight system and does not deal with any other types of outdoor
lighting owned by the municipality such as sports fields, parking lots, building exteriors
and pathways.
4.2 Streetlight Technology
Present day streetlighting is based on a high intensity discharge light source with high
pressure sodium (HPS) being the most widely used. High pressure sodium lights were
developed in the 1960’s and until recently, was considered the best light source
available in terms of energy efficiency and optical controllability. High pressure
sodium however, emits a yellowish light that has very poor colour rendering, meaning
that colours and objects are not easily identifiable.
Recent advances in streetlighting technology have resulted in the introduction of new
and more energy efficient lighting sources in the market place. The savings associated
with these technologies ranges upwards of 50 percent as compared to HPS. Of these
new technologies, induction and; light emitting diode (LED) have been considered as a
suitable replacement for HPS streetlights. The following paragraphs introduce the
technology of both light types and a further discussion regarding their effectiveness is
presented in Section 5.2 of this report.
Induction lighting was developed some 30 years ago and is based on a design similar
to that of a fluorescent lamp (Refer to Attachment No 3). This type of lighting
consists of an inductively coupled closed loop style fluorescent lamp and high
frequency ballast. Magnetic induction is used to power the lamp instead of electrodes
at either end. The lack of electrodes results in longer bulb life than that of HPS.
Induction also provides a white light and good colour rendering. The useable rated life
of an induction light is more typically between 60,000 – 70,000 hours (16.5 years) as
compared to the 100,000 hours (23.5years) being promoted.
OPS-167.3
Report to: Operations Committee
Report No.: PW 10-12
Page 4 of 13
One of the major drawbacks associated with induction lighting is its limited optical
control due to the large size of the light source. The direction and output of the light
relies on the reflectivity design within the luminaire. Manufacturers have indicated that
there is little research and development being conducted on this light source and
therefore future technological improvements are doubtful.
LED lighting is based on a solid state system consisting of a series of tiny chips fit into
an electric circuit (Refer to Attachment No 3). The chips are lit by the movement of
the electrons in a semiconductor material. In recent years, white coloured LED’s have
entered the marketplace joining the low wattage and coloured LED’s which have been
in widespread use for decades. The white LED‘s have good colour rendering. The
colour range for LED lights can vary from blue to white, and is measured in Kelvins.
The preferred Kelvin for streetlights ranges from 3,500 to 5,000 K with 4,300 K being
the colour temperature of moonlight.
The 3 main benefits of LED for streetlighting applications are that they are low
wattage, have great optical control and long life. LED’s can be aimed to provide light
only where it is needed and do not create an area of excess light below the fixture like
that of HPS and induction. The average useable rated life of a LED is estimated at
70,000 hours with some being as high as 100,000 hours. Feedback from other
municipalities and suppliers has revealed that, at the present time, the lower wattage
LED streetlights are the most efficient and least costly. The efficiency of the higher
wattage LED is expected to increase in the near future as technological improvements
in LEDs are continuing at a rapid pace. The municipality has had a positive
experience with LED lights as the traffic signals throughout the Region of Durham
were converted to LED in 2008. Energy savings of 69 % have been achieved as a
result of the switch. LED’s generate significant heat and so the fixture itself is designed
to dissipate this excess heat. Failure to due so will reduce the life of the LED and
results in premature failure. It is for this reason that replacement of the complete
luminaire is undertaken and why retrofit kits have not yet been widely utilized.
4. 3 Streetlighting Standards and Authorities
All streetlight installations throughout North America are designed in accordance with
the RP-8 American National Standard Practice for Roadway Lighting. The RP-8
standard was developed by the Illuminating Engineering Society (IESNA) of North
America which is the technical authority on lighting. This standard defines the
photometric criteria required for lighting various road profiles to ensure quick, accurate
and comfortable seeing at night.
In Whitby, the streetlight system is designed and installed in accordance with the Town
of Whitby Streetlight Design Guide. This document specifies that streetlights will be
designed to the RP-8 American National Standard Practice for Roadway Lighting. The
Design Guide also outlines the specifications and details for the connections,
OPS-167.4

trenching, wiring, poles, brackets and fixtures. Included in the document is an
approved material listing for each of the streetlight components including pole, bracket
and luminaire.
In 2009, the Town of Whitby Planning Department, through Report No PL-117-09,
brought forward “Lighting Guidelines” for new development applications. Due to
technology changes in the lighting industry, the Town of Whitby along with the other
Regional municipalities engaged a consultant to develop guidelines for lighting of
private property. The guidelines were intended to mitigate inefficient energy
consumption, over-lighting and light trespass. The guiding standards included:





Use of full cut off fixtures so that the light rays emitted are projected below the
horizontal plane
Positioning of lights to provide uniform distribution and avoidance of overillumination that make adjacent areas seem darker
Encourage the conservation of energy
Lamps are located to avoid directing light to neighbouring properties
Except where lighting is strictly ornamental, photometric performance (the
glare, intensity and uniformity of the light produced) is more important that
aesthetics
In 2011, the IESNA along with the International Dark-Sky Association developed a
Model Lighting Ordinance (MLO) as a guide to assist municipalities develop their
outdoor lighting standards. The MLO uses the IESNA’s new TM-15-11 “BUG”
(Backlight, Uplight and Glare) classification of outdoor lighting fixtures to ensure that
only well-shielded fixtures are used. Application of the MLO and the Town’s Lighting
Guidelines will result in privately owned lighting being more efficient and
environmentally responsible than the municipal streetlight system. Having said this,
the IESNA does not recommend that the MLO be applied directly to streetlighting
because of the precise calculations involved.
Instead the MLO contains a
recommended streetlighting ordinance which advises that ornamental streetlights
(coach style) should not exceed a BUG rating of 1. All other streetlights (cobra head
and square-pak) shall have a BUG rating of 0 resulting in no light being emitted above
90 degrees. Since streetlighting is one of the world’s largest causes of artificial
skyglow which is defined as the illumination of the night sky or parts of it, it is important
that future streetlighting initiatives meet the MLO.
The City of Toronto created a separate agency, the Toronto Atmospheric Fund, to
promote climate stabilization through greenhouse gas emission reduction, local air
quality initiatives, energy conservation and efficiency, and public education. The
Toronto Atmospheric Fund (TAF) has worked to promote new energy efficient
streetlighting technologies and in particular LED lighting. To further support LED
initiatives, TAF has just developed a protocol to assist municipalities in selecting,
monitoring and evaluating the performance of LED products used in pilot or larger
scale projects.

Staff has also started to attend the quarterly meetings of the Ontario Municipal
Streetlighting Focus Group (OMSLFC). This group is made up of representatives from
local municipalities across the province who meets to share information about
streetlight initiatives and technology. Although the OMSLFC group has not developed
any standards of their own, they have endorsed LED lighting as the preferred
streetlight technology for streetlight applications. This group also supports the
initiatives, standard and protocol as developed by TAF, IESNA and the International
Dark-Sky Association.
5.0
DISCUSSION/OPTIONS:
5.1 Jurisdictional Review
Many municipalities have started or are now considering upgrading their streetlight
system from HPS to one of the new technologies. The main drivers for this change are
to: reduce the system operating costs, avoid future projected utility cost increases and
for environmental reasons such as reduced energy consumption. For either induction
or LED technology, there is a significant amount of information available on the
internet and from a multitude of suppliers and/or manufacturers sales representatives.
To confirm the many claims made by manufacturers and their representatives, some
government agencies and institutions (universities and hospitals) have piloted these
different lighting technologies. Many of these same agencies and institutions have
also engaged electrical experts, either independently or through their local utilities, to
assist in determining which of the new technologies is best. The importance of
independently confirming the manufacturer’s specifications was confirmed through
these pilot projects as in some instances the actual product performance was over
stated and the results did not always match the claims. A jurisdictional review of
streetlighting projects by other government agencies and institutions is outlined in
Attachment No 4.
5.2 Induction versus LED for Streetlights
Induction lighting was promoted as an early HPS conversion choice by the Local
Authority Services Ltd (a division of the Association of Municipalities of Ontario) in
2008. To date, the Department is aware of only two smaller Ontario municipalities who
have retrofitted their streetlight system with induction lighting. Although energy savings
were achieved, there have been problems primarily with optical control and a lack of
light uniformity. This experience confirms the information received from other
municipalities who have piloted induction lights. These municipalities reported that
optical control was a significant problem and that the light distribution was not
adequate to meet the roadway lighting standard of RP-8 in some instances. Based on
the experiences of other municipalities to meet the RP-8 standard with induction
OPS-167.6
Report to: Operations Committee
Report No.: PW 10-12
Page 7 of 13
lighting, existing pole spacing in some instances would have to be reduced and more
infrastructure added. Therefore, retrofitting the existing HPS lights with induction lights
was not conducive to a 1 to 1 exchange. One municipality who piloted Induction lights
in their downtown commercial area also reported that light spillage was a problem with
the excess light being reflected off of the adjacent buildings in the immediate vicinity of
the luminaire. Those municipalities who tested induction lighting did not end up
selecting or pursuing induction technology beyond this stage. A photometric
comparison between HPS and induction lighting is shown on Attachment No 5. For
the reasons identified above, induction lighting is not recommended as an alternative
to HPS for streetlighting for the Town of Whitby.
LED lighting is the preferred alternative to HPS for a number of reasons. Optical
control is one of its biggest advantages as the LED fixture can be designed to direct
light to exactly where it is needed, thereby avoiding dark spots and light wastage. LED
lighting can meet RP-8 standards and has been found to be compatible to enable a 1
to 1 exchange with existing HPS lights. Based on the pilot studies, an operational
savings of 50 % can be anticipated. Besides reduced energy costs, their low
maintenance characteristics allow for a reduction in other operating costs associated
with bulb replacement and lens cleaning. LED luminaries, with the exception of the
decorative Coach style are dark-sky compliant, therefore eliminating sky glow.
Currently, the City of Welland is in the process of converting their streetlights from
HPS to LED, and the City of Mississauga is planning for their LED streetlight
conversion program starting in 2012. The Town of Uxbridge recently installed 2
different styles of LED lights in their downtown, and the City of Oshawa has specified
LED streetlights for all new developments. Most recently, the Town of Oakville has
reported that they will be installing LED streetlights on new and retrofit projects.
Based on the success of the LED pilot programs in other Ontario municipalities and on
the information provided through TAF and the Streetlight Focus Group, the
Department is recommending that Whitby adopt LED technology for its streetlights as
an alternative to HPS.
Replacement of the HPS streetlights with LED will result in a number of environmental
benefits. LED lights have reduced energy consumption which creates offsetting
environmental benefits associated with reduced power production and associated byproducts including carbon and sulphur dioxide. Unlike HPS bulbs, LED lights do not
contain mercury, so there is no associated hazardous material designation which
requires special disposal measures. The move towards dark sky compliance and
minimizing the impact of skyglow has environmental benefits for wildlife migration and
behaviour.
To illustrate the appearance of LED lights on a local street, the Department is
recommending that a demonstration project be initiated. Watson Street from Victoria
to Charles Street is the recommended site as there is a combination of high density
residential, institutional and industrial uses fronting this section of the street (Refer to
Attachment No 6). There are a total of eleven (11) - 100 watt HPS cobra head
OPS-167.7
Report to: Operations Committee
Report No.: PW 10-12
Page 8 of 13
luminaires that could be switched out to 65 -70 Watt LED as early as March. The
property owners along this street will be notified of this change prior to the
demonstration project being initiated and their feedback requested. With so many
municipalities having undertaken LED pilot projects, the Department felt it important to
showcase a street featuring the lower wattage LED lights as a comparison to HPS.
The maximum cost of the LED demonstration project is estimated at $8,500.00 to
purchase and install the LED luminaires. The LED fixtures that are proposed to be
used for this demonstration will be provided by Philips Lumex, the manufacturer who
supplied the LED luminaries to the Town of Ajax and Township of Uxbridge.
5.3 Design and Product Requirements
Whitby’s streetlight system is composed of luminaires of different wattages and styles,
different pole styles and heights, different luminaire mounting systems and heights, all
of which are designed to fit and/or light different road profiles. Over and above these
existing conditions, there are also many different LED configurations, styles and
specifications that must be considered and evaluated. New construction or complete
capital replacement is easier, as the streetlight infrastructure would be designed
specifically for LED lighting from the start. For retrofitting situations however,
engineering calculations are required in order to ensure that the replacement LED
luminaire is configured to meet RP-8. In order to address the different design and
certification issues, it is recommended that a terms of reference be developed in order
to engage a consultant to assist the Department with the following electrical
engineering undertakings:




adapt the TAF protocol to develop LED streetlight standards and specifications for
the Town of Whitby
review the Town’s streetlighting system in order to develop standard street and
photometric profiles for prequalification purposes (potential suppliers need to know
the photometric profiles to determine the LED configuration within the luminarie)
to assist in evaluating and prequalifying bids for the supply of LED luminaires
including independent electrical testing
to update and incorporate LED streetlight information into the current Streetlight
Design Guide
In the past, Whitby Hydro Energy Services has provided engineering services to the
Department including the development of the Streetlight Design Guide. This practice
however, has ceased due to the affiliate agreement administered by the Ontario
Energy Board. Having said this, Whitby Hydro is aware of and has confirmed that the
Department’s proposed phased approach towards engaging a consultant and
incorporating LED’s into the streetlight system is logical. Whitby Hydro will be
involved in the grant application process due to the Provincial mandate to reduce
energy consumption.

5.4 New Development/Capital Streetlight System Replacement
When the Streetlight Design Guide is updated, it would be the Department’s intent to
incorporate LEDs into all new developments. Developers would be advised prior to the
submission of electrical engineering drawings that the streetlight design is to
incorporate LED technology. Developers currently submitting plans would also be
advised of the Town’s intent to switch to LED technology. In these situations if the
design is still in the plan stage by the time the Streetlight Design Guide has been
finalized, the electrical design would be modified to incorporate LED technology.
Changing the design at this stage and installing LED’s of all wattages, will eliminate
the need for the municipality to spend future funds to retrofit the luminaires.
For capital projects that involve replacing the entire streetlight system, the
Department’s intent would be to base the design on LED lighting. There is one such
project currently on the books involving the replacement of fibreglass poles and
luminaires in the Bluegrass Meadows subdivision. The design is currently being
undertaken and the Department is recommending the deferral of this project until such
time as the prequalification process for the LED luminaries has been completed.
5.5 Phased Conversion of Existing Streetlights to LED
At the present time, LED technology is best at the wattages (100 or less) used to light
local streets although it is also available in the higher wattages used for collector and
arterial roadways. For the higher wattage luminaires, LED technology is anticipated to
greatly improve over the next several years resulting in a reduced fixture size as well
as cost. To replace the Town’s 11,600 streetlights over a short period of time may not
be the most practical approach. This is based on anticipated future technological
improvements and the inability to undertake all of the work at one time. Therefore a
phased approach will be developed starting with the lower wattage luminaires.
Phasing will also need to take in to account the different styles of luminaires used
throughout Town. The cobra head is the most common luminaire used in Whitby and
it also happens to be the most common luminaire in the LED market. The decorative
coach luminaire is also available in an LED fixture but it is not dark sky compliant and
is more expensive than the cobra head. As such, most municipalities are focusing on
converting the cobra head fixtures and opting to leave the decorative coach luminaires
to the last phase. The logic behind this is similar to that identified for the higher
wattages in that future technological changes and volume of use may reduce the
current luminaire cost. With respect to the square-pak luminaire, its performance is
similar to that of the cobra head. Based on initial conversations with suppliers it
appears that the square-pak luminaire can be switched out with a cobra head with
some mounting arm modification. Making this change would ultimately result in 2
styles of streetlight fixtures used throughout Whitby namely the cobra head and the
decorative coach. The conversion phasing would also take into account fixture style,
OPS-167.9
Report to: Operations Committee
Report No.: PW 10-12
Page 10 of 13
with the cobra head being changed out first. Dependant upon the consultant feedback
on the square-pak conversion to cobra head, these lights could be included in the
initial conversion phasing as well.
On a secondary level, changing the lighting technology also presents an opportunity to
standardize the luminaire styles by street classification or location for new
developments, capital projects and retrofit programs. Of the 3 styles of luminaire used
in Whitby, the Department would focus on the cobra head and the decorative coach
light. For example, the cobra head could be used for all local, collector and arterial
roads while the decorative coach would be used for special areas such as the
downtown, heritage and business districts. Input from the Planning Department would
be obtained in identifying the desired areas of Town or special decorative lighting
areas so that this change can be incorporated into the conversion program as well.
Once the LED luminaries have been prequalified, the Department would work with the
electrical consultant to develop a LED streetlight replacement program based on many
of the parameters previously identified including HPS streetlight bulb relamping
program. The Department would report back to Council with the details of the
conversion program and financing later this year.
As the Department moves forward with the change in technology, staff will continue to
liaise with Whitby Hydro Energy Corporation and the other municipalities within the
Ontario Municipal Streetlighting Focus Group.

CONSIDERATIONS:
A.
PUBLIC
The adjacent property owners and the general public will be encouraged to
provide feedback on the Watson Street LED streetlight demonstration project
through a survey and feed back form on the Town’s web page.
B.
FINANCIAL
The Town’s 2011 streetlight budget for operating and major capital was
$1,486,069 and the proposed 2012 draft budget is $1,671,508. Of the draft 2012
budget, $1,254,835 relates to hydro costs which has increased by $126,003 over
the 2011 budget, due to global adjustments and increased rates. Given the
OPS-167.10
Report to: Operations Committee
Report No.: PW 10-12
Page 11 of 13
Provinces anticipated continued increase in utilities rates, the financial incentive
is based on reduced energy costs as well as future cost avoidance.
The estimated cost for the supply and installation of replacement LED streetlights
can range from $400 to $600 each for cobra head and upwards of $1,000 each
for the decorative coach luminaire. Assuming a $600/luminarire cost, the total
capital cost for replacing the 4,629 cobra head luminaires would be $2,777,400.
Exact energy savings will not be able to be calculated until the specific luminaires
and associated wattages have been determined for each road profile. The
Department however, has estimated that the replacement of the 4,629 lower
wattage (70/100 watt) HPS cobra heads with LED luminaries on local streets
would result in the financial lifecycle costs as summarized in the table below.

Lifecycle Savings
* Lifecycle savings are calculated at 9% per annum for energy until 2015 and 3 %
per annum for the balance. Maintenance savings are calculated at 3% per annum
**These calculations are based on the higher fixture price and the lower lifecycle.
Therefore as technology improves and LED’s are more widely utilized the savings
are anticipated to be greater.
***Energy savings of LEDs to that of HPS have been documented to be upwards
to 50%
Based on the lifecycle savings in the above chart the payback period is
anticipated to be 10.13 years. With future technological advances and lower unit
costs greater savings can be anticipated, for example, if the life cycle increases to
20 years and the cost decreases to $400 per fixture the payback is calculated to
OPS-167.11
Report to: Operations Committee
Report No.: PW 10-12
Page 12 of 13
be 6.3 years. Factoring in any potential grants or provincial incentives, the
payback period could be further reduced.
Due to future technological advances the calculations for the other types and
higher wattage luminaires would be undertaken once the consultant has assisted
the Department with the prequalification process. The estimated upset cost for
having an electrical consultant complete the required work is set at $50,000.00.
These costs will be funded from one time capital reserves.
As part of the report to Council on the LED conversion program and the
Bluegrass Meadows streetlight replacement project the Department will also
report on the status of any funding opportunities that may exist to reduce the
overall project costs.
C.
IMPACT ON & INPUT FROM OTHER DEPARTMENTS/SOURCES
The Planning Department would be requested to assist in identifying the desired
areas of Town where decorative style lighting would be installed as compared to
the standard cobra head fixture. Whitby Hydro Energy Corporation would be
involved with the energy savings calculations and assisting with grant
opportunities.
D.
CORPORATE AND/OR DEPARTMENT STRATEGIC PRIORITIES
The change in streetlight technology is consistent with the corporate strategic
objectives of improving municipal and community infrastructure, promoting the
conservation and management of natural resources and to work to ensure that
municipal services are cost effective.
8.0
SUMMARY AND CONCLUSION
The Department has recommended LED technology be pursued as a replacement for
the existing HPS streetlights used throughout the municipality. Conversion or
incorporation of LED technology into the streetlight system will result in an immediate
utilities and maintenance cost reduction, environmental benefits and future cost
avoidance associated with projected utility rate increases. LED street lights result in a
more natural light and provide for better colour definition than the existing yellow HPS
streetlight. LED lights also allow for a 1:1 conversion for the existing streetlights
meaning that the existing pole locations will not need to be adjusted.

Jurisdictional Review of Street Light Projects
City of Burlington, ON
In 2009, the City of Burlington pursued a pilot to retrofit the lighting at City Hall,
including in the parking garage. Current exterior lighting fixtures consist of a
combination of 175 watt and 100 watt mercury vapour and metal halide lamps.
There are 26 wall-mounted fixtures, 19 bollards and 30 low-bay garage fixtures
that were replaced with lower-wattage LED fixtures. The City is also exploring
the use of adaptive controls in the parking garage.
City of Edmonton, Alberta
The City of Edmonton has ordered 2,580 Satellite LED luminaries from LED
Roadway Lighting for a mixed project of replacement and new roadway lighting.
According to LEDs magazine, “The city projects that the SSL project will deliver
$2.6 million in energy savings over the high-pressure sodium (HPS) fixtures that
are currently in use. Over the 20 year period, the city projects a reduction of
12,880 tonnes of greenhouse gas emissions. Moreover the aggregate electricity
savings total 16,000,000 kWh.”
City of Hamilton, Ontario
In 2009, the City of Hamilton launched a pilot study for the installation of four
LED street lights in cooperation with LightSavers, to research and test the results
of the pilot. In 2011, a report on the pilot was released. The project proved that
LED streetlights can meet North American standards for roadway illumination.
Despite moving from a 130 watt HPS fixture down to a 59 Watt LED, illuminance
levels on the road actually increased by about 50%. As well, the report identified
the need for surge protection in LED fixtures as a requirement when purchasing
the lamps. Hamilton is now installing LED fixtures in new developments.
City of Mississauga, Ontario
The City of Mississauga has recently closed a Request for Pre-Qualifications for
LED streetlights. Mississauga, which has been a participant in the LightSavers
program, owns and operates approximately 45,000 High Pressure Sodium
streetlights, and is planning to convert the majority of these lights to LEDs.
City of North Bay, Ontario
In 2011, the City of North Bay issued a Request for Proposals (RFP) for 5,567
LED streetlights after a comprehensive evaluation of energy efficient streetlights.
North Bay plans to replace all of the city’s existing streetlights with LED fixtures
having reviews LED, induction, and other technologies.

City of Red Deer, Alberta
In early 2011, the City of Red Deer announced that the city will install LED
lighting into all new subdivisions on a go-forward basis. This decision came
forward after a successful three month LED street light pilot study. The pilot
study looked at the factors of lighting level, electricity use and life cycle cost.
City of Toronto, Ontario
Toronto Hydro’s Adaptive Lamp Management Program (ALAMP) was launched
to research, test and implement new street light technology and controls, find the
most energy efficient and cost efficient street lighting solution for the City of
Toronto that meets the Illumination Engineering Society of North America
(IESNA) RP8 Roadway Lighting guideline, and ensure recommended street
lighting solutions enhance public safety and streetscape ambiance. Toronto
Hydro has installed LED lighting into four Toronto locations for testing and
research.
In 2010, Exhibition Place replaced approximately 70 high pressure sodium lights
along its pedestrian walkway with lower-wattage LED products. Adaptive lighting
controls were also installed, allowing the lights to be dimmed when the pathway
is not in use.
City of Welland, Ontario
In 2007, the City of Welland began piloting the use of LED lighting as a retrofit
option to their HPS street lights. Due to the success of the Welland LED pilot
projects, in 2011, the city approved the conversion of their entire city owned
outdoor lighting network to LED. The proposed program will achieve a $2.5
million in savings over 15 years.
Nova Scotia, Canada
Nova Scotia indicated in April 2011, that the province would introduce legislation
to mandate the use of energy-efficient lighting across the province. Nova Scotia
will become the only province or state in North America to ensure only LED
streetlights are used on its roadways. Research by the province and Nova
Scotia Power shows that switching to LED lights will create energy savings of
more then 50 per cent. When combined with reduced maintenance costs, the
estimated annual savings are about $18 million. It will also reduce greenhouse
gas emissions by more than 30,000 tons, and save a half kilogram of mercury
each year. There are about 120,000 roadway lights in Nova Scotia. Most are
owned and operated by Nova Scotia Power, with about 10 per cent that belong to
municipalities. The cost of converting to LED lighting is estimated at about $100
million.

Town of Penetanguishene, Ontario
The Town retrofitted a total of 278 of their existing 250W mercury street lights
with 104W LED (light emitting diode) luminaries. The resultant energy savings
was estimated to be 63.6%. Mercury lamps represent 50 year old technology
and are no longer available fore street lighting applications.
City of Fredericton, New Brunswick
In 2009, the City of Fredericton installed LED street light fixtures from 11 different
manufactures at 20 locations to evaluate their performance against HPS street
lights. The study results confirmed that the luminance of some LED fixtures
exceeded RP8 and that there was a power savings between 20-45% as
compared to HPS.
City of Vaughan, Ontario
The City of Vaughan have converted 1,800 HPS street lights to LED in industrial
areas and residential streets which are considered as one way in and out. Staff
reported that they were able to do a 1 to 1 conversion.
Town of Ajax, Ontario
The Town of Ajax have installed 7 LED lights on Falby Court and for a new
traffic circle in late 2010.
Township of Uxbridge, Ontario
The Township of Uxbridge have replaced existing HPS streetlights with new
decorative LED streetlights on Toronto and Brock Streets through their downtown
core. As well, LED cobrahead luminaries were installed at a new traffic round-about on Brock Street West. Staff from Uxbridge confirmed that they along with
the downtown merchants they were very pleased with the LED lights in terms of
appearance and function.
