EXECUTIVE SUMMARY
To calculate the feasibility of an Energy Conservation Project,
the most important historical and predictive information is the
Cost of Electricity. In this effort, historical information obtained
from the City has been utilized to predict the future trend of this
cost starting from the year-end 2015 cost of $0.08 23.
Annual Average Operation Time for Street Lights is another
factor that is important in calculating consumption. According to
reports obtained from City of Lights, is 4,257 hours per year.
Next step is to analyze he public street lighting inventory. Tbilisi outdoor lighting inventory is
comprised predominately of High Pressure Sodium (HPS) and Metal Halide (MH), which are inefficient
conventional street lights, consuming significant amount of energy and carry a high cost to own and
operate. Below is a summary of the current inventory and its cost to the city based on year-end 2015
Cost of Electricity and Annual Average Operation Time for Street Lights
Energy Expenses has been calculated based on the current luminaire inventory and its consumption
cost to the city based on year-end 2015 Cost of Electricity and Annual Average Operation Time for
Street Lights. The calculation in this table assumes that all lights were 100% operational, (as they
should be) throughout the year. This is what we want to achieve with LED lighting.
Maintenance Expense was given as 2014 budget for the City of Lights Company, whose sole
responsibility is to install and maintain outdoor lighting in the city. Therefore complete budget of
$3,577,318 was distributed per luminaire based on their consumption level. This will later help in
calculating savings when upgraded to LED lighting.

Identifying the right LED Luminaires
The correct technical method to modernize lighting in the City should be by conducting a lighting study
by feeding below data for the entire city into a professional lighting program.
- Roadway Maps
- Roadway Types
- Roadway Widths
- Traffic Load on Roadways
- Pole Distances
- Pole Heights
- Luminaire Overhang
- Luminaire Elevation Angle
- Type of Luminaires
- Wattage of Luminaires
Information obtained so far has been limited to Type and Wattage of existing luminaires and therefore
an alternative method had to be utilized to identify the LED upgrade structure.
Matching LED luminaires to existing HID luminaires by MEAN lumen output is that method and it is a
tedious task, especially considering rapid advances in LED technologies.
I’ve pointed out rapid development in LED technologies, because OPTICA Series LED Luminaires are the
most up-to-date solution to Street Lighting with average 115 lumens per LED watts. By using a high
Efficacy luminaire, we can utilize lower wattage LEDs and therefore increase savings much more.
Naturally the luminaire has to be also priced feasibly.
So, we match the MEAN lumen output of each type of luminaire to determine the Wattage of LED
luminaire that can replace one-to-one the existing HID luminaire. Below table makes this comparison
and determines the LED wattage applicable.
An example would be 70W HPS vs 25W OPTICA LED
- The effective mean lumens of a 70W HPS is about 2300lm.
- This can be easily replaced by a 25W OPTICA LED driving 2875 lumens at 115lm/W.

EXISTING OUTDOOR LIGHTING IN THE CITY
The existing public street lighting in Tbilisi is comprised predominately of High Pressure Sodium (HPS)
and Metal Halide (MH). These mostly inefficient conventional street lights consume significant amount
of energy and carry a high cost to own and operate. They contribute to a number of environmental
hazards and are very toxic because they contain highly levels of mercury.
In addition, the light levels associated with these energy savers was determined to be unsafe and
inappropriate for the task environment. In many ways, the reduced safety and new exposure to
accidents and incidents resulting from poorly lit environments compounds an already problematic
infrastructure.
Street lights installed in all parts of Tbilisi are powered by the existing electrical grid electricity. Billing
arrangement is based on consumption and charged while lights are operational.
High Pressure Sodium Streetlights
High pressure sodium lamps (HPS) tend to look yellow and provide poor color rendering. HPS lamps
were developed in 1968 as energy-efficient sources for exterior, security, and industrial lighting
applications and are particularly prevalent in street lighting. Standard HPS lamps produce a golden
(yellow/orange) light. Due to their poor color-rendering their use is limited to outdoor and industrial
applications. HPS lamps generally contain 10 to 50 mg of mercury. A small percentage contains more
than 50 mg of mercury.
Annual Average Operation Time for Street Lights is measured to be 11 hours and 39 minutes per day
or 4,257 hours per year.
Cost of Electricity for Street Lighting has increased from
$0.0380 in 2010 to $0.0686 in 2014 and over $0.0823 in
2015. Considering this trend in the past 5 years, an
annual 2.5% increase is predicted in overall electric
expenses and it is also expected that the same
inflationary trend can be observed in maintenance
expenses.

LED OUTDOOR LIGHTING – A Solution to the Problem
The primary appeal of LED street lighting is energy efficiency compared to conventional street lighting
such as sodium and mercury lights. BLUE ARROW LED streetlights incorporate best in class components,
are warranted for 10 years and leverage the most recent technological advances in diode and driver
technology pushing efficiencies above common LED fixtures in the marketplace. Hence, BLUE ARROW
LED lights can be an advantageous fix for the problems being faced by the current road lighting
systems. It can reduce energy costs up to 75% depending on the type and class of LED light being used
and at the same time it can provide more luminance and a greater longevity compared to these
conventional lights. From an economic perspective, procuring and installing LED lights is beneficial for
Tbilisi as it will result in reduced consumption due to increased energy efficiency.
Important Points to Consider when Selecting an LED Luminaire
There is an increased pressure to adopt more sustainable technologies and therefore the rate of
technological innovation has increased rapidly. This rapid technological advancement creates drastic
differences in technology with LED luminaires with major disparities in performances across fixtures.
Combined with the thousands of new LED lighting manufacturers emerging over the past 5 years, it
makes so much more important to evaluate and verify technical capabilities of LED lighting options.
This trend has made it imperative for public sector institutions to qualify luminaires based on data
measured and quantified by industry recognized and approved methodologies. The only way to
determine the suitability of a particular luminaire for the application is to:
• Identify and set illumination requirements – These requirements should be based on internationally
recognized illumination standards such as IESNA RP-8 and RP-20.
• Identify placements – Luminaires offer different distribution patterns and performance which respond
very differently based on their placements. For example, in a roadway or parking lot environment it is
imperative to know mounting heights, distances between poles, speculative matter of the pavement
surface, etc. These parameters must be identified in order to determine how a luminaire will perform
in the given environment. Without these, any form of replacement recommendation is nothing more
than a guess.
• Obtain credible IES files – IES files are used by lighting designers, consultants and engineers. They are
used in creating lighting designs and evaluating the actual performance of a luminaire, and can be used
to determine how a luminaire will perform in a given environment. To ensure the accuracy of the data
contained in an IES file, it must be created by a third party, NV LAP accredited laboratory, in
accordance with international testing standards (i.e. LM-79). If the provider of an IES file cannot
demonstrate that it was created under these conditions, its legitimacy should be in question.

update 10/2/2016 2:43 PM 9 | P a g e
• Obtain ISTMT reports – IN-SITU Temperature Measurement Testing must be performed by an
accredited third party. This testing is the measurement of the LED source case temperature within the
LED system (luminaire or lamp) while it is operating in its designed position and or environment (In
"SITUation"). The measurement is performed at the temperature measurement point (Tc Point)
indicated by the LED package manufacturer. In other words, the highest junction temperature is
identified. This is important as thermal performances directly affect the longevity and reliability of an
LED fixture. Once known, this value can be used as an input in TM-21 Calculations which accurately
determine LED fixture lifecycles and light loss factors.
• Perform TM-21 Calculations – This is an approved method making useful LED lifetime projections. It
proves a recommendation for projecting long term lumen maintenance of LED light sources using LM-
80-08 lumen maintenance data. The standards apply to lifetime projection of LED package, array or
module alone. The results can then be used to interpolate the lifetime of an LED source within a
system (luminaire or integrated lamp) using the In-SITU LED source case temperature. This is extremely
critical when validating life expectancy of a luminaire and performing photometric calculations. When
performing photometric calculations, it is proper to create designs based on how a luminaire will
perform at end of life. This ensures that when designing to meet a specific lighting requirement the
required levels will be adhered to right until end of life of the luminaire. In order to determine how a
fixture will perform at a certain point in time TM-21 calculations must be performed.
• Create an Engineered Photometric Report – Utilizing credible IES files, accurate roadway and pole
parameters, and accurate Light Loss Factors (obtained by TM-21 calculations) a photometric report
should be created, using industry standard lighting software, such as AGI32 or DIALUX, to see if the
recommended luminaire is capable of meeting the identified illumination requirements. When
constructed using all of the identified criteria the results will be extremely accurate.
• Evaluate performance in the field – Once a design has been created that meets all criteria, the
remaining step is to deploy the luminaires in the field. As long as all criteria listed above have been
met, there should be very little discrepancy between field performances and results depicted in the
photometric report.
Light Level Standards
It is always the intent to comply with international light level recommendations. Roadways are
classified based on set criteria identified by the IESNA group. Based on these classifications, each
roadway category is further subdivided based on the potential pedestrian conflict levels. When all of
these factors are observed a roadway will have a single classification. Based on this classification there
are associated light level recommendations that are ideally to be followed. These recommended
values are defined within the RP-8 standard.

update 10/2/2016 2:43 PM 10 | P a g e
Below is a condensed chart of these values compared to values measured in Tbilisi
Ideal Selection Method of LED Luminaires
As it can be observed from the measurements taken within the city, there is an opportunity to correct
lighting levels to upgrade city street lighting levels to international standards. For this purpose we
suggest a detailed categorization of city roadways and areas where correct roadway measurements are
gathered.
When evaluating the city inventory, we see that majority of the fixtures are low quality High Pressure
Sodium and Metal Halide luminaries. Comparing the lumen output of these types of luminaires versus
our OPTICA Series LED Luminaires, we can make an educated estimate of the correct wattage of LED
luminaire to replace an existing HID fixture.
The most accurate method in determining the right LED luminaire to be used in any location is to have
the full layout of the location. By that we mean below information gathered according to IESNA
classification, as defined within the RP-8 standard:
• Type of Luminaire
• Roadway Type
• Traffic Flow
• Roadway Width
• Pole Distance

Once this necessary data is obtained, BLUE ARROW would be able to prepare a photometric report where
suitable fixtures would be laid out for the various roadways throughout Tbilisi, selected to meet RP-8
values. This detailed data collection can be achieved during the product manufacturing process of
project implementation, and the adjusted layout may slightly alter the quantity of suggested wattages
of the LED luminaires in this report.
In some instances, based on existing infrastructure and pole spacing, it is not practical to achieve RP-8
values. This is fairly common in instances where infrastructure has evolved over many years. While a
future option could be to erect additional light poles in an effort to achieve RP-8 values, it is
recommended that this be a later initiative. In instances where limitations with existing infrastructure
prohibit achieving RP-8 values, the goal will be to increase light levels as close to RP-8 values, while still
deriving significant energy and maintenance savings.
Preliminary Selection of LED Luminaires
Lumen output of each bulb type should also be considered selecting a comparable LED luminaire.
Initial lumens of a brand new bulb should not be used in calculations considering that HPS and MH
fixtures have very low lumen maintenance factors, driving a considerably low mean lumen value for
the lifetime of the luminaire. Therefore when comparing the lumen output of the LED luminaires to
HID luminaires, mean lumen of HID luminaries should be used in comparisons.
An example would be 70W HPS vs 25W OPTICA LED
The effective mean lumens of a 70S HPS is about 2300lm. This can be easily replaced by a 25W OPTICA
LED driving 2875 lumens at 115lm/W.

Although lifetime hours for HPS and MH are stated as 20K hours and 13K hours respectively, according
to information obtained from City of Lights, about 30% of all HPS luminaires require a bulb
replacement within 1 year. This is a tremendous burden on city maintenance budget. LED Lighting
minimum expected lifetime is 50,000 hours, which means 11.7 years of operation time at minimum.
The 10 year warranty already assures 43,570 hours of operation time without any maintenance
expense on the luminaire.
Lighting Industry, for the first time in history, is becoming largely technology based with the adoption
of Solid State Technology, Electronics, Adaptive Control Systems, Networked Control Systems, etc.).
Utilizing the ultimate potential of these new lighting technologies requires the assistance of an expert
like BLUE ARROW. Along with our strong and unique competitive advantage, we understand that large
scale projects requiring strong assurances. Since technology evolves at such a rapid pace, it is
important to always remain open to implementing “best of class” components as they prove their
technical superiority. Many LED luminaire manufactures limit their ability to incorporate “best of class”
components, due to the need to fill and subsequently deplete the distribution channels. They may be
further restricted due to self-developed components and their inability to abandon them in favor of
their “competition”. As a result of this attachment, many cannot shift component selection to take
advantage of these technology advancements. By comparison, BLUE ARROW luminaires always
incorporate best of class components and maintain Just In Time (JIT) inventory strategies, further
ensuring our fixtures always remain current and “ahead of the curve”. This ensures that BLUE ARROW
luminaries will always be in a position to take advantage of the best performing components, further
ensuring exceptional and superior performance from BLUE ARROW luminaires.
Investment Analysis
The economics of an energy efficient lighting initiative are extremely favorable. The typical
reimbursement period is usually under 5 years from the time of installation, depending mostly on local
energy costs. However, especially in low energy cost environments, compelling projects often need
advanced ROI allowance and funding to make them to reality.
Establishing viable funding options is part of our commitment to many projects. Participating in global

LED PRODUCT DESIGN, CONSTRUCTION & SPECIFICATIONS
A key project objective is to provide a solution that will provide many years of high quality, low
maintenance lighting that reduces the grid load and carbon footprint of the region through reduced
electricity consumption. LED lighting is the most efficient light source in terms of converting energy
into light (efficacy) and has the longest useful service life (L70). The product proposed for this project
has the following two key attributes;
• Efficacy of ~115 lumens of delivered light energy per Watt of electrical energy (lm/W)
• L70 ratings >= 100,000 hours of continuous operation based on proven TM-21 calculations
Factors Influencing Efficacy
The primary determinant of system efficacy is the LED chipset. Improvements in phosphor coatings and
GaAs (gallium arsenide) wafer processing have improved best in class performance from <50 lm/W
four years ago to >100 lm/W today. For any given chipset, delivered lumens from the fixture are
determined by the quantity and quality of the various optical interfaces. The Blue Arrow OPTICA
product line benefits from a significant R&D investment in optical component design, resulting in
highly efficient delivery of uniform light to the areas where it is required.
Factors Influencing L70
Heat is the primary factor in determining lumen depreciation and overall system reliability. Removing
heat from the LED package as quickly as possible is achieved by reducing the thermal resistance
between the LED case and the ambient air (ϴC-A) and each material interface in that path increases
thermal resistance and slows the rate of thermal transfer. The total surface area and construction of
the primary heatsink (first interface with LED) is critical to lowering ϴC-A. For passive radiating
heatsinks, aluminum is the best material choice.
The OPTICA line utilizes an aluminum core circuit board for the LED’s as opposed to the FR4 fiberglass
boards used in some value brand fixtures. The circuit board is in turn bonded to a second aluminum
heatsink that acts as the radiating surface(s) to the ambient air. This construction provides the lowest
path of thermal resistance from the LED to the surrounding environment, keeping the LED package
cooler and increasing the L70 rating for the system. Further, the OPTICA model proposed for Tbilisi
has a self-cleaning heat sink design that minimizes the accumulation of dust and debris that would
otherwise negatively impact thermal performance.

Specifications
HOUSING
The OPTICA product family housing is manufactured as a single die cast aluminum piece, including the
light engine, heat sink surface and power chamber, without any extrusion processes. All the different
compartments of the housing include the necessary machined screw holes to hold all the electrical and
optical components. Depending on the international requirements for a particular project, our housing
can be made of Aluminum Alloy ADC12 or A360. ADC12 offers improved strength and resistance to hot
cracking (strength at elevated temperatures), in both cases offering a minimum thickness of 2.5 mm.
The housing does not offer a quick release hinged locking mechanism to provide a tool-less entry to
the power chamber, since a standard long cable preinstalled to the luminaire in order to streamline the
installation process. The power chamber door can open upward and it is completely secured to the
main body of the fixture to prevent accidental opening. The driver housed in this chamber has the
same warranty coverage as the housing and LED module so there is no need for field maintenance.
To provide additional protection against insects, the power lines are inserted into the power chamber
through a rubber gasket that can be tied in order to minimize the intrusion of insects.
OPTICA Product Family is offered with a housing ingress protection rating of IP66. Alternative rating of
IP54 (with drain holes), and Impact Protection rating of IK10 can also be offered.
FINISH
The OPTICA product family can be painted in different colors. The Gray Federal 595B 36173 or Dark
Bronze is the standard color for this product. Custom color finishes are available to match any RAL
CODE. The fixtures are painted following a powder coating process based on TGIC Polyester with a
minimum thickness of 2.5 mm. TGIC consists in a low-molecular-weight, which enables polyester TGIC
formulations to contain 90% or greater resin within the binder system, enhancing the weather-
resistance characteristics of the material. TGIC coatings provide superior coverage of sharp edges and
will also cure at lower temperatures than the polyester urethane. The characteristics of the material
provides resistance finish in accordance with multiples standards for quality and durability, like salt
spray resistance test in according to ASTM B117 for a minimum of 2000 hours test, Impact resistance in
accordance with ASTM D2794, ASTM D3359, among others.

intelligence to your Lighting Infrastructure.
WLCS - LIGHTING CONTROL & MONITORING SYSTEM
This Plug & Play Wireless Lighting Controller (iSLC) with Remote Monitoring,
Dimming, GPS and Sensor Input Capabilities has much to offer, not only in
energy savings initiatives bit also in extensive maintenance savings, multiple
operational structures and even alternative income generating activities.
iSLC-7P is an intelligent wireless lighting controller with exceptional fault
tolerance and a multitude of features. Each module provides intelligent ON/OFF switching, dimming
control, GPS, highly accurate power metering, analog and digital sensor inputs and constant status and
health monitoring of your lighting fixtures. Differentiating Features include:
A PHOTOCELL IN EVERY NODE
All external SLCs (excluding our 480V version) come equipped with built-in photo-sensors which enable
the units to be operational the moment they are connected to the lighting fixture and powered on.
Controllers can thus operate immediately upon installation without dependency on the network. The
photocell also provides redundant backup to time-based scheduling in the event of daylight weather
changes.
A GPS IN EVERY NODE
Controllers also come with an optional built-in GPS chip which enables the nodes to send their exact
location data to the CMS server within seconds of initial power up. GPS capabilities reduce install times
and eliminate mapping issues.
INTEGRATED TILT SENSOR
Provides instant alert for knockdown of the pole
WEB-BASED CONTROL SYSTEM – (User-Friendly Interface)
The system uses intuitive menu options and an interface to Google Maps or site CAD drawings to
quickly identify faults, create groups and schedule fixture operations.
ENERGY METERING
Each SLC is equipped with an energy-monitoring module (up to .5% accuracy) that updates the Central
Management Software (CMS) at programmed intervals. Reports of energy usage are easily generated.
REAL TIME CLOCK
Each SLC has a built-in Real Time clock with a trickle-charged, backup battery. This makes all units
completely self-contained during power failures without relying on the network to get updated times.
It ensures all time based modes are completely operational as soon as power is restored to the lighting
fixture and SLC.

IOS APP (iPad, iPad mini, iPhone)
Enables local control for users (within 5,000 feet of a Controller) to schedule and diagnose outdoor
lights without the need for a Gateway. The iOS app (local control) and web-based (remote control)
applications are not mutually exclusive.
COMMUNICATION INFRASTRUCTURE – Hosted Network
SLCs installed on individual street lights communicate with the Gateway (DCU) over a self-organizing,
wireless mesh network. A standard ZigBee Pro mesh network protocol is used that is based on the IEEE
802.15.4 standard. As a standard open protocol, other devices can be integrated into the same
network. This can extend the street light network to include other devices.
INTEGRATION WITH THIRD-PARTY SYSTEMS
The CMS application is built on an open-architecture and designed to allow integration with web
service calls and/or directly using database stored procedures/triggers from third party systems, such
as Outage Management Systems.

JUNCTION BOX – Assurance for Grid Stability and System Safety
Observations on the streets of Tbilisi and feedback from City of Lights strongly indicate that there is an unstable
voltage environment feeding into the Outdoor Lighting infrastructure. During our visit to City of Lights, we were
informed that transformers/stabilizers have been installed into the Control Boxes to prevent voltage spikes;
however program was discontinued due to high initial cost and insufficient benefit. Also it has been observed
that there are no circuit breakers on lighting poles and some poles are even missing a proper grounding design.
LED Luminaires and Network Controller Systems are expensive propositions that need to be well protected from
such instabilities. Therefore such a control and safety gateway needs to be created either within the Control
Boxes of Outdoor Lighting infrastructure or on the lighting poles themselves.
Considering some of the key safety measures already missing on the poles, we have taken the “Pole Safety”
approach so that we can install a single Junction Box that will assure these safety and stability measures. On top
of these measures, we will also utilize this box as the key installation point which will streamline the installation
process extensively.
Junction Box Contents
• Stainless Steel Enclosure with Clamp for easy mounting
• Surge protector
• Fuse
• 7-Pin receptacle
• Terminal Blocks (in/out) for easy connection between
power line and the luminaire
 Junction Box would be delivered into the field pre-assembled at factory for ease of installation
 Luminaires would be delivered pre-wired with a long cable which would enable the installer to reel the
cable through the pole and connect into the Junction Box easily.
 The only remaining step would be to connect the power line into the Junction box and ground the box.

EQUIPMENT PERFORMANCE & ENERGY EFFICIENCY ASSURANCE PROGRAM
Performance exposure of energy savings improvements would be virtually eliminated
with an A++ rated insurance policy. This Assurance Program effectively eliminates
project performance risk from the lender’s credit assessment for project financing.
With this Assurance Policy attached to an Energy Efficiency Project, borrower will be
GUARANTEED to realize no less than 100% of the projected energy savings.
Energy conservation through more efficient systems and equipment has the potential to save millions of dollars,
reduce emission and strengthen energy independence. There is an enormous opportunity to reduce energy
costs and emissions through various energy conservation measures.
There are many projects that have the goal of financing the project by showing the potential savings. Due to the
complex nature of energy conservation systems and technical uncertainty over the effectiveness of energy
efficiency programs, lenders and investors often see such projects with “potential savings” as an unfavorable
credit risk. This causes a large number of energy projects with viable energy related returns to be unfunded and
never implemented. These opportunities are left behind due to financial considerations like poor credit or
inadequate balance sheets.
Utilizing a patented approach to achieve credit risk reduction, the performance of such energy efficiency
conservation measures is underwritten. This removes any technical uncertainty for lenders allowing them to
concentrate on credit risk. Insuring the performance of projects with a highly rated insurer reduces financial
exposure. This results in improved credit worthiness and lowers interest rates and financing costs.
Energy Efficiency Performance Insurance is customized to the precise requirements of each client and has the
flexibility to tailor terms to address the needs of ESCOs, Banks, Financiers, Investors and Townships. With over
1,200 engineers, inspectors and technical personnel who perform 500,000 inspections in the world, process
