As more and more organizations consider lighting upgrades for outdoor lighting, they are met with a unique opportunity to also bring intelligence to their lighting systems by bundling controls along with the LED upgrade. But controls are unknown territory for many decision makers. And with LED lifespans ranging upwards of 20 years, they want their construction or design professional to perform a comprehensive technology assessment before selecting a technology they will be using for the next generation. Today, both wired and wireless options are available in the marketplace, how does the professional make sure which technology is the best for the project? In this session, Rita Renner will explore the benefits of each technology as well as the challenges, then look at ideal applications for each. She will also examine actual case studies where only one control technology was used, as well as examples where both technologies were used together, to illustrate how real project teams made assessments and implemented the best technology platform for their situation.

4.  As more and more organizations consider lighting upgrades for outdoor lighting, they are met with a
unique opportunity to also bring intelligence to their lighting systems by bundling controls along with
the LED upgrade.
 But controls are unknown territory for many decision makers. And with LED lifespans ranging upwards
of 20 years, they want their construction or design professional to perform a comprehensive
technology assessment before selecting a technology they will be using for the next generation.
Today, both wired and wireless options are available in the marketplace, how does the professional
make sure which technology is the best for the project?
 In this session, Rita Renner will explore the benefits of each technology as well as the challenges,
then look at ideal applications for each. She will also examine actual case studies where only one
control technology was used, as well as examples where both technologies were used together, to
illustrate how real project teams made assessments and implemented the best technology platform for
their situation.

5.  What are benefits of intelligent outdoor lighting control solutions?
 Understanding wired and wireless control technologies
 Understanding the pros and cons of each control technology and which
applications are ideal for each technology
 Combining wired and wireless control technologies effectively
 Looking at real world projects using wired, wireless and combined solutions

 More responsive lighting leads to increased revenues and/or
productivity
 depending on application can reduce the payback period by
25%-80% over and above LED replacement

8.  Fixed time of day dimming & astronomical
clock
 Potential Savings up to 15%
 Dynamic/Direction of Travel Lighting
 Event based dimming strategies
 Potential Savings up to 25%

9.  Virtual Power Output
 Create any power lamp desired
 Potential Savings up to 10%
 Lumen Maintenance
 Compensate for light loss over time
 Potential Savings up to 10%

10.  Extending Useful Life
 Improving Light Level
 Increasing Safety
 Reducing Liability
 Enhancing Exception Handling
 Reducing Night Patrols

11.  Standalone control solutions
 Pole specific unconnected devices provide basic automatic ON/OFF according to onboard
scheduling or astronomical control
 No intelligence
 Networked control technology platforms:
 Introduce intelligence both at the control device for distributed intelligent control at the pole
 Centralized intelligent control for scalability, data analysis, and smart applications
 Two basic control technology platforms:
 Wired power line control networks
 Wireless RF control networks
 Hybrid systems that combine “wired” and wireless

12. – No new wiring; uses existing AC power wiring
– Adds modulated communication signal to existing AC power wiring
for control communications

13. – Environments where wireless technology is
challenging
– Subway tunnels
– Bridges
– Historic districts or other locations where decorative
fixtures are used

14.  Uses RF communication protocol to send control signals to individual fixtures,
transmit usage data back to central management system
