Confidence
• Large scale trials undertaken (Bedford 2,000 pieces)
• Other large scale installations monitored (Lancashire 7,000 pieces)
• Key supply chain partner – open access to performance data
• Defect rate comparisons and early failure data reviews
• Access to R and D Data
Confidence – is it the best solution?
• Evaluation of alternatives :
– Total cost of ownership
– Carbon impact
– Reliability / failure rates
– Sustainability

Central Management & Control System
• 33 transmitter stations
• Long range, high capacity, low
power
• Combined monitoring and control
nodes.
• Group / individual switching and
dimming control
• Flexibility control - 0-10V & DALI
compatible
• Energy harvesting capacity
• Provides active control for
individual lighting columns
• Future proofs the lighting network
• Negates outage detection cycle
• Facilitates variable lighting levels,
trimming, energy metering
• Constant light output (MF
harvesting)

Lighting Case Study
Lighting Case Study
(1) Original Lighting Situation
• Originally 7 Lighting Points
• 7 x 80W MBFU luminaires
• Not to EN standards
• Total Power Consumed
= 658 Watts (e.g. 7 x 94W)
13
(2) Pre-PFI Proposed Design
• S3 / S4 standard
• Maintained lighting levels
• Schreder Sapphire 70W
SON
• 11 lighting points
(4 additional).
• 11 x 79W = 869W
• 32% power increase
(3) Amey PFI Design
• Compliant S4 / S5
• 7 lighting points
• Connection costs minimised
– value engineering
• Total Power = 270W
• 658W – 270W = 388W
saved
• 59% saving vs. original
scheme
14
Energy Comparison
Type Lighting Points Total
Mercury Installation 7 658 W
Sodium Installation 11 869 W
LED Solution 7 270 W
LED Saving = 59% against original MBFU solution.
LED Saving = 69% against typical SON.
* Without Dimming
Outcomes
• Compliant to standards
• Better quality lighting
• Reduced energy and carbon emissions
• Reduced maintenance – outages / detection /
vehicle journeys / replacement lamps and
components
• Reduced total cost of ownership
