THE TYPICAL OPTIONS FOR SUSTAINABLE BEHAVIORThree Steps:
• Reduce• Reuse• Recycle
• Are there other opportunities at end of life?
• What happens at premature end of life ?• Is just fulfilling the warranty
“environmentally sufficient”?• What happens to premature
failures after replacement?

- We launched LED business in 2000!- With even a 10 year life of LEDs, those early units are now failing

LOOKING AT EARLY DATA OF FAILURES FROM STREET LIGHTING
DR. CHIPS CONSULTING LLC Innovate & illuminate ©
5 years into rollout data from Kinzey, PNNL May 2015• 5+ Million street lights installed• Average number of failures is
1% based on limited responses• Traffic signal report
suggests higher failure rates (MSSLC Report)
• Anecdotal reporting of failures is significantly higher (where low cost – low quality units were deployed)
• 1% = 50,000 units

IN STREET LIGHTING
DR. CHIPS CONSULTING LLC Innovate & illuminate ©
• The failure modes can be a range of behaviours• Light is out• Light is blinking• Optics and glare issues are serious• Controls do not work• Light output or distribution is below specifications
• LED component and mechanical parts usually still usable• Working parts may have the highest level of embodied
energy!• Traditional lights which are still in use have significant
embodied energy

RECENT WORK ON STREET LIGHT PERFORMANCE
DR. CHIPS CONSULTING LLC Innovate & illuminate ©
• Study under extreme conditions may be an accelerated test of system! • (A. Wilkerson, J. McCullough, PNNL
Sept 2015)• LED outdoor lights installed in
area with average high temp of 90 C (Yuma)
Preliminary results:• Lumen depreciation of nearly
30% in approximately 1 year (in some zones)
• Early failure may be due to unique lamp characteristics
• Further studies needed and are ongoing

3 CATEGORIES OF LIGHTING PRODUCTS TO “UPCYCLE”
DR. CHIPS CONSULTING LLC Innovate & illuminate ©
1. Millions of traditional lighting fixtures installed – with substantial embodied energy vested in them
2. Millions of SSL units installed over the last decade, some with early failures
3. Millions of SSL units installed over the last decade, still working but already obsolete or not state of the art
Old lighting mindset: install -> burnout -> replaceNew lighting attitude: install -> upgrade -> reuse?

REMANUFACTURING IS NOW IMPLEMENTED IN HOME GOODS AND APPLIANCE INDUSTRY
DR. CHIPS CONSULTING LLC Innovate & illuminate ©
Leading appliance remanufacturer: • Saved several million appliances
from landfill over 4-5 years• Also repaired > 35K discontinued
appliances in one year• How can lessons learned be applied
to SSL?• What are key drivers for an industry
wide solution?• How to apply ideas of circular
economy for an economically viable solution?
• What role can public policy play?

HOW TO APPLY LESSONS FROM APPLIANCES TO SSL?• Let us be proactive• Apply to high value fixtures and
applications first• Potential candidates: Outdoor and
area lighting, high bay, other specialty fixtures
• Remanufacture extends product life by incorporating UPGRADE
• Government buildings, municipalities and academic institutions are ideal initial candidates due to public interest philosophy
• It is time for a pilot project to develop ideas and ecosystem

STAKEHOLDERS WANTED!• Stakeholder categories?
• End-users, public units• Collection services• Recyclers• OEMs• Resellers and installers

Remanufacturers
Ecosystem: develop a pilot program to explore remanufacturing to implement a circular economy for SSL
