For each application metrics should be used to evaluate LED systems vs. the incumbent technology along the dimensions of lifetime, CRI, CCT, efficiency and cost
Downlight Application Example
In certain cases LED luminaires can meet and exceed CFL luminaire efficacy!

Barriers to adoption of LED technology in General Lighting
•Consistent quality of light»The “b” word for CCT………….»CRI of some of the white light generation techniques (RGB, RGBW,
RW…)
•Standardization»Of terminologies»Of performance metrics»And eventually of light sources/systems
• Initial system costs•Continued rapid pace of change in technology•Emergence of OLEDs, other inorganic LED technologies,
improvements in existing lighting technologies

Conclusion
•LEDs have started transforming the general lighting marketspace
»Initial market penetration has been in specific application segments - signage, architectural lighting, down lighting, cove lighting, streetlighting, undercabinet, shelf lighting, display/freezer cases
»LEDs will evolve to become one of the common general lighting technologies to compete with fluorescent and HID technologies
»LEDs have to overcome “quality of light” performance barriers to deliver on customer expectations
»Several alternative business models will evolve in the mid-term
