White: 2700K (warm)
Color: 90+ CRI
Efficacy: 60+ Im/W
While maintaining high power efficiency
Achieves 50% higher efficiency than next closest product
Dramatic energy savings for consumers

Environmental Net Benefits
LED w/ Quantum LightTM increased environmental benefits
Reduced cost of light to our customers
Reduced electricity consumption (by 80%!) to their customers
~25 mg reduction per bulb due to Hg-free product
Reduced energy consumption leads to lower CO2 emissions
Global Regulation of Nanotechnology – May 7, 20109
Reduced energy consumption leads to lower CO2 emissions
Less manufacturing waste due to longer life
Largest benefit is that consumers will WANT this product
Market uptake is ultimate driver of environmental benefit
Legislation is a poor substitute for a better product

Health and Safety Considerations
Understanding of the health and safety impact of quantum dot materials is in the early stages:
Limited number of literature reports on biological QDs and their cytotoxicity and pharmacokinetics
Very limited literature on our types of QD materials
QD Vision is playing a leading role in advancing this
Global Regulation of Nanotechnology – May 7, 201011
QD Vision is playing a leading role in advancing this understanding, which requires:
Open & facile collaborations (next chart)
Open communication between industry, researchers, and government (e.g. today)
Appropriate levels of funding
Confidential information protection
Responsible Development
US NIOSH – Chuck Geraci
Established QD R&D occupational health and safety best practices
Presented in US and Taiwan
University of Massachusetts – Prof. Michael Ellenbecker
Product safety feedback studies
State of the art nanoparticle detection and analysis
Conservation Law Fund Ventures – Jo Anne Shatkin, Ph.D.
QD Vision has proactively established EH&S community collaborations

Life cycle risk assessment – “the most comprehensive LCRA ever performed for a nano-material” presented at Society for Risk Analysis Annual Meeting, 12/7/09
Brown University – Profs. Robert Hurt and Agnes Kane
EPA STAR Grant, end-of-life fate studies
Below detectable range for EPA Method 1311/6010B/3010A
OECD Nano- Working Group Participation
Goal is to launch product with environmental benefit, by bringing
EH&S information into the development process early.
Regulatory Compliance
European Union developed RoHS (“Regulation on Hazardous Substances”)
RoHS compliance for devices containing Cd-based QD materials will need to be determined on a case-by-case basis
US EPA TSCA (“Toxic Substances Control Act”)
QDV first to file for TSCA approval of a quantum dot
Global Regulation of Nanotechnology – May 7, 201013
QD Vision’s first product material is TSCA ‘approved’, uniquely for QDs worldwide
LoREx exemption applied for and received
P2 Recognition (Pollution Preventing) material
Working directly with those drafting policy around QDs within TSCA
Although Cd-based materials may be acceptable in many applications, QD Vision is committing significant resources to the development of Cd-free compositions
Appropriate strategy given global regulatory trends
(Small) Business Perspective on Global Regulatory Picture
Goal should be keeping public safe while providing
hospitable and predictable business environment to
develop and manufacture novel nanomaterials products
(jobs, jobs, jobs…)
Consistent, well-defined, early regulation may not be a bad
Good regulation is better than no regulation!
Global Regulation of Nanotechnology – May 7, 201014
Consistent, well-defined, early regulation may not be a bad
thing, but we need the scientific basis to get it right
Public-Private-Partnership (such as Tuesday’s US EPA &
National Academy of Science Research Strategies Meeting)
needed to establish the basis, quickly, to regulate
intelligently
