COMMERCIALLY AVAILABLE LED PRODUCT EVALUATION AND REPORTING PROGRAM
Recent Findings from CALiPER Testing

CALiPER at a Glance
Why testing products is valuable: Capture market trends and gauge performance levels Identify important areas for improvement Manufacturer accountability Inspire consumer confidence
Scope of products: SSL General illumination White light Market available
www.ssl.energy.gov 4 | Solid-State Lighting Program
CALiPER Process
Product Selection & Purchasing
Independent LM-79-08 Testing
Data Analysis
Report Publication
www.ssl.energy.gov 5 | Solid-State Lighting Program
Step 1: Selection & Purchasing
I. Industry observations Conventions, trade shows, and conferences Trade publications, popular media Manufacturer marketing materials
II. LED Lighting Facts quality assurance concerns Do reported values reflect commercially available products?
III. CALiPER guidance committee
Manufacturers can’t request tests or submit products!
www.ssl.energy.gov 6 | Solid-State Lighting Program
Step 1: Selection & Purchasing
Challenges in the early stages: Setting criteria—capture the market? ‘Vapor fixtures’—we just can’t get them Very long lead times We must be very careful that we receive what we ordered Products sometimes arrive damaged or broken
www.ssl.energy.gov 7 | Solid-State Lighting Program
Step 2: SSL Luminaire Testing
Independent testing laboratories
Uses absolute photometry rather than relative photometry (IES LM-79-08) Must measure luminaire as a
complete system
Benchmark products for each application are also tested to LM-79
Integrating sphere and goniophotometer testing

www.ssl.energy.gov 8 | Solid-State Lighting Program
Step 3: Data Analysis
Performance compared to conventional technologies
Performance relative to manufacturer data
Evaluation of equivalency claims
Comparison to LED Lighting Facts
Comparison to ENERGY STAR® (or other) criteria
www.ssl.energy.gov 9 | Solid-State Lighting Program
Step 3: Data Analysis
Key questions to answer: Does the product perform as claimed?
Marketing literature (equivalency and performance claims) Specification sheets (at the time of the order) Product packaging
Does the product perform as expected? What are you replacing? What are you trying to accomplish? How does the SSL product compare to conventional alternatives?

CALiPER Test Results
[All Product Types]
www.ssl.energy.gov 18 | Solid-State Lighting Program
High Level Observations
Overall improvements in light output, efficacy, light distribution, power factor, color quality
Manufacturer claims are improving (LED Lighting Facts label helps) but equivalency claims are still a problem
Suitability often depends on application Comparable products are now found in many lighting applications Poor performing products are also found
Careful comparisons based on accurate performance data is an absolute necessity
Be cognizant of “secondary” quality issues: glare, flicker, color tolerances, physical formats, reliability…

Comparison to First Study
Lumen output, efficacy, and color rendering all improved when evaluated on a cost per lamp basis. Increased prevalence of product labels
Significant increase in number of lamps with ENERGY STAR qualification (29% vs. 6%).
Significant increase in number of lamps listed by LED Lighting Facts (61% vs. 15%).
Better at meeting manufacturer data In RRL1, 56% of products met output claims, whereas in RRL2, 68%
met output claims (92% met or were above). In RRL1, 79% of products met color quality claims, whereas in RRL2
92% met color claims (both CRI and CCT). More for the money
55% reduction in cost per kilolumen ($63 versus $139) in just 15 months
38% reduction in cost/lumen/watt ($0.49 versus $0.79) in just 15 months
