What We’ll Cover Today
• Why NGL?
• How NGL works
• What you can learn from what we have done
• What we have seen in the last 5 years
• What the entries and winners have shown us
• How NGL can help in the future
Why NGL?
What Designers/Specifiers need to know.
• Does it perform as expected for the intended location
or function?
• Is it bright enough?
• Is the color right?
• How easy or difficult was installation?
• Is it serviceable?
• How will it perform over time?
What Makes NGL Different?
• Inclusive rather than exclusive
• Performance evaluation with extensive
documentation
– More time and resources than most
designers can afford
• Judged in characteristic applications
and “hands on”
• Diverse, professional judging panel
How NGL Works
Judging is the Key
• Approach
• Criteria
• Installations
• Evaluations
• Selecting Winners
Judging Approach
• Organized by application
• Product Evaluation
• Installed and lighted
• Table top (2nd fixture)
• Documentation
• Process
• Independent judgment
• Preliminary scoring
• Discussion and decision
• Post judging analysis &
verification
Judging Criteria
In-person evaluation:
• Color
• Illuminance
• Light distribution
• Glare control
• Serviceability
• Value
• Aesthetic appearance
• Bonus (flexibility, innovation,
dimming)
Documentation analysis:
• Luminaire Efficacy
• Lumen maintenance

Scoring
• Each category is evaluated in terms of the application
for which the product is intended.
– 0 = Not acceptable
– 1 = Acceptable
– 2 = Good
– 3 = Very good
– 4 = Outstanding
Products scoring a „0‟ in categories 1-7 are suspect for “specifiability”.
Pre-scored Criteria –
Efficacy & Lumen Maintenance
Efficacy Scoring Rationale
• Below requirement: 0
• At requirement to +10%: 1
• +11% to +40%: 2
• +41% to +75% 3
• Over +75% 4
Lumen Maintenance Scoring Rationale
• Meets minimum 70% LM at 50,000 hours 0
• 70% < LM < 80% 1
• 80% < LM < 88% 2
• 85% < LM < 90% 3
• LM > 95% 4
Selecting Winners
• Recognized means „suitable for specification‟
• Best in Class must stand out overall and in category
– Relatively few products meet this dual standard
Learn From What We Have Done
• Install samples in intended applications
• Take things apart
• Review documentation
– Get the facts
– Check the facts
– Know what you‟re looking at and why

Indoor Judging Setup
Seeing is Believing
Take Things Apart
• How much time to install?
• What can be replaced?
• Can it be serviced?
Outdoor Installations –
Time is the Key
Controls – What a Mess!
Documentation –
What You Need to Know
• Will it perform as claimed?
• Will it perform as expected for its intended us?
• Will it perform as claimed/expected over time?
• Will it dim as claimed/expected?
• Will contractors have issues with installation?
• Will it have color consistency issues across products and
over time?
• At end-of-life, will it be disposed of in a responsible
manner?
• How does its performance compare with other products
What NGL Requires
General
• Luminaire specification sheet
• Product photos/marketing materials
LED Lighting Facts documentation
• LM-79 test report (including sphere data)
• LM-80 test report on LED package/module/array
• LED package/module/array specification sheet
• ISTMT on submitted model
• ENERGY STAR TM-21 Calculation
Other
• Installation/serviceability statement
• Driver specification sheet/dimming interface spec sheet
• Product warranty/end-of-life statement
Understanding Lumen
Maintenance Projections
• Lumen maintenance % is not a lifetime metric
• It is % light output after a specified time vs. initial output
• Measures source only - in thermal environment of
luminaire
• In contrast, lifetime metric includes all system
components (electronics, optics, thermal management,
housing etc.)
• No industry standard for lifetime is yet available

What NGL Has Shown Us
Speaking Up Does Make a Difference
• Documentation – what we need and why
• Serviceability – it will need to be serviced EVENTUALLY
• End of Life Policies – they do matter
• Color matching across products – certain applications
demand it
• Color shift – does anyone know?
• GLARE GLARE GLARE
Interesting Approaches Are Possible
Glare vs. Efficacy –
the Battle Continues
• Efficacies continue to increase
• Most frequent negative judging comment is typically
related to glare
Seeing What’s
on the Horizon
• 2012 – Troffers - we‟ve arrived! (8 recognized products)
• 2013 - Downlights - ho-hum (0 recognized)
• 2013 - Color tuning products, on the horizon

Session 7 - What NGL Tells Us About State of the Arts in LED Luminaires

  • 1. Next Generation Luminaires What NGL Tells Us About the State of the Art in LED Luminaires March 19, 2014 Craig Bernecker, PhD, FIESNA, LC; The Lighting Education Institute Ruth Taylor, IES; Pacific Northwest National Laboratory Dan Blitzer, LC; The Practical Lighting Workshop
  • 2. Competition Partners International Association of Lighting Designers IALD Partnerships to link energy efficiency & lighting quality
  • 3. What We’ll Cover Today • Why NGL? • How NGL works • What you can learn from what we have done • What we have seen in the last 5 years • What the entries and winners have shown us • How NGL can help in the future
  • 4. Why NGL? What Designers/Specifiers need to know. • Does it perform as expected for the intended location or function? • Is it bright enough? • Is the color right? • How easy or difficult was installation? • Is it serviceable? • How will it perform over time?
  • 5. What Makes NGL Different? • Inclusive rather than exclusive • Performance evaluation with extensive documentation – More time and resources than most designers can afford • Judged in characteristic applications and “hands on” • Diverse, professional judging panel
  • 7. Judging is the Key • Approach • Criteria • Installations • Evaluations • Selecting Winners
  • 8. Judging Approach • Organized by application • Product Evaluation • Installed and lighted • Table top (2nd fixture) • Documentation • Process • Independent judgment • Preliminary scoring • Discussion and decision • Post judging analysis & verification
  • 9. Judging Criteria In-person evaluation: • Color • Illuminance • Light distribution • Glare control • Serviceability • Value • Aesthetic appearance • Bonus (flexibility, innovation, dimming) Documentation analysis: • Luminaire Efficacy • Lumen maintenance

  • 11. Scoring • Each category is evaluated in terms of the application for which the product is intended. – 0 = Not acceptable – 1 = Acceptable – 2 = Good – 3 = Very good – 4 = Outstanding Products scoring a „0‟ in categories 1-7 are suspect for “specifiability”.
  • 12. Pre-scored Criteria – Efficacy & Lumen Maintenance Efficacy Scoring Rationale • Below requirement: 0 • At requirement to +10%: 1 • +11% to +40%: 2 • +41% to +75% 3 • Over +75% 4 Lumen Maintenance Scoring Rationale • Meets minimum 70% LM at 50,000 hours 0 • 70% < LM < 80% 1 • 80% < LM < 88% 2 • 85% < LM < 90% 3 • LM > 95% 4
  • 13. Selecting Winners • Recognized means „suitable for specification‟ • Best in Class must stand out overall and in category – Relatively few products meet this dual standard
  • 14. Learn From What We Have Done
  • 15. • Install samples in intended applications • Take things apart • Review documentation – Get the facts – Check the facts – Know what you‟re looking at and why
  • 19. Take Things Apart • How much time to install? • What can be replaced? • Can it be serviced?
  • 21. Controls – What a Mess!
  • 22. Documentation – What You Need to Know • Will it perform as claimed? • Will it perform as expected for its intended us? • Will it perform as claimed/expected over time? • Will it dim as claimed/expected? • Will contractors have issues with installation? • Will it have color consistency issues across products and over time? • At end-of-life, will it be disposed of in a responsible manner? • How does its performance compare with other products
  • 23. What NGL Requires General • Luminaire specification sheet • Product photos/marketing materials LED Lighting Facts documentation • LM-79 test report (including sphere data) • LM-80 test report on LED package/module/array • LED package/module/array specification sheet • ISTMT on submitted model • ENERGY STAR TM-21 Calculation Other • Installation/serviceability statement • Driver specification sheet/dimming interface spec sheet • Product warranty/end-of-life statement
  • 24. Understanding Lumen Maintenance Projections • Lumen maintenance % is not a lifetime metric • It is % light output after a specified time vs. initial output • Measures source only - in thermal environment of luminaire • In contrast, lifetime metric includes all system components (electronics, optics, thermal management, housing etc.) • No industry standard for lifetime is yet available
  • 25. SSL Testing Methods Luminaire Electronics LED packages Thermal Management LM-82 LM-79 AC LEDs WG TM-28 TM-26 Waveform WG Remote Phosphor WG LED Reliability WG LM-84 LM-85 LM-80 TM-21 Optics/Phosphors Color Stability WG

  • 28. LM-79 Scope • Applies to LED-based products incorporating control electronics and heat sinks: – Products requiring only line voltage or DC power supply – Includes complete LED luminaires and – Integrated LED sources (LED chips with heat sinks) • Does not cover – LED products requiring external operating circuits or heat sinks (bare LED chips, pkgs, and modules) – Fixtures designed for LED products but sold without a light source
  • 29. Integrating Sphere Photometric Report • Total Luminous Flux • Spectral Power Distribution • Chromaticity Coordinates • CCT • CRI
  • 30. Goniophotometry • Luminous Intensity Distribution • Total Luminous Flux • Zonal Lumen Sums • IES Format File (LM-63)
  • 34. TM-21 Calculations Drive current of chip for luminaire ISTMT must be less than drive current of chip for LM80 test.
  • 35. TM-21 Calculations Enter highest measured LED temp from ISTMT. Enter projected hours and read resulting lumen maintenance.
  • 36. TM-21 Calculations Enter LM-80 data from chip manufacturer
  • 37. 2014 Standards Workshop Update Held March 17-18, 2014 – Destin, FL Working groups formed to create: • Educational guide on using SSL standards and testing reports • Electronic file format for testing data • Testing method for color tuning products
