of any material of construction or any method or manner ofhandling, using, distributing, or dealing in any material or product.___________________________________________Questions related to specific materials, methods, and services will be addressed at the conclusion of this presentation.
LearningObjectives
At the end of the this course, participants will be able to:
1. Understand the new Next Generation Luminaire Systems competition.
2. Assess preliminary specifications for connected lighting systems.
3. Assess evaluation criteria for connected lighting systems.
4. Engage with the upcoming phases of the competition.
Is LED Lighting Old News?
Shifting focus from luminaires to connected lighting
NGL – Past and Present
Building off what we have learned
Connected Lighting Pilot 2016
2017 Big, big changes
What we are trying to learn
How you can be involved
Partnerships link energy efficiency & lighting quality
Mission: support the effective application of solid-state lighting in the general lighting market by focusing on high-quality, high-performance SSL products that achieve significant energy savings and deliver lighting quality
Hands-onvisual
deliberativedocumented
2008: Focus on LED luminaires of different types.
2012: Split into separate Indoor and Outdoor Competitions
2015: Focus on controllability and serviceability
2016: Focus on specific applications and connected systems
From Next Generation Luminaires to Next Generation Lighting Systems.
2017: Exclusively Indoor Connected Lighting Systems Build on 2016 experience
Separate into levels of system complexity and performance
Permanent installations
Ongoing evaluations
Emphasis on specific applications:
High-lumen capabilities in general area luminaires
Controllability
Pedestrian-scale outdoor
Sensor-integrated garage
25 indoor and outdoor luminaires recognized
Nearly 80% of entries exceeded L85 at 50,000 hours
Over 30% of entries had greater than 90 CRI
Dimming was a critical criteria (rather than bonus)

Installation/configuration
External controller with networked luminaires
Self-contained network (all logic on board)
Benefits: Robust control functionality, typically can interface with BMS Many options for luminaire styles Well suited for new construction and complex projects
Limitations: Dual points of responsibility More complicated installation More complicated start up and commissioning Cost for smaller projects
Manufacturer supplies control system, luminaire by others
Benefits: Integrated solution, single point of responsibility Simple installation, start up, and commissioning Well suited for retrofits and smaller projects
Limitations: Limited control functionality Limited options for luminaire styles
Integrated fixture/control “out of the box”
Three of four entries judged “Notable” – each had strengths and limitations, limiting useful conclusions.
How do you know how system capability matches to project needs (mostly by experience today)?
How do you know that you have correctly configured a system – is professional commissioning necessary?
In practice, if a system fails to meet expectations, is it capability, configuration, or defect?
More robust evaluation setting (sensors)
Better configuration process
