Addressing Committee Issues
Flicker: Tracking standards under development
 ENERGY STAR - Specification under development (2014)
 NEMA LSD 49-2010, ”Solid state lighting for incandescent replacement—
best practices for dimming” http://www.nema.org/stds/lsd49.cfm
 IEEE PAR1789 http://grouper.ieee.org/groups/1789/
Dimmability compatibility: program design options
 Product specifications – which elements predict quality (efficacy, CRI PF):
Subcommittee participating with West Coast Lighting Group. Will be
comparing notes with CA utilities’ approach to quality.
 BPA regional promotion will test in-store materials to assist consumer.
 BPA regional lighting promotion will request product return information from
participating retailer (number and reason).

Committee Recommendation for 2013
 Present Energy Star LED bulbs to Regional
Technical Forum:
•
Expect most measures to pass TRC based on
preliminary analysis
•
Energy Star spec and above allows programs to
focus promotions on high quality products
•
Provides opportunity to test return rate of this
product class

Proposed Sunset Date
 Return to the RTF in March 2014 with
product sales data:
• Effective Date of Energy Star Integral LED
Lamp Update
−Currently on draft 3
−Expected to go into effect early 2014
• Rapid changes to technology, costs,
standards that effect measure savings by
more than 10%
