IEA Annex releases draft SSL performance tiers
A solid-state lighting program run by the International Energy Agency (IEA) has released draft performance tiers for four different SSL product types.
The Annex will be collecting suggestions and comments from all stakeholders from November 1, 2011 until February 1, 2012. It will then revise the performance tier levels, definitions and criteria based on feedback received. More details on submitting comments on the SSL Performance Tiers can be founding the Annex’s cover letter.
The Annex was established in 2009 to help its member countries to implement quality-assurance programs for SSL lighting. Its aim is to build consensus between member governments and to provide guidance to interested stakeholders.
This international collaboration brings together the governments of Australia, Denmark, France, Japan, Sweden, The Netherlands, the UK and the USA. A Chinese laboratory (NLTC) is also involved in the process of establishing the performance tiers.
Marc Fontoynont, the Operating Agent for the IEA-4E SSL Annex and a professor at the Danish Building Research Institute, Aalborg University, discussed the Annex at the recent Strategies in Light Europe conference.
The four categories of SSL products are:
- SSL Omnidirectional replacement lamps
- SSL Directional replacement lamps
- SSL Downlight fixtures
- Linear LED fluorescent replacement lamps
- Tier 0: Minimum acceptable performance for off-grid applications
- Tier 1: Minimum Acceptable Performance for grid-connected applications
- Tier 2: Performance required by established quality programs
- Tier 3: Current highest commercially-available performance
The draft performance tiers have been developed with the assistance of twenty technical experts from nine countries including China, and represent “early-stage proposals.” They do not reflect an agreed position by member governments at this stage, says the IEA, but are issued “to provide a basis for meaningful engagement with industry and other stakeholders.”
