LED Product Lifetime Testing Report

A new report by the IEA 4E Solid State Lighting Annex provides a look across the body of literature on lifetime definitions for LEDs and LED products. The reports looks at failure mechanisms, accelerated life tests and test methods for estimating lifetime, and provides some recommendations. There is currently no agreement as to which test […]
Interlaboratory Comparison for Goniophotometers (IC 2017)

The final report from the IEA 4E Solid State Lighting Annex’s 2017 Interlaboratory comparison (IC 2017). This comparison had 36 participating laboratories from 19 countries with a total of 42 goniophotometric instruments, the largest interlaboratory comparison of such equipment ever undertaken. This comparison investigated the level of agreement in measurements of SSL products by various […]
Controls Validation Method for Variable Speed Air Conditioners and Heat Pumps

This controls validation method aims to provide a uniform method of test which will validate native control operation and performance criteria for residential air conditioners and heat pumps with variable speed compressors. This method is intended to be used as a confirmation against regulatory tests in which modulating component(s) are overridden.
AC/HP Test Methods 2.0: Phase 2 Findings Summary

This research aims to develop an internationally applicable load-based test method for variable capacity ACs and HPs and has 4 Phases. This report discusses the findings of Phase 2 (Investigative Testing of Key Issues), as well as the research team’s recommendations for Phase 3 work.
Literature Summary of Lifetime Testing of Light Emitting Diodes and LED Products

A summary of the literature on lifetime definitions for LEDs and LED products, including a look at failure mechanisms, accelerated life tests and test methods for estimating lifetime, and provides some recommendations. There is currently no agreement as to which test method can best estimate the lifetime of LED lighting products and the report thus addresses a key issue for regulators and industry interested in deployment of LED technologies
