IC 2023 Nucleus Laboratory Comparison Report, Part 2: TLM Generator Artefact
This Nucleus Laboratory Comparison report – Part 2 is part of the 2023 Interlaboratory Comparison (IC 2023). IC 2023 is investigating the degree of agreement in the measurements of temporal light modulation (TLM) quantities, in particular, short-term flicker indicator (PstLM), and stroboscopic effect visibility measure (SVM).
Results of IEA 4E SSL Annex Interlaboratory Comparison on Temporal Light Modulation Measurement
Abstract: The International Energy Agency (IEA) 4E SSL Annex has conducted an Interlaboratory Comparison (IC 2023) of the measurement of temporal light modulation (TLM) of solid-state lighting (SSL) products. Designed to meet proficiency test requirements, IC 2023 compared measured TLM quantities including short-term flicker indicator (PstLM) and stroboscopic effect visibility measure (SVM, MVS), as well […]
Interlaboratory Comparison for Temporal Light Modulation Measurement
The 4E SSLC Platform has conducted an Interlaboratory Comparison (IC 2023) for the measurement of temporal light modulation (TLM) of solid-state lighting (SSL) products. Designed to meet proficiency testing requirements, IC 2023 compared measured TLM quantities of short-term flicker indicator (PstLM) and stroboscopic effect visibility measure (SVM, MVS), as well as three other TLM quantities, of four comparison LED lamp artefacts.
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 […]
