Study Reveals How Age Affects Perception of White LED Light

Although LEDs are increasingly used in low-energy lighting and displays, consumers sometimes find their light harsh or unpleasant. Findings from a new study point to the need to take age-related perception differences into account when designing white LED lighting that is more pleasing to the eye. Read more »

CIE Position Statement on Non-Visual Effects of Light - 2nd Edition

On October 3rd, CIE released their new position statement on non-visual effects of light, entitled "Recommending Proper Light at the Proper Time" 2nd edition. As non-visual effects are becoming more attention nowadays, confusion and uncertainties on this topic are still high in the lighting community. Much research has been done but even more research is necessary. CIE has recognized this relevant topic and already initiated an independent workshop of leading scientists in the field of quantifying light for non-visual effects in Manchester in 2013 (CIE TN 003:2015 (CIE 2015)). The CIE issued an international standard, CIE S 026:2018 (2018), that defines a system for metrology of optical radiation for light-induced responses that can be elicited by ipRGCs (ipRGC-influenced light (IIL) responses).

BTS256-EF Measures New Flicker Metrics for Compliance with Ecodesign Directive

The European Commission´s proposed regulation of lighting under the Ecodesign Directive will establish mandatory product performance and quality requirements on all lighting products. This new EU directive will include strict requirements for flicker and stroboscopic effect, collectively referred to as temporal light artefacts (TLA). Simple measures such as flicker index and modulation depth will not be adequate as they do not distinguish the possible TLA effects and do not account for the effect of frequency-dependent sensitivity or the wave shape of light output. The BTS256-EF spectral light and flicker meter measures the specific metrics required by the regulation, PstLM and SVM. Read more »
