How to organize a modern photometric laboratory Part 1 – selecting a goniometer system

Many manufacturers of lighting products use external measurement laboratories to verify compliance with standards and assess performance. Some manufacturers or importers rely solely on their suppliers' datasheets and try to avoid having to carry out measurements on their own. This situation is quite common not only among small start-ups but also larger lighting companies in [...]

Modern Lighting Audits. Technology supporting designers and contractors to verify lighting conditions

Available lighting design software tools support architects, engineers, and designers with the calculation and simulation of luminance levels and even correlated color temperature (CCT), but little is available for on-site verification tools. Nevertheless, verification can insure conformance for specific application requirements such as detailed task-work, food inspection, color critical viewing, warehouse isles, safety exit signs, [...]

Understand the causes, consequences, and measurement of light flicker

As modern energy-efficient lighting technologies, including LED-based solid-state lighting (SSL), proliferate in our environment, awareness of their impact on biology and even technology evolves as well. LED lighting’s rapid development and assimilation, often without clear standards, may result in lighting flicker with adverse effects. Many organizations, including international standards bodies and regulatory agencies, and industry [...]
