The DiiA will now do its business as the DALI Alliance, and the most recent action of the standards body is certification services for D4i sensors that can be added to SSL luminaires...
As in the food and cosmetics industries, the definition of the term ‘natural’ is debatable and nebulous. When it comes to discerning this quality of light, what is the benchmark...
Expressed as a percentage, the Average Spectral Difference quantifies the output of LED sources relative to reference illuminants, presumably offering a measure of naturalness...
PNNL scientists investigate the potential of a new NEMA ANSI standard to address performance variations that may be found across 0-10V dimming controls for outdoor LED luminaires...
Be ready to execute on essential intellectual property protections while also maintaining a conservative approach to related costs during tricky financial times, advises consultant...
![FIG. 1. The timeline of light sources relied upon by humans has evolved from one focused on the source of illumination for visual acuity alone to one that applies advanced research to evoke or inhibit certain responses from the non-visual system. The research will deliver new information to the solid-state lighting (SSL) industry for producing metrics that enable standards and best practices development for products and lighting designs.

![Nocturnal melatonin suppression to narrowband light sources from two independent studies [8,9] shows a peak sensitivity at approximately 460 nm. Also shown are the photopic luminous efficiency function peaking at 555 nm and the action spectrum for melanopsin peaking at approximately 480 nm.
