What happens when we stop thinking about lighting only in terms of lumens, illuminance, CCT and CRI?

In this interview, Kei Haraguchi explains the thinking behind Dynasolis\u2014a simple system using two LED sources that allows both CCT and melanopic ratio to be tuned independently.

The bigger idea is even more important: as LED efficiency approaches its theoretical limits, the next opportunity for innovation may be spectrum design.

Instead of optimizing lighting only for energy efficiency, the industry can begin asking:
\u25aa\ufe0f How can light better support human health and well-being?
\u25aa\ufe0f How should we measure the biological impact of light?
\u25aa\ufe0f What new metrics should complement traditional lighting measurements?
\u25aa\ufe0f How can manufacturers, designers, governments, business and academia work together to redefine the value of light?

Kei also highlights the need to look beyond traditional metrics and consider measures such as melanopic ratio and equivalent melanopic lux when evaluating lighting.

This is an important conversation as we move toward a future where lighting is not only energy-efficient, but also human-centered and health-supportive.<\/p>\n\n\n\n
