01 — Why it qualifies as HCL

Circadian performance, stated as measurable numbers

Tunable white is a colour feature. Human Centric Lighting is a measurement obligation. Below are the quantities a lighting designer needs to model BY001 against WELL v2, CIE S 026 and IEC TR 63158 — including the ones still awaiting third-party verification.
