Circadian lighting is specified by melanopic light at the eye
The circadian target is 200 EML by day at 75 per cent or more of workstations, measured vertically at eye level (WELL v1).

The evidence behind this sheet
23 factorsheets carry the studies for and against, each with how firm that evidence is.
