To learn more about circadian lighting and how it is measured, please review the Circadian Lighting Appendix L1 and L2.
As a rule of thumb, the required circadian lighting levels may more easily be achieved when specifying high color temperature lamps and light fixtures that display a broader range of the color spectrum as represented by the lamp's spectral power distribution (which can be requested from manufacturers if not already provided). LEDs with higher color temperatures will work better as they meet both of these requirements. That said, other lighting types and temperatures can work as well, depending on how much daylight and/or or task lighting is available to supplement the overhead lighting.
In order to fully verify your lighting strategy, a lighting model that takes into account daylight and/or overhead light should be conducted to ensure that the required light levels are met at all the workstations on the vertical plane where the occupant's eyes would typically be.
