Methods and systems are described that enable the simultaneous control of lux, correlated color temperature (CCT), and circadian light (CL) emitted by a lighting system. Aspects also include methods for the adjusting the lux, CCT, and CL with respect to the needs and/or desires of a user, including to provide optimal lighting for light related health. Aspects of the present disclosure also include user interfaces for the simultaneous knowledge and control of lux, CCT, and CL.
