Abstract
Lighting control systems are disclosed that have a plurality of current sensors and a microprocessor. A first current sensor in the plurality of current sensors measures a first current of a first LED channel, and a second current sensor measures a second current of a second LED channel. The microprocessor is configured to set a setpoint that defines a maximum current for a dimming profile of a lighting fixture, and control a biological light ratio according to the dimming profile. The ratio may be an M/P ratio of melanopic lux to photopic lux or an OPN5/OPN4 ratio of OPN5 lux to melanopic lux. The dimming profile correlates the ratio to a percentage of the maximum current.
