Abstract: A method of controlling a correlated color temperature for light output by a lighting device including a dim-to-warm circuit having a first light channel and a second light channel. The method including receiving a current input; measuring current of the current input to obtain a measured current value; and determining a light control value based on the measured current value. The method further including using the light control value, determining a first current value for applying a first current to the first light channel and determining a second current value for applying a second current to the second light channel; and providing the first current to the first light channel and providing the second current to the second light channel to obtain different desired correlated color temperatures for the light output at different ones of the light control values.
