Abstract
A load control device for controlling a light source may be configured to control a target color temperature near a low-end intensity level to converge the color temperature towards one or more color temperatures. The light source may include first and second emitter circuits that emit light having first and second color temperatures, respectively. The load control device may control the first and second emitter circuits to cause a present color temperature of the cumulative light emitted by the light source to be controlled towards the target color temperature. When a target intensity level is less than a threshold intensity level, the control circuit may limit the target color temperature according to at least one limit curve that causes the target color temperature to converge towards at least one of the first or second color temperatures as the target intensity level decreases towards the low-end intensity level.
