Abstract
A tunable lighting system includes a first LED having a first spectral output, a second LED having a second spectral output, and a correction circuit including a correction LED. The correction circuit in the tunable lighting system controls the correction LED to emit light that, when combined with light output from the first LED and light output from the second LED, produces a selected spectral characteristic.
