Abstract
A method and apparatus for a horticultural light for use in an indoor horticultural facility that produces broad spectrum white light with variable correlated color temperature (CCT) so as to better simulate various aspects of the sun, such as the multiple phases of the sun, aspects of the sun in all four seasons and latitude of the sun. One or more rows of fixed-color LEDs is used to obtain even wider ranges of CCT values, such as the use of red and/or blue LEDs. Even broader spectrums are achieved by utilizing LEDs that emit differing wavelengths within a particular color spectrum, such as a channel of red LEDs that emit two different wavelengths within the red spectrum and/or a channel of blue LEDs that emit two different wavelengths within the blue spectrum. Sensors with feedback control maintains the light within constraints defined by a light prescription database.
