    Abstract: There is herein described a light source that homogenizes the light produced by a large area array of forward directed LEDs mounted on highly reflective substrate, while achieving a low-profile form factor and maintaining high efficacy. The LED light source employs a diffuser comprised of two diffusing layers: a low scattering diffusing layer bonded to the LEDs and a high scattering diffusing layer that is bonded to the low scattering diffusing layer. The LED light source achieves good diffuse illumination with a thin diffuser by making use of a light channeling effect between the highly reflective substrate and the high backscattering from the high scattering diffusing layer.

    Abstract: Various implementations disclosed herein includes a method for operating lighting fixtures in horticultural applications. The method may include receiving a user input of a desired irradiance for a first color channel of one or more lighting fixtures that irradiates a plant bed, in which each of the one or more lighting fixtures comprises at least one light emitting diode (LED) array, determining, for each of the one or more lighting fixtures, a PWM setting of the first color channel such that each of the one or more lighting fixtures irradiate the plant bed at the desired irradiance based on calibration data stored in each of the one or more lighting fixtures, and applying, to each of the one or more lighting fixtures, the determined PWM setting of the first color channel.
