    Abstract: A horticultural luminaire includes a first and second horticultural light sources to provide growth lighting to a plant at a first and second wavelengths. A control unit provides first lighting control signals to the first horticultural light source to modulate the first growth lighting and provides second lighting control signals to the second horticultural light source to modulate the second growth lighting. A LiDAR sensor is connected to the lighting control unit to receive the first and second control signals, and having optics to detect reflected first and second growth lighting to determine the distance from plant to sensor and a biometric property of the plant from the received first and second control signals and detected first and second reflected second growth lighting. In some implementations the LiDAR sensor and first and second horticultural light sources are integrated into the horticultural luminaire.

    Abstract: Embodiments disclosed herein describe systems and methods for heat sinks within light fixtures. In embodiments, the heat sink may be a passive system that creates a cross-flow thermal management system to dissipate large amounts of heat in a slim light fixture. Embodiments may utilize a series of wings assembled in a linear design that are positioned perpendicular to the length of the light fixture to preserve the cross-flow heat sink.
