Abstract: A light trolley system for vertical-plane growing that maximizes the coverage area, quality of light, and useable growing area is provided. The light trolley system comprises a support structure and a first C rail secured to the support structure. The first C rail has a first end and a second end. A first brace is mounted to the first C rail and a first light trolley secured to the first brace. The first light trolley has at least one bar light mounted within a light manifold. The first brace supports and stabilizes the first light trolley. The combined first brace and first light trolley is moveable along the first C rail between the first end and the second end of the first C rail allowing the first light trolley to be moved to various locations increasing labor efficiency in the growing area.

Abstract: A lighting system for indoor farming for delivering high intensity light while reducing or eliminating heat loads in a growing environment is provided. The lighting system comprises a lighting housing having a first end, a second end, a first side, a second side opposite the first side, a third side between the first side and the second side, and a fourth side opposite the third side. A first LED board is mounted to the first side and a second LED board is mounted to the second side. A first shroud covers the first LED board and a second shroud covers the second LED board. A coolant passage is formed completely through the lighting housing. A coolant liquid is receivable through the coolant passage. The coolant liquid provides active cooling of the lighting housing from heat created by the first and second LED boards.
