A LED module mount, kit and method for mounting LED modules into lighting apparatuses, in particular for retrofit applications for retrofitting lighting apparatus frames with LED modules. Two module connectors connect to an LED module at opposite sides of the LED module so as to be in a parallel arrangement spaced apart by the LED module. Additional LED modules can be added to form a row of LED modules between the module connectors, with further rows of LED modules being added by adding a third and sequential modular connectors to stack rows of LED modules separated by a modular connector. One or more arms attaches to the modular connectors to connect the connectors to a light fixture. The arms are configured to be rotationally adjusted relative to the modular connectors to provide adjustability for accommodating varying light fixtures. The modular connectors and arms are configured to be adjusted in size, preferably by cutting the modular connectors and arms.
