Abstract
This disclosure includes kits for retrofitting, or replacing with new, light fixtures using an existing troffer, without using a troffer, and/or including a troffer. Some kits include a frame for a light fixture having a first end, a second end, and a frame length extending between the ends, a first mounting member coupled to the frame and configured to extend beyond the first end of the frame, and a second mounting member coupled to the frame and configured to extend beyond the second end of the frame, where the mounting members are configured to support the frame relative to the troffer. Others of the present kits have a trim configured to support the frame relative to a T-bar support of a suspended ceiling. Some kits have a processor configured to control the light fixtures, and some kits have one or more sensors configured to detect events or environmental characteristics.
