Described are strip lighting fixtures having a channel defined by a base plate and two side walls, end plates located at each end of the channel, and a channel cover that snap-fits onto the channel. The channel side walls include at least one gripper indentation that releasably engages with at least one tong hanger hook via a snap-fit connection to attach the strip fixture to a support structure. As examples, the tong hangers include hooker clips that connect the tong hanger to a support structure, and the channel cover is contoured to provide additional spacing or relief areas to avoid pinched wires when the channel cover is connected to the channel.
