Wiring porch light fixture.

Support the fixture with a wire coat hanger. Wire the switch install a bulb and test. Caulk around the base. Some wiring may vary however this is the most common wiring scenario for a 120 volt light fixture.

However it s likely that the light fixture was mounted in the middle of a stud cavity which makes mounting a box that can support the weight of the fixture more difficult. Light fixtures with more than one lamp may have a pair of black and white wires for each lamp. Make sure the power source is turned off. Electrical wiring at the light fixture is typically made by connecting together the wires of the same color which are commonly black white and the bare ground wire or green ground wire.

Low voltage lighting systems must be listed by an approved testing agency as an entire system or assembled from individual components that are listed. These connect to the black and white wires in the electrical box with the provided larger wire nuts. Low voltage light fixtures luminaires must be no closer than 5 feet away from the outside walls of pools spas or hot tubs.
