How do I install a hampton bay ceiling lamp

Shut the switch off to the existing light, I know it is obvious, but never know. Disassemble the existing fixture, noting the wires inside before you take them apart.There should be a black wire, which is hot when the switch is on, a white wire, which is neutral(return), and possible a green or bare wire that is ground. If you have BX cable, then the metal sheathing of the cable is ground.

Cut each wire,strip, and twist each set of wires, black, white, and ground using wirenuts.

Reverse the process with the new fixture to attach to the ceiling.
