The typical pot light installation can cost anywhere from $500 – $1500 depending on how many and whether or not there is an available circuit to use.
Pot lights are not necessarily hard to install. At times, the installation of pot lights requires attic access to avoid having to cut the ceiling to make way for the required wiring to power the devices.
Pot lights are installed from the attic more times than not to avoid drywall damage. Depending on where the power source is located and the number of pot lights, drilling through the joist is required to bring power to each pot light when attic access is not available.
Pot lights can be added to any ceiling, you just have to find a way to bring power to them.
