For lamps, the method we usually use is using our 18 gauge all-purpose shielded power cord. They come in 6 feet and 12 feet lengths. We often splice those cords in the bottom base of the lamp and ground the metal body of the lamp (if there is a metal body) by attaching the ground cord to the nut on the bottom of the threaded metal tube at the base of the lamp. There are many different types/configurations/styles of lamps, but there is usually a way to get it done somehow :)
We are working on a shielding material to retro-fit cords that can't be replaced. We hope to have a kit available soon.
