If any of our lampshades or lamps are being used in USA they can be used with these. (We do need to send you the right diffusers though, with 'big 40mm holes' suitable for E27 or E26). This includes a 'cordset' with E26 lampholder, USA switch and plug.These can be attached to a floor lamp, table lamp or even a hanging lampshade. If for a hanging lampshade then an electrician must cut off the switch and plug before attaching the included spare 'ceiling plate' and connecting to your ceiling.
