A: Hi - there is no diffuser in the bottom of the shade on this design, the drum shade is open at the bottom. Thank you for the question.

A: Hi - no, the cord is not part of the shade, but the shade is not a traditional spider with a harp and finial. Since the shade hangs down it has an uno style fitter, so you would need to find that kind of shade as a replacement. Thank you for the question.

A: Hi - sure, you can use a smart bulb with this floor lamp design. Should not be an issue, but check the specifications of the smart bulb to make sure. Thank you for the questions.

A: Hi - this has an on-off foot operated switch on the cord. Thank you for the question.

A: Hi - yes, you could use a line cord dimmer with this design. Thank you for the question.

A: Hi - yes, the lamp shade is open at both the top and bottom. Thank you for your question.

A: Hi - sure, you can use an LED bulb with this lamp. The lamp's socket can accept up to a maximum 150 watt standard-medium base bulb (not included). If you are planning on using the lamp with a dimmer, just make sure the LED bulb is dimmable and compatible with the dimmer. Thank you for the question.

A: Hi - the shade is not easily switched on this design, as it is a special downbridge style shade specifically made for the lamp. You could perhaps have the shade recovered, but there is easy replacement option. Thank you for the question.
