A: Hi - this lamp uses one one maximum 150 watt standard-medium base bulb. You can use an LED bulb if you wish, or a CFL bulb, both of which will be energy efficient. Thank you for the question.

A: Hi - because this is an electrical light the Target site shows it as needing "adult" assembly. There's not much to the assembly. You have to assemble two sections of pole to the base, then add the shade and bulb. Hope that clears it up and thank you for the question.

A: Hi - no, this design does not have a 3-way socket that uses 3-way bulbs. It has a socket that will accept up to a 150 watt standard-medium base bulb and is controlled with an on-off rotary switch. If you are looking for 3-way functionality with this lamp, we'd suggest using it with a cord line dimmer. Doing so will let you set the light output at whatever level you want. Hope that helps! Thank you for the question.
