I'm making a desk lamp using a single dimmable A19 7w LED. My questions:

  1. What kind of dimmer/potentiometer can I use?

  2. Can I simply run an extension-type cord from the A19 bulb socket/base into a 110V wall outlet, or is there something special (e.g., power supply) needed?

  3. Is there a newb-friendly resource for learning how to do these relatively simple electronics projects?

Thanks in advance!

an a19 has an e26 base, so its designed to operate on line voltage. so you need to have a dimmable led bulb with an e26 base. dimming will have to be done with a proper ul listed dimmer switch in an appropriate metal device box. you cannot use a potentiometer for this. you do not need a power supply if the bulb is designed for line voltage. you can find hundred of videos on this sort of stuff on youtube or you can try www.make.com
