Hello Everyone, I am trying to create a very simple LED light similar to the image below. In essence, I would like to mount 3 LED lights (or more) in a metal tube that is approximately 1/2 inch in diameter. I would like to be able to hook the lamp into a regular wall socket for power. I have no experience with circuits, but would love to learn. I would really appreciate it if someone could tell me what parts I would need to make this happen. I am trying to minimize the cost and would like to be able to fit all the necessary wiring and parts inside the tube (so none of the circuitry is visible from the outside). Any tips are greatly appreciated. Thank you!
