I designed these bedside lamps for our bedroom. they each use two gu10 light sockets and one three way pull chain switch. There are links below for parts used. The three way switch allows either upper, lower or both lights to be on. I have thought about changing the design to use e12 bulbs and sockets, but have not yet had the need.
If you have any questions or would like a change, feel free to ask.
