Wanted test indirect lighting with this lamp ( https://www.yeelight.com/en_US/product/luna )
I have some floor standing lamp (ikea?), it is purposed to use with E27 bulb, so...
You can choose from two adapter, one goes to in E27 socket, second one goes around E27 socket (then you can take power to lamp from socket, IF you have know-how for wiring, I don't take any responsibility or liability!)
It is not pretty, but working =)
For mounting i used:
2x M4x12mm bolts
4x 4.3/15mm washers
2x M4 nyloc nuts (with these, you should use 2-3mm longer bolts)
edit: 270318: just uploaded stl what has holes for wires and couple new pictures. Use supports for wire hole!
You may play with settings.
