1.) get an appropriate bowl of a form/color you like. the required size differs whether you want to use 1 or 3 led-bulbs. i used this ( https://edelrostshop.de/de-at/products/rost-metall-schale-o-... ) and painted it white (got them to deliver 20 pieces without rust). the bowl should be less than 2 kg. the point here is to face the light exclusively to the ceiling while preventing you ever seeing the light sources directly.
3.) if you want 3 lightbulbs, just screw in a a 3-way splitter ( e.g. https://www.amazon.de/dp/B07VH7KKCH/ ). the benefit here is more and more upwards-facing light
4.) the final part is connecting the bowl to the lamp suspension. i just made 4 screws in the suspension and 4 holes in the bowls and connected with basically-invisible nylon strings. getting the nylon strings to be all the same size was tricky but doable.
