Here's a bubbly lampshade + base kit compatible with the official Bambu LED Lamp Kit - MH001.

Prints best with either translucent or light/white filaments. PETG tends to be more translucent compared to PLA as well. 

Uploaded print profile is for 0.8mm nozzle, but I think the 0.4mm prints allow for more light transmission given the thinner spiral walls.

The bottom shell layers parameter will need updated per nozzle to ensure the female base prints all layers. This also adds more weight to the base, giving it a nice feel.
