Ceiling light in 4 size variations from 60x30cm to 150x75cm rectangle. Each light is separated and can be positioned in other ways. Separated into multiple parts, base, diffusor and ceiling holder. There is a light to ceiling holder which keeps lights around 0.63cm from the ceiling (visible in the render).(Colored lines in the last 3x renders are only for rendering to showcase thickness and the way that the inside of the light is constructed, not in actual files)
In Blender, light has sharp edges and crease edges to keep the intended look of the light. Subdivided and bevelled.
