Ceiling light in 4 size variations from 60cm to 150cm circles. Each light is separated and can be positioned in other ways. There is a light-to-ceiling holder which keeps lights around 0.5cm 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. Area lights are parented to each individual light and can be used very easily.
