The smaller (point-shaped) the light source is, the stronger the shadows, because the light only comes from one direction. A clear light bulb of a conventional type e.g. will create strong stripes because the filament is a very small light source. On the other hand, if you use a globe lamp with a frosted glass diffuser, the light source is many times larger. The light comes from different directions and in this way causes the shadows (depending on the actual size) to almost disappear. Here, too, the tastes are different. Some customers send pictures of striped rooms. Others choose the frosted glass version. Filament LEDs are somewhere in between, as they have usually various sources.
