The bulb is the design
There is no shade to hide behind, so what the fitting looks like at night is decided by the bulb you put in it. A clear filament Edison reads warm and old, a frosted globe reads softer.

Bars on the wall
Light passes out through the cage in both directions and prints a pattern of bars on the plaster behind it. That is the effect, not a side effect.
