It is the classic garland luminary type of light we all know. Large transparent bulbs are hanging from a cable (that's why it is called String Light), symmetrically spaced apart. They are also able to illuminate the space below them.
I called them FAIRY LIGHTS. I Decor my room with these lights beacuse they make me happy.
I tried to put a blur effect on background and focus on one blub.
