Lamps are presented in the shape of people who caught the light. As you know, light has a huge speed of 299,792,458 m/s and only a black hole can catch it. However, in my imagination, this is also possible for a person, only, of course, in this process he undergoes some spatial changes. The name of the lamps, Athlete, hints that only a trained person is able to do this. For the manufacture of lamps we use metal, stone and glass.
