Was going to ask the exact same thing.
The item in the Atomic Shop is a yellow table lamp, but it's missing two screenshots and I swear when I bought it, it referred to being a "set." The red "Mid-Century Disc Lamps" described in Week 2 of the events page (https://fallout.bethesda.net/en/events) are nowhere to be found. Which is kind of a shame because those lamps are awesome...
