The name LUX actually invokes the Latin word for "light," which may seem an odd choice for a dark, seductive nightclub filled with the "need to be seen" crowd. That contradiction, however, is easier to accept once we understand the etymology of the name "Lucifer." In Latin, Lucifer comes from the words "lux" (light) and "fero" (bring, carry).
The "Light-bringer" is understandably quite proud of the establishment, which has essentially become a character in its own right since the series debuted on Fox ahead of its move to Netflix. With the exception of a brief sabbatical early in Season 5 — during which Lucifer returned to rule Hell, leaving the management of LUX to Amenadiel (D.B. Woodside) — Lucifer runs the popular club while living in the anything-but-light penthouse atop the venue's building. On any given night, LUX is filled with endless beauties dancing and imbibing while the Prince of Darkness looks on, occasionally treating his patrons to his own dulcet tones.
Though the initially self-absorbed Morningstar has grown over the seasons due to his moonlighting with the LAPD, our favorite fallen angel has always had a bit of an egotistical streak. Thus, we shouldn't be too surprised that he named his business as an ode to himself.
