A Latin name meaning “light,” but the word itself, the first three letters in “luxury,” also suggests something opulent and fancy. Like the purchase you finally splurged on that your little Lux will ruin with either bodily fluids or markers, because kids.
Lux is almost impossible to nickname.
Famous people named Lux:
Vocalist Lux Interior (birth name: Erick Lee Purckheiser); singer Lux (birth name: Kate Danson).
Singer Lorde has a song called "400 Lux." You'll have your hands full with just the one, thanks.
