É obtida principalmente a través dunha lámpada fluorescente sen a protección do compoñente que a fai emitir luz visíbel. Unha lámpada fluorescente común contén un gas inerte (<a href="/wiki/Mercurio_(elemento)" title="Mercurio (elemento)">mercurio</a>) que, na pasaxe de electróns, emite radiación na lonxitude de onda do ultravioleta. Esta radiación liberada "bate" na borda da lámpada que é revestida internamente por fósforo. O fósforo excitado coa enerxía recibida reemite a enerxía en lonxitudes de onda visíbeis (branco). A lámpada de luz negra non conta co revestimento de fósforo, deixando así pasar toda radiación ultravioleta.
