Lux es el tercer disco del grupo de rock psicodélico peruano Traffic Sound, lanzado en 1971 por el sello Sono Radio.
 
Recorded at the end of 1971, this was the last album by this legendary Peruvian band. Compared to their previous recordings, the Latin and Andean folk influences were much stronger here and the lyrics were more politicized, painting a picture of the social and economic turmoil of Peru in the 1970s. Incredibly, due to a workers' strikes at their label, the master tapes were lost until 1996 when they were finally found labeled as "Andean folkloric music". Featuring the flute and tenor sax playing of Jean Pierre Magnet, the only member who would go on to be a professional musician and a world famous sax player.
