A Lum is a small body (or shard) of magical energy which is found in the Rayman games starting from Rayman 2. Generally, there are six different types of Lums that are determined by colour, though in Rayman 3 there is the existence of Black Lums. They usually appear as small lights with insect-like wings, though in Rayman M and the Game Boy Advance version of Rayman 3, Lums look like crystal balls. The name is derived from the French word 'lumière', which means 'light'. Lums in Rayman Kart look like piles of gold money and there are roughly two million of them. In Rayman Origins they will bear limbs, eyes and a mouth and will serve as a currency in the Glade of Dreams.
