The Red Lums are full of vital energy. Pirates love them. Destroy them and you can take all the Red Lums which they have stolen for yourself.
Packed with vital energy, they restore Rayman's Life Bar;—Manual, Rayman 2: The Great Escape
Rayman can collect these to increase his health when he is in need.—Manual, Rayman: Hoodlums' Revenge
Made up of energy, they add life to Rayman's Life bar.
Red Lums are collectible shards of energy which appear in several games in the Rayman series, most notably Rayman 2: The Great Escape and Rayman 3: Hoodlum Havoc. Along with Yellow Lums, Red Lums are one of the two major Lum types featured in the games.
Red Lums resemble red, glowing orbs. In Rayman 2 they are similar to red versions of Yellow Lums, but in Rayman 3, they resemble atoms, apart from cutscenes where they are in their original winged form. The atom-like appearance recalls the Simple Powers and Double Powers from the original Rayman, which, together with the Big Powers, were essentially that game's version of Red Lums.
Red Lums are the embodiment of vitality, and the origin of all life in the Glade of Dreams.
Role in the games
Red Lums recover Rayman's health. In Rayman 2, if Rayman is injured, nearby Red Lums automatically approach him. Robo-Pirates love Red Lums and collect every Red Lum they can find. It seems that the Robo-Pirates actually eat them; when Rayman destroys a Robo-Pirate, Red Lums are often found inside them. Similarly, the defeat of a Hoodlum in Rayman 3 releases a Black Lums. If Rayman uses Grimace on a Black Lum, it will revert back into a Red Lum. In the Game Boy Color version of Rayman 2, a Red Lum completely restores Rayman's health.
In Rayman 3: Hoodlum Havoc, the Glade of Dreams is attacked by an army of Hoodlums, sack-cloth creatures piloted by Black Lums. Each of these Black Lums – including their leader, André – is a corrupted Red Lum.
Red Lums appear in the Game Boy Advance version of Rayman Raving Rabbids. In this game, they resemble red Tings. As in Rayman 2, these Red Lums restore Rayman's health when he collects them.
