Composite light sources and methods use a low-blue component light source emitting first substantially white light and a high-blue component light source emitting second substantially white light. The second substantially white light has a greater correlated color temperature than the first substantially white light. The first and second substantially white light combine to provide substantially intermediate warm-white light. L'invention concerne des sources de lumière composite et des procédés utilisant une source de lumière à faible composante bleue émettant une première lumière sensiblement blanche et une source de lumière à forte composante bleue émettant une deuxième lumière sensiblement blanche. La deuxième lumière sensiblement blanche a une plus grande température de couleur corrélée que la première lumière sensiblement blanche. Les première et deuxième lumières sensiblement blanches se combinent pour fournir une lumière blanche chaude sensiblement intermédiaire.
