Abstract
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.
