cell shading doesnt really use real light sources. theres sometimes only the sun, and maybe torches in caves. the torches will through a round, hard shadow, and the sun often makes a smooth super soft shadow for the environment. the characters and items have hard shadows too, and doesnt really get brighter with a lightsource. They often have 100% lighting anyway.
look at those screens:
you can see that the torch makes a hard light, but the sun doesnt:

and at night its the same, the windows doesnt produce light at all:

thats why i prefer cellshading, its easier with lighting
