Difference between light_enviornment and light_directional?

I have been reading up on both light_enviornment and light_directional and I cannot really figure out the difference. From what I can tell they both emit light from a skybox that has no falloff, both can have their brightness and intensity set, as well as their pitch and yaw.

So what differentiates them from each other? When should I use one and not the other? Should I always use both with matching settings?

Light_environment is both a light_directional and a skylight(light emmitted from all directions essentially the sky is a giant light)

while a light_directional emits no light from the sky, it’s just a directional light.

Light_environment is what you should use for nearly everything.

Thank you!
