Hi, guys.

Is it possible to use Backbody Temperature with lights? Not a meshlight object.

Thanks in advance.

If not implemented in 2.5 alpha, I guess not. It has been discussed several times.
A triangle mesh with emission equals one area light.
A ditto triangle at the first‘s backside gets closer to a point light with two light sources. To simulate a point light the triangles‘ surface should be tiny.

Maybe you have it like me and artistic power setting sound rather mystic, then switch and you are able to choose lux, lumen or candela.

I like lumen because this fits good to LED package information and size of the light does not matter.

Thank you, FarbigeWelt. I´ll make some tests about relationship between Light and Meshlight intensities.

Thank you, man! I´ll take a look.
