How did you match the Spectron Area and the Emissive Mesh?
Be sure to always scale Area and Sphere lights using the Light options, not the "standard" item transformations (and 2020, of course).
Spectron Lights in Octane Blender via proxies?
Yes, the vectron light is scaled as you mentioned. I also tried scaling using the other method but the result is the same.
