How does Unity interpret light intensity in glTF file?

for example if I have:

- point light in Blender with power 10W

- exporting that as glTF will convert it to intensity = 543.514... (which is correct, as glTF stores light intensity in luminous intensity in candela (lm/sr))

- importing to Unity using UnityGLTF, the point light's intensity is 173 and the range is 100000?
