Physical types: luminous_flux uses wrong base unit
The physical type luminous_flux
is defined like this:
type luminous_flux is SI(lm: 1)
but there is no SI base unit for lumen. It must be defined based on candela. I am not sue if this might be the right definition:
type luminous_flux is SI(cd: 1, rad: 2)
can anyone confirm or deny this?
