The lighting unit of Coohom used to be “%” by default, which is a specific unit of the lighting system.
Now it is possible to modify the lighting unit in the preferences. We updated a new unit lm (luminous flux unit). Designers can set lm or % according to their own habits.

Go to floor planner > help > preferences > rendering.

After setting, the new unit can be seen in rendering > ambient lights > customize, when modifying the light parameters and sunlight parameters.
