I apologize in advance that I may have misinterpreted some sentences because I

If the floor is wood, it will yellow due to bouncing and the color temperature
will go down.
Lighting is more reflective than you might think.
Some standard illuminants, such as 'Just', have the shape of a cube.
These products are closed on 5 sides of the cube and only 1 side is open.
However, it can change up to 500k depending on ambient lighting.
A difference of 500k in open space is common.
Of course, the 1/4 power Speedlite is overwhelmingly brighter than standard
illuminants.
However, it should be remembered that 50cm and 130cm have a difference of 2.6
in proportion, and the amount of light decreases sharply by that square.
For this reason,
When measuring lighting, if you cannot completely control the ambient light,
you should measure it as close as possible.
Of course, as a prerequisite, it must be sufficiently diffused so that the
shape of the light does not occur.
