Final answer:
The minimum amount of lighting in a resident bedroom is typically measured in illuminance and is recommended to be 500 lux (lx) for desktop lighting.
Step-by-step explanation:
The minimum amount of lighting in a resident bedroom is typically measured in illuminance, which is the amount of light that reaches a surface. According to the Occupational Safety and Health Administration (OSHA), the recommended illuminance for desktop lighting is 500 lux (lx). Lux is a unit of illuminance that measures the amount of light per unit area.
For example, if the lighting fixtures in a bedroom are hung 2.50 meters above the desktop level and provide only 300 lx, they would need to be lowered to a height of 1.22 meters to provide 500 lx on the desktops.
