LLF (Light Loss Factor)

The light loss factor (LLF) is a measure of how much light is lost when passing through different materials. It is calculated by the amount of light entering an area and the amount leaving it. The LLF can be affected by factors such as absorption, reflection, scattering, refraction, and transmission. In general, higher LLF values indicate that more light is getting through, while lower LLF values indicate that less light is making it through.
