Notes: This is not a professional photography light meter and you still need to do some calculation to adjust shutter speed & aperture based on the measured light value.

For Your Information:

Lux is a measure of illuminance, the total amount of light that falls on a particular surface. And it can be the result of multiple light bulbs and even daylight mixed in.

Lumens is a measure of luminous flux, the total amount of light emitted in all directions.
The closer to the light source, the higher the lux reading. This is due to the dispersion of light as one moves away from the light source.
