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.
