What is Luminous Intensity and Photon Energy Calculations about?

The document provides calculations for luminous intensity and luminance based on luminous flux and distribution over a sphere or hemisphere. It states that a light source emitting 500 lumens has a luminous intensity of 132.63 candela, while a 2000 lumen source has a luminance of 141.47 lux at 1.5 meters. Additionally, it calculates the energy of a photon of infrared light at 1.55 micrometers to be 1.28 x 10^-19 joules.
