What are Photometric units

Photometric units are what light intensity is measured in, using LUMENS and CANDELAS and so on. When measuring light you can use industry-standard luminous intensity distribution files like:

  • IES
  • LTLI

 all these are available from most lighting manufacturers. Lighting can be measured and set to how you want it using these techniques in both a 3d enviroment and the real world.
