TYPE 3 DIST. IESNA

THIS IS A TYPE 3 DISTRIBUTION, STREET LIGHTS, SOME PARKING LOT LIGHTS AND WALLPACKS USE THIS SHAPE OF LIGHT . MY GOAL HERE IS TO SHOW THE HAND FULL OF LIGHT SHAPES USED BY IESNA TO DEFINE ALL LIGHT THAT WE SEE. IF I CAN PRINT THIS SHAPE AND PUT IN A STUDENTS HAND THEY WILL NEVER GUESS AGAIN AT WHAT SHAPE IS CORRECT FOR A GIVEN APPLICATION.
