I'm confused:
I am trying to wrap my head around what degree to buy in the source four line. 26 or 36 degree. Gobo colour image will be projected approx. 18 feet with a 750 watt lamp. If the degree is larger say the 36, does the image become not as sharp at the surface it is hitting. Footcandles would be better with the 26 if I understand the chart with a hit image on the surface of 9 feet. If I go with the 36 then the image becomes weaker because the beam is wider at the intended surface of 18 feet and FC is lower. The intent is to project a black and dark green image onto a dull white surface almost grey in nature.
