I read a very good article about the scale of paint that addressed that the smaller the scale of a model (as opposed to the actual size of the physical object), the lighter darker (full scale) colors should be. The example used was a model of the Titanic and how the bow color (navy blue) would appear an xxx shade lighter if the actual size object was viewed from the scaled distance. There was a mathematical formula of how much white to add to make the correct scale color etc. It seems to me that reverse is true for the scale of lights. I see so many really well built USS Enterprises or Titanics that look like they are toys because the lighting is totally blowing out the shuttle bay or the bridge. Same with aircraft, and the ironic thing is that a lot of LED companies praise their ultra bright properties for modelling but other than rocket engines, lights that are too bright = bad. Nav and interior lights that are too bright totally destroy the scale illusion, So my question is for you expert lighting gurus; is there a mathematical formula that will accurately determine which resistor should be used to tone down ultra bright to scale, whether it be 1/720 or 1/12 scale or anything I between?
