Spotlight "Radius" should be focal length

The spotlight has a radius function that I don't think is as intended. Changing the radius just artificially changes the length the light projects from the spotlight. Obviously this is not how light works. The best practical example would be a flashlight with a focal length adjustment, like a Mag Lite. When you twist the two parts of the flashlight it adjusts the focal length or where the focus of the beam is. The practical upshot of this is that when you focus it out further, the beam cone gets narrow and the focus of the light is further out and makes a narrow "longer" beam. When you focus it shorter, the beam cone widens and the focus of the light is closer in. So you can flood a closer wider area with light or you can focus a narrow beam of light further out.

The spot light does not work this way at all. The radius adjustment should either be removed, because what is the point of a light that does not reach as far as it can if you cannot flood a closer area with light. Or, and this is the best option, it should be made to work as an adjustable focus light should work. Flood a wider, closer area with light or focus a beam of light further away.
