Diagram of a Spotlight

Post by Fletch » Tue Sep 28, 2010 9:16 pm

This diagram is to help a beginner understand what all those numbers mean for their Twilight Spotlight.

Things to remember when laying out lights in Twilight Render Plugin for SketchUp:
  • For a space between 8-9 feet tall (about 2-2.5 meters) assuming that a spotlight of power of "1" is a 100 watt light bulb is a good place to start.
  • Spacing your light fixtures out to match how you would do so in real life is essential.
  • Loading an IES data file for a Can Downlight into your spotlight inside of a can downlight in your model is the fastest way to get great-looking lighting.
  • Remember that the default color of the light source (even IES files) is always white, so setting the correct color for your light source is essential for realistic results.

Thanks Fletch,

This tells us newbies directly what is meant by fall off and hot spot. I tested it by myself and came to this conclusion.
But this picture gives directly an idea and losses a lot of questions :whoot: :clap:
