I created this spreadsheet awhile ago to help people understand the attenuation values. If you open it up in Excel, you can change the three values and see how it changes the light falloff.

Keith, the 3rd dialog value...what is E-05?

It's scientific notation, and that's because the number's so small by default. Here's how to change it in Excel 2003: Select that cell, go to Format->Cells... . In the Number tab, change its category to Number, and give it 5 or 6 decimal places. It should then read like normal.

Thanks Keith... you're a genius to come up with this.
