wdupre, that was my first thought, so before rendering my second image (above), I basically just turned up the light intensity and focused the lights more directly. It did at least give me a better render than the first one.  Been learning the basics of the program and haven't had the need to render much until now, so I haven't really spent much time on lighting to this point. Looks like I'd better take the crash course! :-)

You mentioned "their colors", and I did notice at the properties/parameters/dials, the default lights do have colors blended. Just haven't learned how to work with all that yet.

Btw, the lighting properties/parameters screengrabs shown are the "default" settings poser gives me when I open the program, these are not settings I've changed at all.
