I am brand new to artificial lights. I have an exterior light that WORKS when I render- but I wanted to try a different one. So I simply loaded the wall light that comes with Revit 2011. Still has the same sun and artificial lights for render and all I did was put this light on the wall and set the watts to 10,000 just to see if it would light up- but it doesn't.. It is listed and checked as "on" under light groups for render. See the image of the instance and edit properties of this light and please tell me what I need to do to make it work. Thanks
