 I am currently doing a rendering for a project. I downloaded a Lithonia light from the mfr's web site (see attached file). But when I do my rendering I get no light out of it and I just get a black rendering. I have checked in my render box that I have interior artificial only checked. I must have missed a check / toggle somewhere. 

 Any ideas?

The Initial Lumens value in the family is 0....meaning it's not putting out any light! Also, see if you can find the photometric web file (the .ies file) for this family, if the manufacturer has one, as the family is currently using the generic photometric file, which is basically an omnidirectional source. If the manufacturer doesn't have an ies file for this fixture, there are some basic ies files for various types of fluourescent fixtures that come with Revit that you can use instead.
