lighting design

(OP)
Hello.  A developer has asked me to verify if the lighting design for a condo parking lot is sufficient under IES regulations.  He has sent two different choices for lighting fixtures and a .ies file for each one.  I am supposed to run these files and make my decision.  I learned that there needs to be 2.4 footcandle average, .6 minimum, and a 4:1 uniformity ratio for these fixtures.  My trouble is that I had trouble opening/and using the free software I have downloaded for lighting design, that can open .ies files.  Any recommendations as to a good free program to d/l to try and figure out which fixtures adhere to the IES regulations?  I was able to open one of the files, but did not undertand all the information presented and how to analyze the results.  Any advice will help, as I am new to lighting design.  Thank you.

RE: lighting design

I would suggest that you either work with a vendor who has the software necessary, or hire a consultant who has the software and knows how to use it.  Good point-by-point lighting calculation software does not come cheap.
