Reading this thread and searching on line as well, I also seem unable to locate the specifics of how much heat each unit produces

I have 4 L3's on the way right now and my intention is to look at a small farm in the approx 100qty range in the next 6 months, part of the research is to calculate heat output and cooling requirements

Does anyone know if heat output has been tested or of a resource where data of this type is posted?
