Re: Getting closer to the answer

Kind of, see questions I have are can I operate a 7' parabolic antenna on those lights for example? Is there a way to know instead of just trying? I am looking for a general thumb of rule, as indicated in my first post, to put it in terms of a mathematical function:

Required Wattage = f (Light source size, Distance, F-stop, etc)
