This is only a question this isnt a project. If you have a 100 ' by 150' retail store. The store will have 300 fixture w/ 2 ballast@120v with .75 amps. Once demand load is determined Would you use the larger of the two for the service demand factor? if so where is that located in the NEC. Thanks

Take a look at the first line of article 220.12; not less than specified in T220.12.

So yes, calculate both, and take the larger of the two.

I hope that helped.
