Inquiry about lighting DIAlux

Good day my dear members

I find myself doing a project for industrial lighting, is an outdoor lighting project.

I have to use a sports reflectors of various powers, such as 70 W, 150 W, 250 W, 400 W, 1000 W. HPI or MHN

I have a basic doubt lighting. each reflector offers a different lumen value depending on the symmetry of their Isolux curve. Basically, the question is, How I can determine the minimum height for each type of reflector?. and, how do I determine the horizontal spacing between each luminarie depending their lumens value.
