Hi,

Sorry ... NO !!!

True .. this is how it will work in AutoCAD .

That seems too wide-open -- I expect in a lot of cases there would be multiple possible solutions.
One thing that could get you part of the way there is DivideMeasurePlus.lsp, available >here<. Its MEA+ command gives you the option, not available in regular MEASURE, to center the results on the path, rather than start from one end. At this prompt:
Standard measure alignment or Center on path length [ S C ]? <Standard>:
pick on the C option, or type C.
So for one direction, you would draw a Line across the room [or use a wall Line if there's one that goes the whole distance in one piece], and use MEA+ to place your light-fixture Blocks at a specified spacing. But it can't decide within your spacing range what to use -- you would have to choose a spacing, try it, and see whether the end Blocks are at an appropriate distance from the ends, and if not, try again with a different spacing.
Having established the positions in one direction, you could draw a Line across the room in the other direction, and use, instead of the Blocks option, the Selection option [also not available in regular MEASURE] to pick the whole row of fixtures placed in the first direction, and place them collectively in similar fashion across the second direction.
