I am not the original poster, but, in this case, just to keep things simple, let us figure that the original posters question is: Buy one light that is $250, or three lights that are $83 each,
and that the three lights that are $83 each will not be big/large, and the one $250 light will not be small. I think we can figure this, because the original poster did mention that the three lights will be "smaller" and also, that the three lights will be "mid size".
So, what we have in the original post is:
Buy one, big, and/or bigger than mid size light, at $250, or:
Three, smaller mid size lights, at around/or about $83 each.
I think the original poster has supplied enough information for us to figure out what his question is.
