I have 0 knowledge nor experience utilizing ai blades so I can't really comment on what might be the best way to run them as far as mixing and matching along with potential light spill. Since the light is technically longer than the tank is wide, it's safe to assume that there will be some spill regardless of how close/far its mounted (?) or hung from the tank that way unless you angle them slightly assuming that's worth doing.
If I had to make an edjamacated (intentional spelling) guess based on reefbrite bars which seem similar(?) I would opt to personally skip them since they seem to be more of an expensive supplementary light (in my uneducated opinion) rather than a primary light and just go for something like noopsyches if youre on a budget (they are cheaper than the ai blades youre picking) or see if a local shop is willing to work out some deal for however many xr15/30/360x/ap9x you might plan on buying. They are typically map pricing but I've had stores cut me a bit of a deal due to the sheer amount I was buying. Of course there are definitely other lights besides the kessils and radions that work really well but those are just the two led lights I used the most (only utilize noops on one of my tanks just to try it out but others have shown great success with them as far as budget lights are concerned)
One ultra important thing to consider (I may have simply glanced over this if it was mentioned) is what type of coral you plan on keeping to begin with. If it isn't really going to be sps or the random gigantea/haddoni/mag then you can generally add on more lights fairly easily (most of the time) at a later date as it becomes necessary/funds allow.
