Number of Recessed LEDs in Living Room?

Hi,
I'm trying to figure out how many recessed LED lights we'll need for our 14x16 living room. The contractor eyeballed the room and said six, which we'd run basically in a rectangle that mirrors the shape of the room, but now I'm thinking I'll add one in the middle (or maybe even bump the pattern up to three rows of three lights). Would this be too much?
These will be the Home Depot Ecosmart 6 inch light (the Cree CR6 equivalent). 8 foot ceilings.

I realize there are formulas out there that specify spacing, but these lights seem to throw wider light patterns and look brighter than standard recessed lights.

Thanks!

 

Even though the package says it's equivalent to a 60 watt incandescent bulb I feel it is closer to a 40 watt bulb so I would error on the side of more lights.

 

I have used these exact lights. They are very close to a standard 65 watt incandescent but not quite there. I also suggest on more lights. You can always dim them down.
