I agree with 480,,,you have not given enough info. You lay the lights out according to the room. It's something you get a feel for. In any given house, they are gonna be a different distance apart in every room, unless the rooms are indentical, but even then, what's in the ceiling can affect the placement,,,,so every room gets it own design. Lay it out on the floor until it looks right. Then use a laser plum.Just want to hear other peoples thoughts on placement of 6" recessed cans with 65 watt, BR30 type floods. How far apart do you place them?

Very philosophical, almost Zen-like.I like to lay them out on the floor first. When the layout is right a feeling of calmness and satifaction will rest on your mind. This can take days at times. Hang in there. The light knows where it wants to be, you just have to listen.
