We are removing our old dropped light fixtures and putting in recessed cans in the kitchen/family room and hallway. I think we will use 5" cans in the kitchen (installed in a 27" soffit). Will the same 5" cans be enough running down the hallway? Hall is 30' long x 42" wide. I was thinking of a can about every 6' (our ceiling joists are 2' on center so that spacing should work out perfectly.)

I am open to switching to 6" cans - I think there will be room in the soffit for either - I just thought the 5" cans looked a little more "modern". I would like to consider CFL bulbs - but the light must be warm not cool.

Your thoughts and suggestions welcomed!
