Recessed porch lighting - X-post
We're redoing our porch ceiling (vinyl beadboard was run the length of the porch in 12ft sections just nailed to joist 16" OC so it sags). We're putting plywood up on the joists (hate to lower it 1/2" but carpenter says it's faster, easier, cheaper than blocking) and then reinstalling the vinyl cut to run front to back instead of side to side. While we're at it, I wanted to add recessed lighting. I got a contractor 6-pack, rated for damp locations. We have 48ft to cover, but the middle 8 ft is where the stairs/door/coach lights are, so I'm thinking 3 recessed lights to the left and 3 to the right, over the seating areas, none in the middle? The joists are 16" on center, so should be 36 of them though they may not be centered on the front door, but they should fall roughly 6ft 8in apart, and they are 6" cans. So about 6-7ft apart, depending on where the joists are (centered say at 7'1", 13'7", 20'3" from garage, then about a 6'10" gap, then start again on other side of the front door).
Maybe not the best pic, but shows the whole porch
I was thinking since it's 6ft 3in to the inside edge of the columns, we should put the lights about 3ft from the wall so centered (give or take 1.5") b/t the columns and the house? Or should we move them out toward the front edge a little more? How much? And finally, separate switch or can we tie them into the coach lights (easier)? Dh thinks there might be times when we'd want to turn on the coach light only, but I don't know if it's worth the hassle of fishing wire through insulation and rewiring a switch (I'd steal the one for the garage coach lights since we never turn on the garage lights from the front door, I want to put a switch in the mudroom for the garage lights, but it would be easier not to have to get the new lights run to the inside switch, just tie them into one of the exterior lights).
I have 12/2 Romex (and also 14/2 somewhere if I can find where DH put it). Says for interior use. That's what electrician put in our (full-soffited, uninsulated) garage, so would that be OK to use in the porch ceiling?
