I'm finishing the ceiling on my basement. I'm planning to insulate the ceiling with the Roxul Safe'n'Sound Fire & Soundproofing Insulation. It is 3 inches thick so it only occupies the upper 3 inches of the bay.
I was planning to use IKEA's BLIXT recessed spotlight. However, I have a concern with its clearance requirements: top of luminaire to overhead building member 0.5"; luminaire center to side building member: 12". My joist spacing is b/n 11" and 15" so I can't possibly satisfy that. Those requirements sound a bit extreme, don't they?
From what I could quickly research I think these fall into the "Marked Spacing Type Luminaries" category, according to:
Any thoughts? Can I make it work? I like these lights: they look great, are only 35W and cost $19 for 3 pack which is an unbeatable price.
