It all depends upon which trim you'd like to use. IC, non IC, ICAT, etc all
use specific trims. All of these frame in kits use thermal protectors which
shut off power if the units overheat. I don't believe there is a minimum
distance to the framing above the fixture, but I believe they must be one
inch away from framing on the sides

greetings, i will be building a soffit? over a kitchen island and i have a
few questions. first of all i bought a six pack of lighting cans from home
depot (halo brand) and i got the type that can be touching insulation.
their will be no insulation in the soffit so is it okay to still use there
lights or should i get the no insulation type? also, what would be the
recommended distance between the top of the can and the ceiling above? the
soffit will be constructed on the floor and then attached to the ceiling
that has drywall. should i be concerned about heat build-up? i am planning
on using three lights spaced evenly in a 7 foot long rectangular soffit. i
also would like to have the lights hooked up to a dimmer switch.
thanks for any tips, input and advice
