Go to a home center and buy a fire rated recessed light cover like the ones made by tenmat for every fixture.
Can you put insulation over led recessed lights.
You d have to buy some remodel ic rated cans and replaced what you have with those before covering with insulation.
In order to cover your recessed light cans with insulation you need to have ic rated insulation contact cans installed regardless of the type of light installed in the can.
Since you mentioned your cans have holes in them they are most definitely not ic rated.
If a led manufacturer says that you can cover the led with insulation be sure to keep your receipt in a safe place in case of premature failure.
This is an important specification not often investigated to the level of detail it deserves.
But here s another solution which you can do yourself.
All led s that say they can be covered have not been tested for lamp life longevity operating under insulation.
