IMO the light should not be capped as it would lessen the life of the driver in the fixture.
I reckon the best covers would be fairly tall(just past the insulation) and have a few little holes to help cool the driver heatsink down.

As the cold bites I am looking at the thermal efficiency of our house. We have a large open plan living space that was designed with Melbourne winter in mind. Lots of double glazed north glass, a very thick heated slab and tones of insulation. On the coldest sunny day the boiler (hydronic) never comes on, so by day the room is awesome. My only concern is the heat loss at night through our down lights. we have 16 gimbaled led downlights in the room. If I had my time over i would have only had 4 of them on gimbals, but they are in so now I pay the price of ignorance. I am looking at the tenmat covers mentioned earlier in this thread. The concerns raised earlier were around reducing the lifespan of the expensive led lights. I would like to know if A. anyone has these covers installed and if they help the heat loss they claim to B. if they have any reduction in led lifespan. Given Led lights are still coming down in price, the crossover in cost benefit (life vs cost of heating) is a factor now?
