Hello,
we are going to build our single-family house this year, and I have already been working on the planning for several months. Last night, I bought LED recessed downlights for hallways, dressing rooms, the kitchen, etc., and now I am wondering whether I can simply install them into the drywall or if I need special covers due to heat and fire safety concerns. Maybe someone can provide detailed information on this? Thanks in advance.

Ok, that would certainly be the best solution. Unfortunately, the back boxes cost more than the spotlights. My next consideration would be whether the box can fit easily, especially in terms of height. I’m not yet sure how much the drywall panels will be lowered, but I think only a few centimeters (inches). Is it possible to compress the insulation and vapor barrier that easily?
The standard ThermoX models are expensive, but the LED version is available for under 10 euros, can be retrofitted through a 74mm (about 3 inches) hole, and requires a depth of 6cm (about 2.4 inches).
There are also very slim downlights available (for example, from Osram with a 13mm (about 0.5 inches) installation depth), but you already have the spots.
Without the housing, the spots hang directly in the insulation and push the vapor barrier upwards. Without any protective measures, this can lead to serious issues because even LED spots can get quite hot. You should at least check the datasheet for the spots to see what housing temperature they reach and if there are any installation guidelines.

Yes, that would probably work in some way, but I don’t want to cut corners on a new build at any cost. Since I only have about 40 recessed lights in the house, I’d rather spend the money on high-quality flush-mounted boxes. Besides, the silicone cups are also not airtight.
