ᐅ Built-in housing, airtight and square-shaped, for larger recessed ceiling lights indoors

Hello,

does anyone know a manufacturer of airtight recessed housings for ceiling downlights that can accommodate lights about 14cm (5.5 inches) deep? According to energy saving regulations, we need to install these airtight housings in the ceiling and would like to have flush-mounted downlights that are adjustable within a square housing and approximately 14cm (5.5 inches) deep. On the German market, we have only found two manufacturers of airtight recessed housings, each offering a model with a round canister with a maximum diameter of 68mm (2.7 inches) and only about 60mm (2.4 inches) deep, which is far too small. One manufacturer offers fire-resistant square housings, but they cost around 120-150 EUR each.

Has anyone had experience with more affordable solutions available on the market?

Thanks in advance!

Do you really need 14cm (5.5 inches) depth? What kind of spotlights are those? We installed Kaiser 9300-03 ThermoX, which have a depth of 9cm (3.5 inches), but they are round.

Yes, unfortunately. Even the smaller recessed spotlights have a height of 118mm (4.6 inches) and require a 144x144mm (5.7x5.7 inches) square cutout. And the transformer needs to fit in as well.

We have high ceilings and want larger spotlights accordingly, since we think the very small ones don’t fit well. If you want to flush-mount the spotlights in the ceiling, you need that space.

We found a housing, the "Kaiser fire protection box 9435-01", that would work. But at well over 100 EUR per unit, that’s quite an investment when you have many spotlights... 🙁. All because of this annoying energy-saving regulation. In the past, they used to install the spotlights directly into glass wool insulation (which wasn’t ideal). Today you have two nested housings, so the pendulum seems to have swung the wrong way.

I would generally recommend Kaiser boxes as well.

Otherwise, try calling the manufacturer of your spotlights and ask if they know of suitable boxes. Alternatively, you can contact Kaiser with your spotlights and follow up; they are usually quite helpful.
