Question LED Fire/Acoustical Downlight Covers

I'm seeking information on LED fire and acoustical downlight covers like this:
https://tighthouse.com.au/collection...t_posted=true#
or this
https://www.tenmat.com/passive-fire-...nlight-covers/

We are finishing a basement music room. We are unable to afford decoupling the ceiling for soundproofing. Oue ceiling is low, so track lighting seems impractical. Thanks to some great advice I got here, we are looking to use these thin LED downlights.
https://www.amazon.com/Lithonia-Ligh...L53IQ86Pdzd8Xk

We plan to put fiberglass insulation between the joists, but have been wondering what we could do to help mitigate the sound from having to put holes in the drywall for the ceiling lights. I came across the products above.

Are these safe to use in the U.S.?

Is there anything like it sold in the U.S. and perhaps less expensive?

Thanks again!

I've never seen those before. The Tenmat ones have been tested by UL and would appear to be ok for those fixtures. It will make the fixture run a bit hotter and will ultimately shorten its lifespan. They have a link on the site to US distributors or US information.

The other ones from Australia are not rated.

Thanks for checking these out. I will investigate further.

Those fixtures you linked to are IC rated, which means insulation can be in direct contact. I would just install Roxul Safe-n-sound insulation right over the fixtures. It's a heavy insulation product that's made to reduce sound transmission.

It's a good, reasonably inexpensive solution. I don't see any reason to add one of those baffles over the lights as the fixtures are already IC-rated and will be pretty well sealed with the drywall.

Thanks. We do plan to use insulation in the ceiling. If we think we could benefit from the cones, we could add them later. Fortunately they don't have to be part of the initial installation.

Those fixtures and covers seem like a lot of trouble for low profile lighting. I'd just use these fixtures from Progress that mount on a standard 4" octagon box. I like these because they look like recessed lighting, but are much easier to install, are very energy efficient, are dimmable and have the light output of a 100 watt bulb and can be purchased locally if you have a Lowes store near you.

Thanks much for the suggested alternative. Can putty pads be placed on the back of the octagon box like they can on a outlet box?
