9W 4Inch Slim Recessed Ceiling Light 650LM 5000K Daylight Dimmable Airtight Downlight with Remote Driver (5000K, 4INCH-4PK)

It is the perfect retrofit, if you don't need to prevent air flow. For convenience, I give it 6 stars. Same for brightness and color temperature. It is just a little slow starting and as long as you don't mix with other lights it is probably less noticeable.I have had one fail of a different manufacturer, but otherwise these things are great.Throw out the pattern they sent for the cutout. It is too large and won't keep it secure enough to not reveal the hole. I've included my pattern, which if you are careful, will closely fit and won't show any gap. Just print it and make sure it is to scale as shown.As I've added so many of these things to the house I may seal them from the top to prevent A/C loss.

Sure, they installed easily and looked nice but....they didn't even last 6 months! The home is used seasonally so, I'm being kind with saying it lasted six months. Installed by August, and used for about a week. Returned in January, and used the lighting for 5 more days. Wow, why bother with these with this short of a usage life....don't bother.

Easy install. My biggest gripe: the metal is super thin, be careful when knocking out the holes and when clamping down the wiring.

excellent product. super recommend the purchase.

Great product

I couldn't ask for anything better

Love it!!

Well worth it
