12-Pack 4 Inch Ultra-Thin LED Recessed Lighting with J-Box, 3000K Warm White, 10W Dimmable 700lm Brightness LED Downlight, ETL & Energy Star Listed

I don't leave reviews for a lot of items I buy but I've been so pleased with these lights that I felt the need to. I have installed about 30 of these throughout my house (living room, bedrooms, office, garage, kitchen, hallway) and they are awesome. They are a massive upgrade from the existing fixtures I had, especially when considering the cost and time to install. They are extremely bright so make sure you install with a dimmer to get the desired lighting (I used the Lutron DVWCL-153PH-WH, White). For example, I installed 8 in my living room which has 8' ceilings and is 14'x18'. I spaced each light about 4.5' apart and I dim them down to about 75% for everyday use. In my opinion 3000k is the only color suitable for indoors, 2700k is too yellow and 4000k+ is too white (best for the garage). Whatever suits your taste, just make sure you buy all the same color throughout the house for a clean, uniform look.The specs state you only need a 6.02" ceiling opening. When I measured one of the backs before I made my first cut, it was more like 6.25". I've cut all my holes to 6.25" and these lights still have a snug fit with no gaps. I love that they are rated for contact with insulation. I had a few existing traditional canned lights in the kitchen that required a thermal barrier which I always ran into when moving around the attic, forcing me to fish out the blow-in insulation that inevitably found it's way into contact with the fixture.I would buy these again and would recommend them to anybody looking for a quality light that is reasonably priced and easy to install. I'll upload pictures in the next few days.

I originally thought I'd get the 5000k because I like white things, but I was wrong. 5000k was too blue. After getting the 4000k, though I was super happy. The lamp is an incandescent for comparison. When I want a homey mood I turn off the recessed lights, but when I want to work the recessed lights are perfect.First, these are really easy to install. It's totally do-able to chain these along, with the romex going in one knockout, romex going out the other knockout, and connected to the light with the supplied wire nuts. It's a bit of a tight fit in the box, but it works. After it's wired in and the box is tucked away, it was easy to use the supplied template to cut a hole in the drywall, though I'd suggest cutting on the outside of the line instead of inside. It was a pretty tight fit when I did it. With the hole cut, you find the box (hopefully you measured everything right and marked the right spots when you did all your drywall and paint), and plug the light into the connector, then fold the springs back and slide it up into the hole. The springs are super strong and there's no issue with it holding the light tightly against the wall (I used 5/8" drywall).The string of lights works great with my Leviton Decora Smart Wi-Fi 600W Dimmer. For the most part I usually keep the brightness around 30%. All the way to 100% is pretty intense, though I may have gone a little too dense (roughly 6' spacing between all the lights).I was a little worried that there's be some whine or buzz from a transformer or capacitor doing voltage switching, but these things are perfectly silent.Inspection was a breeze. For rough-in I routed and stapled all the wire with uncut loops where the lights would be, and wired up a practice box with spare wire to show the inspector. He was interested in these ultra-thin lights because he hadn't seen them before, but was satisfied. Then for final inspection he never looked at the final wiring and only made sure the dimmer worked correctly.

This is the first time using this product. Reading through the reviews, I had some concern about the clips not being strong enough to hold the light tightly against the drywall. It was a non-issue as the springs held the unit in place and tight against drywall. The installation was simple. Only small gripe was the junction box didn't have push-in connectors, but wiring nuts were supplied, which was fine. I bought the warm light version. Excellent color and plenty of lumens. A slight hum when dimming the lights low which is to be expected. Only negative was if you dim the lights low and then turn off, they will not turn back on at that low level. You simply increase the dimmer and they come to life. Not a big deal, but something I thought should be mentioned. Overall, I am very satisfied with this product. I will use these at other projects where IC rating is not required.

Summary: Lights are easy to install, bright, dimmable and clean looking. Worth the money. Now I want to put more around the home. It took me like 10 minutes per light to install.I originally put can light in during construction but they didn't allow me the room to insulate above them how I liked so after some looking around at Lowe's and online at comparable models (Halo) I found these on Amazon. I purchased the 4" by mistake, thought I wanted 6" on my cathederal ceilings. I kept the 4" because I liked the idea of them being less intrusive on the ceiling. Glad I did. These little things put out a lot of light.I temporarily installed them to finish some construction as can be seen in the pic.

These are rather nice fixtures. Color temperature and lumens listed appear accurate.Packaging is appropriate and efficient.Junction boxes are on the flimsy side, but manageable. Push-in wiring connectors would be nice instead of wire nuts. Low-voltage connection wire would be better if it were 5-10 cm longer, but also manageable.Dimming range is actually quite impressive.Longevity is impossible to comment on, but time will tell.

The media could not be loaded. No flicker as seen on the video, They sell various k values at different prices but the switch on the box selects that and it seems to work fine.
