Sunco Lighting 4 Inch Ultra Thin LED Recessed Ceiling Lights Slim, 3000K Warm White, Dimmable, 10W=60W, Smooth Trim, Wafer Thin, Canless with Junction Box 2 Pack - Energy Star ETL T24

Ordered 2nd pair because one of original pair was defective

Easy to install. Bright. Attached Junction box seems to have aluminum wires but are bigger and easier to wire than most led can lights. Just installed not sure on longevity. I pretested them before install.Would buy again. 4 " flush can lights.

Install is a breeze. Brightness great. Color as promised. I like everything about them except that I have had 3 fail out of 14 in about 2 years. The company replaced 2 and were great about it but not sure I want to keep changing them out. Attached picture shows failure mode. For the bad lights the brightness is about 30% for about 10 minutes then they flicker and come up to full brightness.

Looked great when installed, worked exactly as expected but they don't seem to last as long as they should. If you do need to replace a light, it isn't as easy as the plug-in lighting would suggest. Company recommends always replacing transformer and light, which involves wiring work.

Stop working after one week

Love these lights they are beautiful. No complaints about these lights.

If you are considering these for a major layout, buy two of them first and rig them up as a test. I bought a 3000k and a 2700k. They fill the space with light and are so incredibly bright that dimmers are mandatory. They claim to be 60 watt equivalent but seem twice as bright. They are not like a traditional recessed can fixture, where the bulb is recessed 6 inches above the ceiling surface. The LED's are right on the surface of the ceiling so you get the full effect. I have actually changed my layout to use fewer lamps. For example, instead of 6 lamps in a 12 x 18 below-grade basement room with 7 foot ceilings and no windows, I will use 3 lamps down the middle. The 2700k is visibly "warmer", barely noticeable but just enough to take some of the edge off of the bright white. I'll use 2700k in seating and sleep areas, and the 3000k for general lighting. Have not yet tested them on one of the recommended dimmers or tried installing them in actual sheetrock. Only complaint so far is that the metal j-box is a bit tight for wiring. Quick connects would be nice. And the j-box is assembled with absurdly tiny screws. No idea about reliability or longevity, I have a hundred hours on them with no problems. They do not run hot. I plan to keep some replacements on hand.

Product is easy to install. If you use a standard 4" hole bit, which actually drills a 4 3/8" hole, the electrical box fits within the hole. I have purchased the Sunco Cans and LED light inserts before. The light output and look seems the same. The only negative is the electrical box is made of really thin metal. I was actually bending the box when I tried to remove the electrical knockouts because the spot weld on knockout was stronger than the metal of the box. I wish I had the option to pay more for a box that comes on Sunco cans. As others have said, remember to use a connector for around the Romex wire. I used Halex, 3/8 in. Non-Metallic Push-In Connectors from Amazon. The 3/8" is for the 1/2" knockout. I also did not care for the wire nuts. Again I wish these lights came with the push in style electrical wago connectors like their cans do. I ended up using my own wago connectors and they worked fine. These lights are about half the price of installing traditional cans and light inserts. They are also a little easier to install I think.
