They are great, I installed them in my basement remodel and they work great with the false ceiling panel. I use 4 inch 3k bulbs. I highly recommend a dimmer as they are a lot brighter than I expected and use push connectors instead of wired nuts. I installed them with a TP-Link Kasa Smart Dimmer and it works great. The only wish I have is that the cable between the light and the junction box is longer so I can securely attach the junction box to the bar so plug-in connections are used instead of Wire nuts due to different wire sizes and that they should come with a junction box grommet.
