What do you do when a fixture uses them? Do you strip and wire nut them?
Just wanted to know because I may do a couple more in the living room.
Yeah... I put in Progress cans, and when you add -QC to the end of the part number they have quick connect things-a-ma-jigs on them like you're talking about. I use them if they're preinstalled, but I don't brag about it. Those type of connectors, not unlike back stabbed switches and receptacles, only contact the wire by a barb. I guess they're fine for a few lights, but if you start drawing some higher currents through them, I just don't trust them.
In fairness, I have never seen this type of wire nut fail in the field. Many guys call these "Wago's", after one popular manufacturer. I have seen plenty of backstabs fail, but I have not observed any failed Wago's. I guess that might be mostly due to their limited usage.
In the end, they are UL listed and are supposedly fine to use. I'm just not jumping on that bandwagon.
