Naturally, I bought these to use with CREE LR6 recessed fixtures. These open box units have the Edison socket. Some had a little dust on them but for the most part good as new. It comes with a paper template to cut around, so I just adjust my hole cutter to size, insert the can, and then lock the clips that clamp down against drywall. The connectors in the wiring box are convenient in that you just need to strip the wire and insert it into the connector and you're good to go. Be sure to insert the wire through a hole in the box first before inserting into the connector because it locks it in tight.
