We have these installed in our kitchen. They are dimmable and work well - with one caveat.
That being, they emit a substantial amount of RFI. So if you listen to old fashioned FM radio or watch OTA television nearby, expect interference.
After discovering this I opened up each fixture, and added a snap-on ferrite core over the wires. Unlike magnetic wrist and ankle bands, these actually help. This cut the interference by about 2/3.
Edit: these are ferrite beads, not cores. Oops.
