Yes they work, the bulb style from Phillips are excellent and seem to show no problems however some of the retrofit LEDs with a trim kit (very nice by the way with 91cri) like the ones at home depot (made by cree) are awesome from a lighting standpoint but will flicker at certain dimming points. There is a fix on the micasaverde forum which requires wiring a resistor in series for each circuit ( search for "led flickering"). Works like a charm! This is my first post and I've seen UL and insurance questions create wildfire so I suggest if you questions on this matter consult a licensed electrician and your latest building codes.
For your notes I wired these resistors adjacent to the thermal cutoff to ensure additional safety against overheating.
