UPDATE: I checked reviews on the LOWES website - the Utilitech bulbs do this for everyone - they are just a crappy product. *** I have replaced several MR16 halogen bulbs in my kitchen with Utilitech MR16 LEDs. Note each is on a separate transformer. After anywhere from 5 to 20 minutes the LEDs turn off (each at a different time). There is still 12VAC at the bulb but its not on. If I unplug a bulb from the socket (with power on) and plug it back in that bulb comes on for a couple of minutes and goes off again. It behaves as if the bulbs are overheating but they are only slightly warm (as expected for a 7w bulb) and the package says use 12VAC which is what I have. Its Weird... Anyone know the root cause of this? (FYI I am tired of messing with this and am returning the LEDs to the hardware store and ordering a bunch of Sylvania halogens from Amazon).
I had a hard time with mine. First it was because they were on a dimmer. "dimmable" led bulbs are mostly not or at least weren't for my system. Once I swapped out the dimmer I still had a hard time with standard LED bulbs. I had to buy a whole new set of dimmable bulbs to get them working right. Maybe something with the voltage wasn't stable enough? Sorry for the rant but I'm hoping it gives you some ideas.
