Trying to get some advice, as I'm a bit stumped. I have 2 separate circuits in the basement, both with recessed lighting. These are 15a circuits. For sake of ease-- Circuit A has 8 bulbs, while Circuit B has 4 bulbs. Circuit A is also attached a few other outlets in the house, Circuit B is not.
Both circuits are using the Lutron AYCL-153P Dimmer, and are on 3 way switches with a regular (On/Off) switch as well. The bulbs I am using are Cree BBR30-06527FLF-12DE26-1U100's. One by one, I've noticed that the bulbs are starting to flicker to the point where they might be completely turned off for milliseconds at a time. Once the bulb has been affected, it stays with the bulb no matter which socket to place it in. This behavior has been observed on both A and B circuits. I don't often dim the lights; and the flicker occurs anywhere from full brightness all the way to the lowest dimmer setting.
I've exchanged a few of the bulbs already, it seems to be a temporary fix for a few months, but then another bulb starts to act up a week or two later. I'm not sure where to go from here. Could the 3 way switches be affecting the bulbs? Am I just really unlucky with bulb picking (3 of 12 bulbs already exchanged)? Could the fixtures be playing a fiendish role in any of this? Any advice would be appreciated, I'm not sure what to do at this point.
Random side note-- they all buzz (figure there's no getting around that) but not enough to drive me crazy; which is surprising, because I find I'm pretty sensitive to noises like that.
