I have changed a lot of my bulbs to LED, and have found in my family room, I have can lighting, and after trying many brands, I couldn't get rid of pulsing/flicker. I finally went to a duracell bulb, and with a good dimmer, the flicker is gone! These bulbs also have a 5 yr warranty, and the local store honors it.
