I should comment on the FEIT bulb and quality that.  I tested the emissions with an SA coupled to the line cord and this was done at FULL VOLTAGE.  Meaning the bulbs when powered with 120V AC were quiet.

I did NOT check the dimmed condition on these LED bulbs.

I do have Lutron dimmers throughout the house - but for the bulbs that are tied to these, I have generally stuck with incandescent types on the assumption that 1) a dimmed incandescent bulb lasts a very long time indeed compared with a full-line voltage type and 2) the combination of Lutron + incandescent is radio quiet where I assume that the LED types would be of no benefit and most likly somewhat of a noise source.  There are a few LED FEIT bulbs in the house on generic dimmers but those are only in rooms where they are unoccupied or typically infrequently used when it's radio time.

For the bulbs, I've found all of the FEIT brand bulbs sold by Costco to be quiet also.

FWIW - my experience:  incandesent dimmers don't always work on LED bulbs -
dimmable or otherwise.  I also discovered that not all LED dimmers are
equal.  In this case, I installed LED pot lights and they recommended a
Luxton dimmer.  I bought another brand at a big box and it was toast in
under 2 weeks (total load 140 wts on a 600 wt rating).  Went to electrical supply house to get recommended after consulting with manufactuer support.
Now at 1 year +.  There are some intersting articles about leading v.
trailing edge dimmers for LED lights.  apparently it can matter.
