I purchased a few of these when I have gone on vacation the last two years from Costco in the US since they either couldn’t be found here or the pricing was way to much to justify.
I really like those A17 bulbs and for $4 you can’t go wrong as they seem to dim quite well. I have them in a few fixtures replacing cfl’s as they burn out. For a 60watt equivalent in the one room where they replaced two 100watt equivalent cfl’s I didn’t notice any drop in output from the well worn cfl’s. I have had three of these in use for almost 2 years now and the seem to be holding up well. I also have a pair of those BR40’s in two floor lamps which are nice. They are definitely a little warmer than what I normally like (usually buy “daylight” cfl’s) but are nice and bright and instant on. These were also bought 2 years ago.
The par30’s are in use at my mom’s place to replace the stock halogen bulb pot lights (5) in her kitchen and she really likes them. We tried a couple different cfl’s in them but the warm up time was dreadful. She also used the first 3pack ones in the bathroom and really likes them compared to the cfl’s before them.
I definitely don’t have a lot of experience with household led lamps since the pricing in Alberta (Canada?) is ridiculous but I haven’t been disappointed with any of these Feit bulbs Costco sells.
