. It took them a while to get to a level of brightness I could live with, but they seemed to flicker with small changes in mains voltage. I sent them back and received these. This is a higher quality version of the same lead brand. They seem to have an economy version that I bought from Costco. They worked great and are very bright. I've changed all the cool white (amber) bulbs in the house so everything now looks like daylight which we like. I know some people don't like daylight, but in my opinion this is the right color, so why not buy daylight bulbs right away? The mix wasn't great so I ended up buying two packs and now everything looks the same at night as it does during the day.
