Bought to replace halogen bulbs that keep burning out. I love the look of halogen bulbs and wanted a warm color similar to standard halogen bulbs. When they arrived I only changed one to see what it would look like. Sure, as an LED, the element inside looked a little different, but it didn't look weird, it actually looked like some of the Edison lightbulbs available. Cut them open that night and couldn't tell which were LED and which were halogen. ***NOTE*** I can't hear anything, but my fiancee can hear the sound of the lightbulbs. As far as I know, this is a high frequency tone. That is the reason for 4 stars instead of 5. I also had a guest who said that they could also hear noises when the lights were on, which proved to me that it wasn't just their opinion. It doesn't matter, and if there are other noises around, she doesn't notice. However, she explained that if we used lightbulbs somewhere, we were around her all the time, she would have problems with it.
