UPDATE: They all die after just a year. Almost exactly the day I put them in, they're all dead. All of them started fading a bit on different days and then died after a few days. Several bulbs actually died earlier, for example at 10 months and 11 months. I have used them in 2 different types of bathroom fixtures and clearly have not used them for more than 3 hours a day. So their promise to add 3 hours a day for 13 years is extremely optimistic! I will look for another brand that will last longer. ORIGINAL REVIEW: They don't buzz! They are good and bright. I've only had a few weeks so I don't know how long they will last but if they die I will buy them again.
