I really wanted these to work but they didn't. I have a ceiling fan light that has two bulbs. One was working and the other wasn't. I put one of these new bulbs in and the working bulb blew out. The new bulb was dim but working. I put a second new bulb in... and neither of them worked. They would flash when I turned the light off or on but they would never stay lit. I thought the light figure had broken but when I went out and bought new bulbs and replaced both of these Bioled bulbs... the light was just fine. The bulbs simply don't work - don't waste your money on them.
