I've had them since May last year. My first lightbulb blew out yesterday, I didn't spend a fortune on it so I went with an open mind. I love bright white and such. I expected the bulbs to last a little over 17 months but we'll see how long the others last and check them out. If I were to calculate the price per bulb versus how many days it ran before it went out, I'm sure it would still be worth comparing it for efficiency. My faulty bulb has the bottom ring blackened while the rest is white, doesn't feel/smell/look burnt so I'm confused.
