The bulb works very well and I'm satisfied with it. However, in my experience, the indications "15-year life" (written on the front of the packaging) and "3-year guarantee" (written on the back of the packaging) are highly fanciful. In my house, such a bulb has never lasted more than 6 months, a year at best. Indeed, while the filaments don't wear out, the little electronic device hidden in the base of the bulb that makes the connection between the 230 volts and the filaments is absolutely not durable. If this problem could be solved, my rating would be five stars.
So far very satisfied... very nice light color and so far good quality ... am curious...
