So far we have received three boxes of four lamps. The first box of 4 didn't fade much. The second box of four faded as expected. I sent back the first box of 4. We received the third box of four and the lights in that box went out like the lights in the first box of four. We will return the third box for a replacement. The figure shows the difference between a slight and insufficient dimming of the lamps in the first and third drawer and an adequate dimming of the four lamps in the second drawer. If and until we receive a set of lamps that work as advertised (dimmable) we will not be able to give a higher rating. If all the bulbs worked the same as the bulbs in the second drawer, the bulbs would get a 5 star rating.
