I may have come across lamps from a defective batch, but keep that in mind. Buy at your own risk. It was found that this behavior of the lamp occurs due to being in the lamp turned on at 220. If you turn off the lamp from the outlet for a while and then turn it back on, then the colors and performance return to normal. But in this case, the whole meaning of the "smartness of the lamp" is lost, because. in fact, it is turned off and on manually through the outlet. Alas.
