Bought a set of 4, 2 bulbs used per bulb, 2 bulbs, 4 bulbs total. Office lamps, each connected to a separate socket. The lights are bright enough, which is good. The bulbs work normally for about 2 minutes, then all four flicker terribly for about 10 seconds and then stop flashing. The pattern repeats itself over and over and is very distracting for me from my office. Several people who have visited my office have commented on how distracting and annoying the topics of conversation are.
