I got today very weird lights problems that I cannot understand. I have
6 recessed lights on one circuit in basement: three in one area, three other in another but very close to the first three. When I turned the light switch on today one of recessed light bulb (65 W halogen) blew off. I replaced it with another one and now I have very weird situation. Three lights in the area that I replaced bulb in works only in half power as if they are dimmed by 50%. If I leave only one bulb of three it works OK, if I put the second one, does not matter which they are both dimmed. Three other lights work OK. I checked with multimeter and found that when two bulbs are appeared dimmed the voltage in the third recessed light socket is 120V. Why do I have bulbs dimmed? What could be the reason for this situation? Note, I did replace another bulb but it didn't help. These six lights are switched by regular 3-way switch (not dimmer) and are on 20 A circuit and share the same circuit with 9 recessed lights in another room in basement.- posted
