@engineer,
Hi, thanks for the reply. Its just a simple flush mount fixture that had 3 wires (Black, white and ground). It has three 60-watt bulbs, incandescent, candelabra bulbs (with the small bases). We were stumped when it was blowing the bulbs. I wonder if they were blown because when we flipped the switch on, we only had one of the three bulbs in? After shooting two bulbs, my friend reversed the wires (making black connect with white), then it didn't blow the bulb. But, that time, I physically put the bulb in instead of him and I noticed that it seemed to require more turning to get it to seat properly. I think perhaps he didn't screw them in quite far enough (just pondering that). If that's the case, its probably just a coincidence that when we reversed the wires that it worked. I guess the curious part of me wants to understand WHY it doesn't matter if they are reversed when its an incandescent light??? And...do you think its safe to leave it reversed??? Thanks for any additional feedback...this is VERY helpful!!
