3-Light Polished Chrome Integrated LED Pendant with Clear Cube Glass

Long read but WORTH the read. Failure Mode: When power applied via either of two 3-ways switches two LEDs would not light at all and the third flashes on and off like a strobe light. Note that there are NO dimmer switches used in my application. 1. I removed the 3 pendent LED light from ceiling and powered it up on bench, the 3 pendent LED light worked fine. 2. I then replaced the original LED driver with the new LED driver thinking possible flaky connection inside the original LED driver module. After replacing the LED driver the 3 pendent LED light worked fine. (Note on bench powering: I powered the 3 pendent LED light with a plug that has about one foot of wire. The phase/power and neutral wires are stripped bare at end. I then used wire nuts to connect phase/power and neutral to 3 pendent LED light and then plugged in to wall outlet. 3. Since the 3 pendent LED light worked fine on bench I then reinstalled the 3 pendent LED light on ceiling box and same failure mode. The failure mode is two of three LEDs do not light and third strobes just as seen in attached video. 4. The 3 pendent LED light is powered through two 3-way switches. I replaced both switches and this did not correct the situation. 5. I then took the 3 pendent LED light down and powered on bench a third time and once again worked on bench. I could not duplicate the failure mode on the bench. 6. I then measured voltage at ceiling receptacle box, 122V. I connected a 120V bulb socket to phase/power and neutral wires in ceiling box and both a normal medium (E26) base 60 watt incandescent and13 watt LED bulb worked fine. 7. The next step was to divide and conqueror. I pulled the first switch in-line with regard to power feed from breaker box to 3 pendent LED light out of its box. I am nearly 100% sure the power, neutral and ground wire feeding this box is a direct run from breaker box. I connected the 3 pendent LED light to this first switch in-line. I removed the wire nut from the neutrals and connected the neutral from the 3 pendent LED light directly to the 3 neutral wires that were twisted tightly together using a jumper wire. I connected power on the 3 pendent LED light to the switch using a jumper wire and 3 pendent LED light worked fine. 8. I then repeated this for the second switch in-line and 3 pendent LED light worked fine. I then ran a temporary power cord from the ceiling box where the 3 pendent LED light is normally connected and powered the 3 pendent LED light on while lying on the floor and 3 pendent LED light worked fine. 9. With some trepidation I then decided to wire the 3 pendent LED light directly to the ceiling box and it is WORKING. Note that I did solder coat the power and neutral wires that feed the LED driver to allow for a better wire nut connection. Conclusion: It had to be a neutral connection issue but which one I am not sure. There must have been a very slightly loose or slightly corroded neutral somewhere with emphasis on slightly. The neutrals in the boxes where the switches located looked neatly and tightly twisted when I removed wire nuts. There is only one power and neutral connection in the ceiling box. The reason I conclude it had to be a neutral issue is that is this is the only connections I played with on the second day. The first day the neutrals were not disturbed except for neutral in ceiling box. That neutral was disturbed/used each time the 3 pendent LED light wired to ceiling box. Because that neutral was disturbed/used three different times it would be hard to believe ceiling neutral connection was the problem?? It is also difficult to believe that the neutral connections in boxes were the problem because they were twisted neatly and tightly. The LED driver design must be extremely sensitive to neutral connection. We already know that I measured 122 volts at the ceiling box and both a Medium (E26) Base incandescent and LED light both worked when wired to ceiling box. Hard for me to believe the 3 pendent LED light was malfunctioning due a poor neutral connection leading to current limitation issue. The incandescent light was 60 watt and would draw more power than the 3 pendent LED light. My best guess is some type of noise injection that the LED driver could not handle. Lousy design IMO. Recall I am not the only individual experiencing this strobe malfunction. I saw many similar complaints online. Weirdest electrical issue I ever encountered that I can recall. IMO this product should be subjected to recall with improved LED driver design lights replacing the recall product.

No, this item is LED integrated and there are no bulbs to be used.

There is an LED driver in the base that is dimmable in mine. The information about LED driver can be read off driver.

Yes. We adjusted all of ours to accommodate the space.
