Review on Ceiling Dimmable Chandelier Chandeliers Lighting Lighting & Ceiling Fans by Mary Crawford

Installed by an electrician and was initially a little confused by the colors of the wires and harness as they weren't standardized like things that were manufactured in the USA. He installed it in about 15 minutes. When I turn on the light switch, sometimes the light comes out at 100% brightness cool white, other times when I turn on the light it comes out at around 80% brightness and warm white. Very strange, not sure if the ECU could be faulty or what. Would you appreciate feedback if someone else saw the same problem and was able to solve it?
