I am having a problem with my FC-E6500 grow light. Yesterday when watering I noticed that the light was getting brighter and dimming on its own. I had the light set @ 550watts. I checked with the watt meter and it was reading 459 watts. I turned the dimmer up and the light would only read 715 watts. It usually reads 730-740 watts. I set the light @ 600 watts and left it. Today I went back and checked and it was reading only 450 watts. I turned the power up to max and it would only read 615 watts. Do I have a driver going bad ? I bought this light on Alibaba on November 21, 2021. I have the receipt from PayPal paid to Shenzhen Jiadianguang Technology Co., Ltd. This light should still be under warranty. I hope That if it is the driver, I can get a replacement from Mars Hydro. Any help appreciated.
