A few weeks ago I made this post: LED Driver not producing full power, please help
The company agreed to send me a replacement HLG-320H-48B, and it works, but it has a pretty audible humming noise.
Both lights are at 100% load. Is it normal for a driver to hum? The other one doesn’t hum so I hope I’m not dealing with another faulty driver.
Any insight would be much appreciated.
