Hlg 350 is dimmed to 50% I need it at 40 but it starts squeezing high pitch from the driver
I heard it’s a frequency switch which causes the leds to vibrate and shortens their life ?

If you run it at 40% and it makes noise I wouldn't do it. Can you set it at 50 or 60% and just raise the light 10 inches until the plants are ready?

That's why I use cheap lights when they have a problem flickering or go out I just chunk them in the trash. It may not be the best thing to do. Maybe using expensive lighting is worth trying.
