I just installed this cheap LED with a brightness of 4600 lumen, which is really great. Now I can finally work without falling asleep.

But.

It's humming, faintly. Which is annoying. Any ideas on how to rectify this?

The LEDs do not hum. Their power supply does. Usually, it is caused by bad coils. I'd check which one is humming, and just replace it, but this might not be a method recommendable for anyone.
