LED Lamp Buzzing (not a bulb) Answered

About a year ago, I came across this LED lamp that was on sale at my local Target store. It caught my eye because it had a little tray at the base of the lamp along with a USB port for charging my devices. Since the first time I plugged it in and turned it on, it makes a buzzing noise. At first it didn't bother me, but now that I am spending more time at my workbench it has become annoying. I understand it is kind of common for LED bulbs to do this because of the dimmer switch being outdated, however this lamp is not dimmable nor is it a "bulb" so to say. It's about 7-9 SMD LEDs on a circuit with a rocker switch. If it makes a difference, I do have my lamp plugged into a surge protector and don't have anything plugged into the USB port located at the base of the lamp.

What can be done (other than throwing it away, of course) to stop the buzzing noise coming from the lamp?

Thanks in advance!

The reason for LEDs to make buzzing noise is that old DIMMER switches are incompatible with LEDs, which causes vibrations in the light bulb, which then is heard as HUM or buzzing coming from the light bulbs

The buzzing is from the transformer used to reduce the voltage for the LED and USB port.
Not much you can do except check if it is loose or to replace te whole thing.
