Insignia F30 USB port randomly powered while TV off?

I added some cheap LED lights to the back of my F30 (NS75F301NA22). They are powered by the USB port on the TV. They appear to work as expected when the TV is turned on/off. However, when the TV has been off for several hours, I was surprised to see the LED lights come on for a short duration (1 min?), then turn back off. This happens intermittently (don't know if it is happening on a regular interval).

I have turned the LED lights off with the remote when I see this happen, and they turn off as expected. But some time later, with the TV off, I'll see them come on again. Reminds me of behavior on my Mac where it wakes for Network activity. Is there a similar behavior on this Insignia?
