[RFI] Led swing clamp on desk lamps

[leonard keepers]

Hello group just curious. i have not yet purchased one of these lamps 
but i see that they can be powered by usb.? how much of a powered usb 
port or hub is needed for such a lamp to work properly. i am guessing if 
it is plugged into ones computer it would add more work on the computers 
power supply. thank you
