Anet A8 LED lamp

I place this small LED https://www.banggood.com/DC12V-Super-Bright-G4-LED-COB-Corn-Light-Bulb-p-1121572.html?rmmds=myorder&cur_warehouse=CN inside the tube and get an adjustable led lamp. The tube has 6 small balls inside that will hold the LED in place.

The 12V COB LED is close to the specified 1W and get decent light for that usage. There is no polarity on the led, so connection is straight forward. Loop in the back of the clip hold the cable in place.
