Step 1: Disassembling
Also from the printer I took out that white wire which supports high temperature.
I passed the white wire thought a hollow rigid copper wire, to be used as a stand for the light bulb and also to resist to high temperatures.
The AC cable comes from inside the metal stand, I soldered the wires on the light bulb and isolated them with high temperature tape (kapton)
At the end, I have this super power abajur and it worked very well as a heater, it was the original idea!
