Unpainted aluminum tube that connects the 2 gray parts, meanwhile, is so "soft" that he arrived distorted and I hesitate to screw up his no-screw by turning not even a additional round of 16th !!
As for the son junction (black and white, braided, of about 0.25 mm²!?!) They inspire me the greatest distrust to plug in anything other than a top LED lamp few Watts!
By putting a lamp 40W more, I'd be too afraid to burn my shack (I am a teacher of physics, the Joule effect, I know, obviously better than the manufacturer of this product, overpriced for what it is ...)
My advice: look elsewhere ....
