I have mounted this lamp without any problems and provided with a LED-saving lamp. Everything was great and also bright enough. I vestehe some reviews here not where it claims will be scrap or inferior. Dear people: EDESTAHL and glass for 23.50 .... what more could you want. If you're looking for a top quality product then you have to stop spending more. What do you expect? And if you have not just two left hands can also tight-fitting steel cover anbringen.Klar reasonable and without injuries this only clamped but it is tight and shaking nicht.Außerdem it must indeed be close, right? All in all a good product, stainless steel, real glass and for little money
