I find these shelves great, apart from the fact that they are cheaper at IKEA (also online incl. Shipping) ... The suspension structure is made of a flat plate on the two pipes are welded. About these pipes and the flat sheet the shelf is then plugged and "floats" so on the wall. Since there is only inside of a "cardboard honeycomb structure", it is very light and has yet a high load capacity. Have two LED recessed spotlights used in one of these shelves, complete with transformer which was very easy and so due to the construction of the shelf. If you include the radiator upward, one has nice indirect light ...
