All PUZZ-LED Light pieces are identical.
The pieces are usually assembled with the front facing outwards. Each piece has two curved and two straight edges.
A curved edge is ALWAYS placed over the straight edge of another piece.
First, examine the diagram
The first row is assembled into a rosette. The five pieces of the second row are attached one by one in a ring around the first row's rosette. Turn the work upside-down so that it sits on the table like a bowl. See that all the hooks are correctly joined.
Now the third row is a ring of ten pieces, which are attached to the rim of the "bowl" and also joined to each other. When the sphere is finished, check that all hooks are locked, and that curved edges cover all the straight edges.
The cord with socket and light bulb can now be inserted. The sphere has twelve joints with five hooks in each, and twenty joints with three hooks in each. Loosen two of the hooks in a joint of five, and feed the cord and socket through the joint until the lightbulb hangs in the middle of the sphere.
Close the hooks around the cord.
You can check that the light bulb is in the center by loosening one piece in the side of the sphere and looking in. In the round 30 element lamp, the maximum wattage bulb allowed is 40 W. Smaller lamps require smaller light bulbs.
