Magnet useThe porcelain sea urchins only stay on the thin steel discs because they are held in place by tiny 3 x 3 mm neodymium magnets. For one lamp I implement a total of 27 disc magnets.
The completed lampHere you can see the finished lamp turned on at night.
Attention - humidity!
Please note that neodymium magnets are not suitable for use in humid areas and need to be insulated.
