This puzzle light is good and can be sold cheap, because it is primarily composed of 30 interlocking plastic identical parts. Plus points are: + She looks good. + It is very convenient. + The assembly is fun, similar to a puzzle game. Minus points are: - The material absorbs more light than similar lights that are not puzzling, so it is darker at the same bulbs. - The exchange of the light source in case of defect becomes quite complicated because the top puzzle pieces have to be disassembled. Therefore, it is highly recommended to use a long-life LED lamps. I run these lights with 24W energy-saving lamps and regret the day when one of them needs to be changed. - The lamp requires very small hook on the ceiling to hang, so that the cover can be pushed up to the ceiling. This is due to the execution of the strain relief used in the supply line. Since we have more hooks on the ceiling, I have therefore replaced the strain relief by those of the old lamps.
