Do You Have an IKEA Maskros Pendant Lamp - the Big Dandelion/flower Light???

The issue with the lights failing the inspection has to do with how the lights were installed. A licensed electrician would be the most qualified person to provide you with the proper information and installation of these lights.

I doubt this light is a fire hazzard in how it is constructed but needs to be properly installed (wires grounded). Even another light fixture would need to be grounded according to the inspectors.

I hope this helps.

I would ask your contractor to clarify the issue that the inspector found. Is it an issue of installation or an issue with the lamp itself? Or is it an issue with the outlet? I understand you being concerned. If your contractor simply says "don't worry about it" be persistent and ask him to explain. I do know that some inspectors find issues that aren't really issues. For instance, the light could be fine but if you bite down on the cord you could be shocked. Well, duh, but the inspector has to plan for user stupidity and negligence. Ask your contractor or, perhaps, contact an electrician for an second opinion.

Do the lights have the mark of a national testing laboratory, such as (UL)?
If not, return them. Perhaps they were manufactured without the proper grounding conductor. If they do, then it may have been a problem with the method of installation, and they must be installed correctly, to be safe.

I love that light. I don't have it though. I'm no expert, so don't take my word for it, but if you have some kind of low wattage light bulb or LED light I don't think it would catch the paper on fire.

I don't understand what the electrical inspector told you about the grounding, but I would not personally be afraid of having the Maskros lamp.
