⚠️ WARNING ⚠️
These fan units are appearing all over social media and are being sold by various online sellers. I had seen them advertised before, but today I came across one installed in a customer’s property for the first time.
As an electrician, I have concerns about these products.
A standard bayonet or pendant light fitting is designed to support a lamp (bulb) and, where applicable, a lightweight lampshade up to a specified weight. It is not designed to support a motorised fan that creates vibration, movement and twisting forces during operation.
The constant movement can place additional strain on the pendant flex, lampholder and ceiling rose, potentially leading to damage over time. The fitting can wobble, twist and swing while the fan is running, which is not what these fittings were originally designed for.
If you’re considering one of these, please think carefully before purchasing. A proper ceiling fan should be installed on a suitable mounting designed to support the weight and movement of the fan safely.
Just because something screws into a light fitting doesn’t necessarily mean the light fitting was designed to support it.
