Ikea is recalling two popular glass ceiling lamps due to concerns about their safety.

The Swedish retailer said 11 customers worldwide had been injured after the glass shades, from some of their “Lock” and “Hyby” lamps, had fallen.

In a statement Ikea said: “In a few cases medical treatment was required and one customer reportedly needed stitches.”

Ikea has received 224 reports in total due to the retaining clips breaking.

The company said a full refund would be offered without a receipt.

Ikea has been selling “Lock” lamps since 2012 and the “Hyby” models since 2012.

The lamps have domed white frosted glass shades and three plastic clips that attach the shade to the electrical light fitting.

The retailer said it took product safety very seriously and apologized for the inconvenience.

In January 2016, Ikea asked customers to return LATTJO drum sticks and LATTJO tongue drum as a precautionary measure because of fears they could be a choking hazard for young children.
