Swedish furniture retailer Ikea is recalling two types of ceiling lamps because of a risk that the glass shades might fall and injure people.

The company says that after receiving complaints from customers that the shades of some "Lock" and "Hyby" lamps had fallen and caused injuries, it's urging all buyers of the two ceiling lamps to immediately return them to an Ikea store for a full refund.

Ikea on Tuesday apologized for the inconvenience and said customers don't need to produce a receipt to prove purchase of the items for a refund.

Ikea has been selling "Lock" lamps in all its markets since 2002 and the "Hyby" models since 2012.
