The Consumer Product Safety Commission has issued a recall for 43,700 Classic Quarters floor lamps sold through discount retailer Big Lots of Columbus, Ohio. The wiring for the lamp’s light sockets can become exposed, posing a risk of electric shock to consumers.

The CPSC hasn't received any reports of injuries. However the safety agency notes using a 40 watt light bulb in the defective lamp can also generate excessive heat, which can melt the lamp's double plastic shades. The agency says Big Lots has received four reports from consumers of melting lamp shades.

The recall involves Classic Quarters Five Light Floor Lamps. The lamps stand about five feet tall, have a gunmetal or chrome colored metal pole and five adjustable lights mounted on flexible metal tubes at the top. Dark plastic or multi-colored double plastic shades cover each of the five lights.

Recalled lamps use standard incandescent or CFL bulbs and have labels marked with the model number “G-1843-5” affixed to the underside of the lamp base. These lamps can be further identified by SKU numbers 612007239, 612007829 or 612008982 at the beginning of the instructions. Lamps that use candelabra bulbs are not subject to this recall and can be identified by labels marked with the model number “G-1844-5B” and SKU numbers 612009036 or 612009037 in the instructions.

The defective lamps were sold exclusively at Big Lots stores nationwide from April 2010 through November 2011 for between $30 and $50.

Consumers should immediately stop using the lamps and return them to a Big Lots store for a full refund.
